AUTHORS MESSAGE Linear
--------------- Linear
THE REPORT DESCRIBED ABOVE IS THE LATEST PUBLISHED DOCUMENTATION Linear
FOR THIS PROGRAM. HOWEVER, THE COMMENTS BELOW SHOULD BE CONSIDERED Linear
THE LATEST DOCUMENTATION INCLUDING ALL RECENT IMPROVEMENTS. PLEASE Linear
READ ALL OF THESE COMMENTS BEFORE IMPLEMENTATION. Linear
Linear
AT THE PRESENT TIME WE ARE ATTEMPTING TO DEVELOP A SET OF COMPUTER Linear
INDEPENDENT PROGRAMS THAT CAN EASILY BE IMPLEMENTED ON ANY ONE Linear
OF A WIDE VARIETY OF COMPUTERS. IN ORDER TO ASSIST IN THIS PROJECT Linear
IT WOULD BE APPECIATED IF YOU WOULD NOTIFY THE AUTHOR OF ANY Linear
COMPILER DIAGNOSTICS, OPERATING PROBLEMS OR SUGGESTIONS ON HOW TO Linear
IMPROVE THIS PROGRAM. HOPEFULLY, IN THIS WAY FUTURE VERSIONS OF Linear
THIS PROGRAM WILL BE COMPLETELY COMPATIBLE FOR USE ON YOUR Linear
COMPUTER. Linear
Linear
PURPOSE Linear
------- Linear
THIS PROGRAM IS DESIGNED TO CONVERT ENDF/B FILE 3, 23 AND 27 DATA Linear
TO LINEAR-LINEAR INTERPOLABLE FORM. ANY SECTION THAT IS ALREADY Linear
LINEAR-LINEAR INTERPOLABLE WILL BE THINNED. Linear
Linear
IN THE FOLLOWING DISCUSSION FOR SIMPLICITY THE ENDF/B TERMINOLOGY Linear
---ENDF/B TAPE---WILL BE USED. IN FACT THE ACTUAL MEDIUM MAY BE Linear
TAPE, CARDS, DISK OR ANY OTHER MEDIUM. Linear
Linear
ENDF/B FORMAT Linear
------------- Linear
THIS PROGRAM ONLY USES THE ENDF/B BCD OR CARD IMAGE FORMAT (AS Linear
OPPOSED TO THE BINARY FORMAT) AND CAN HANDLE DATA IN ANY VERSION Linear
OF THE ENDF/B FORMAT (I.E., ENDF/B-I, II,III, IV, V OR VI FORMAT). Linear
Linear
IT IS ASSUMED THAT THE DATA IS CORRECTLY CODED IN THE ENDF/B Linear
FORMAT AND NO ERROR CHECKING IS PERFORMED. IN PARTICULAR IT IS Linear
ASSUMED THAT THE MAT, MF AND MT ON EACH LINE IS CORRECT. SEQUENCE Linear
NUMBERS (COLUMNS 76-80) ARE IGNORED ON INPUT, BUT WILL BE Linear
CORRECTLY OUTPUT ON ALL LINES. THE FORMAT OF SECTION MF=1, MT=451 Linear
AND ALL SECTIONS OF MF=3 MUST BE CORRECT. THE PROGRAM COPIES ALL Linear
OTHER SECTION OF DATA AS HOLLERITH AND AS SUCH IS INSENSITIVE TO Linear
THE CORRECTNESS OR INCORRECTNESS OF ALL OTHER SECTIONS. Linear
Linear
OUTPUT FORMAT Linear
------------- Linear
IN THIS VERSION OF LINEAR ALL ENERGIES WILL BE OUTPUT IN Linear
F (INSTEAD OF E) FORMAT IN ORDER TO ALLOW ENERGIES TO BE WRITTEN Linear
WITH UP TO 9 DIGITS OF ACCURACY. IN PREVIOUS VERSIONS THIS WAS AN Linear
OUTPUT OPTION. HOWEVER USE OF THIS OPTION TO COMPARE THE RESULTS Linear
OF ENERGIES WRITTEN IN THE NORMAL ENDF/B CONVENTION OF 6 DIGITS Linear
TO THE 9 DIGIT OUTPUT FROM THIS PROGRAM DEMONSTRATED THAT FAILURE Linear
TO USE THE 9 DIGIT OUTPUT CAN LEAD TO LARGE ERRORS IN THE DATA Linear
DUE TO TRUNCATION OF ENERGIES TO 6 DIGITS DURING OUTPUT. Linear
Linear
CONTENTS OF OUTPUT Linear
------------------ Linear
ENTIRE EVALUATIONS ARE OUTPUT, NOT JUST THE LINEARIZED DATA Linear
CROSS SECTIONS, E.G. ANGULAR AND ENERGY DISTRIBUTIONS ARE ALSO Linear
INCLUDED. Linear
Linear
DOCUMENTATION Linear
------------- Linear
THE FACT THAT THIS PROGRAM HAS OPERATED ON THE DATA IS DOCUMENTED Linear
BY THE ADDITION OF 3 COMMENT LINES AT THE END OF EACH HOLLERITH Linear
SECTION IN THE FORM Linear
Linear
***************** PROGRAM LINEAR (2018-1) **************** Linear
FOR ALL DATA GREATER THAN 1.00000-10 IN ABSOLUTE VALUE Linear
DATA LINEARIZED TO WITHIN AN ACCURACY OF 0.1 PER-CENT Linear
Linear
THE ORDER OF SIMILAR COMMENTS (FROM RECENT, SIGMA1 AND GROUPIE) Linear
REPRESENTS A COMPLETE HISTORY OF ALL OPERATIONS PERFORMED ON Linear
THE DATA BY THESE PROGRAMS. Linear
Linear
THESE COMMENT LINES ARE ONLY ADDED TO EXISTING HOLLERITH SECTIONS, Linear
I.E., THIS PROGRAM WILL NOT CREATE A HOLLERITH SECTION. THE FORMAT Linear
OF THE HOLLERITH SECTION IN ENDF/B-V DIFFERS FROM THE THAT OF Linear
EARLIER VERSIONS OF ENDF/B. BY READING AN EXISTING MF=1, MT=451 Linear
IT IS POSSIBLE FOR THIS PROGRAM TO DETERMINE WHICH VERSION OF Linear
THE ENDF/B FORMAT THE DATA IS IN. WITHOUT HAVING A SECTION OF Linear
MF=1, MT=451 PRESENT IT IS IMPOSSIBLE FOR THIS PROGRAM TO Linear
DETERMINE WHICH VERSION OF THE ENDF/B FORMAT THE DATA IS IN, AND Linear
AS SUCH IT IS IMPOSSIBLE FOR THE PROGRAM TO DETERMINE WHAT FORMAT Linear
SHOULD BE USED TO CREATE A HOLLERITH SECTION. Linear
Linear
REACTION INDEX Linear
-------------- Linear
THIS PROGRAM DOES NOT USE THE REACTION INDEX WHICH IS GIVEN IN Linear
SECTION MF=1, MT=451 OF EACH EVALUATION. Linear
Linear
THIS PROGRAM DOES NOT UPDATE THE REACTION INDEX IN MF=1, MT=451. Linear
THIS CONVENTION HAS BEEN ADOPTED BECAUSE MOST USERS DO NOT Linear
REQUIRE A CORRECT REACTION INDEX FOR THEIR APPLICATIONS AND IT WAS Linear
NOT CONSIDERED WORTHWHILE TO INCLUDE THE OVERHEAD OF CONSTRUCTING Linear
A CORRECT REACTION INDEX IN THIS PROGRAM. HOWEVER, IF YOU REQUIRE Linear
A REACTION INDEX FOR YOUR APPLICATIONS, AFTER RUNNING THIS PROGRAM Linear
YOU MAY USE PROGRAM DICTIN TO CREATE A CORRECT REACTION INDEX. Linear
Linear
SECTION SIZE Linear
------------ Linear
SINCE THIS PROGRAM USES A LOGICAL PAGING SYSTEM THERE IS NO LIMIT Linear
TO THE NUMBER OF POINTS IN ANY SECTION, E.G., THE TOTAL CROSS Linear
SECTION MAY BE REPRESENTED BY 200,000 DATA POINTS. Linear
Linear
FOR ANY LINEARIZED SECTION THAT CONTAINS 60000 OR FEWER POINTS Linear
THE ENTIRE OPERATION WILL BE PERFORMED IN CORE AND THE LINEARIZED Linear
DATA WILL BE OUTPUT DIRECTLY TO THE ENDF/B FORMAT. FOR ANY SECTION Linear
THAT CONTAINS MORE POINTS THE DATA WILL BE LINEARIZED A PAGE AT A Linear
TIME (1 PAGE = 60000 POINTS) AND OUTPUT TO SCRATCH. AFTER THE Linear
ENTIRE SECTION HAS BEEN LINEARIZED THE DATA WILL BE READ BACK FROM Linear
SCRATCH AND OUTPUT TO THE ENDF/B FORMAT. Linear
Linear
SELECTION OF DATA Linear
----------------- Linear
THE PROGRAM SELECTS DATA TO BE LINEARIZED BASED EITHER ON EITHER Linear
MAT (ENDF/B MAT NO.) OR ZA AS WELL AS MF AND MT NUMBERS. THIS Linear
PROGRAM ALLOWS UP TO 100 MAT/MF/MT OR ZA/MF/MT RANGES TO BE Linear
SPECIFIED BY INPUT PARAMETERS. THE PROGRAM WILL ASSUME THAT THE Linear
ENDF/B TAPE IS IN MAT ORDER, REGARDLESS OF THE CRITERIA USED Linear
TO RETRIEVE MATERIALS. IF RETRIEVAL IS BY MAT RANGE THE PROGRAM Linear
WILL TERMINATE WHEN A MAT IS FOUND THAT IS ABOVE ALL REQUESTED Linear
MAT RANGES. IF RETRIEVAL IS BY ZA RANGE THE PROGRAM WILL SEARCH Linear
THE ENTIRE ENDF/B TAPE. Linear
Linear
PROGRAM OPERATION Linear
----------------- Linear
EACH SECTION OF DATA IS CONSIDERED SEPARATELY. EACH SECTION OF Linear
ENDF/B DATA TO LINEARIZE IS REPRESENTED BY A TABLE OF ENERGY Linear
VS. CROSS SECTION AND ANY ONE OF FIVE ALLOWABLE INTERPOLATION LAWS Linear
BETWEEN ANY TWO TABULATED POINTS. THIS PROGRAM WILL REPLACE EACH Linear
SECTION OF DATA CROSS SECTIONS BY A NEW TABLE OF ENERGY VS. Linear
CROSS SECTION IN WHICH THE INTERPOLATION LAW IS ALWAYS LINEAR IN Linear
ENERGY AND CROSS SECTION BETWEEN ANY TWO TABULATED POINTS. Linear
Linear
DATA IS READ AND LINEARIZED A PAGE AT A TIME (ONE PAGE CONTAINS Linear
60000 DATA POINTS). IF THE FINAL LINEARIZED SECTION CONTAINS TWO Linear
PAGES OR LESS, DATA POINTS IT WILL BE ENTIRELY CORE RESIDENT Linear
AFTER IT HAS BEEN LINEARIZED AND WILL BE WRITTEN DIRECTLY FROM Linear
CORE TO THE OUTPUT TAPE. IF THE LINEARIZED SECTION IS LARGER THAN Linear
TWO PAGES, AFTER EACH PAGE IS LINEARIZED IT WILL BE WRITTEN TO Linear
SCRATCH. AFTER THE ENTIRE SECTION HAS BEEN LINEARIZED IT WILL Linear
BE READ BACK FROM SCRATCH, TWO PAGES AT A TIME, AND WRITTEN TO Linear
THE OUTPUT TAPE. Linear
Linear
KEEP EVALUATED DATA POINTS Linear
-------------------------- Linear
SOMETIMES IT IS CONVENIENT TO KEEP ALL ENERGY POINTS WHICH WERE Linear
PRESENT IN THE ORIGINAL EVALUATION AND TO MERELY SUPPLEMENT THESE Linear
POINTS WITH ADDITIONAL ENERGY POINTS IN ORDER TO LINEARIZE THE Linear
CROSS SECTIONS. FOR EXAMPLE, IT IS OFTEN CONVENIENT TO KEEP THE Linear
THERMAL VALUE (AT 0.0253 EV) OR THE VALUE AT 14.1 MEV. Linear
Linear
THE CURRENT VERSION OF THIS PROGRAM WILL ALLOW THE USER TO KEEP Linear
ALL ORIGINAL EVALUATED DATA POINTS BY SPECIFYING 1 IN COLUMNS Linear
34-44 OF THE FIRST INPUT LINE. THIS WILL TURN OFF THE BACKWARD Linear
THINNING (SEE UCRL-50400, VOL. 17, PART A FOR EXPLANATION) AND Linear
RESULT IN ALL ORIGINAL ENERGY POINTS BEING KEPT. CAUTION SHOULD Linear
BE EXERCISED IN USING THIS OPTION SINCE IT CAN RESULT IN A Linear
CONSIDERABLE INCREASE IN THE NUMBER OF DATA POINTS OUTPUT BY Linear
THIS CODE. Linear
Linear
FOR ALL USERS WHO ARE NOT INTERESTED IN THIS OPTIONS NO CHANGES Linear
ARE REQUIRED IN THE INPUT TO THIS PROGRAM, I. E. IF COLUMNS Linear
34-44 ARE BLANK (AS FOR ALL PREVIOUS VERSIONS OF THIS CODE) THE Linear
PROGRAM WILL OPERATE EXACTLY AS IT DID BEFORE. Linear
Linear
ALLOWABLE ERROR Linear
--------------- Linear
ALLOWABLE ERROR MUST ALWAYS BE SPECIFIED IN THE INPUT TO THIS Linear
PROGRAM AS A FRACTION, NOT A PER-CENT. FOR EXAMPLE, INPUT THE Linear
ALLOWABLE FRACTIONAL ERROR 0.001 IN ORDER TO OBTAIN DATA THAT IS Linear
ACCURATE TO WITHIN 0.1 PER-CENT. Linear
Linear
THE CONVERSION OF THE DATA FROM THE GENERAL INTERPOLATION FORM TO Linear
LINARLY INTERPOLABLE FORM CANNOT BE PERFORMED EXACTLY. HOWEVER, IT Linear
CAN BE PERFORMED TO VIRTUALLY ANY REQUIRED ACCURACY AND MOST Linear
IMPORTANTLY CAN BE PERFORMED TO A TOLERANCE THAT IS SMALL COMPARED Linear
TO THE UNCERTAINTY IN THE CROSS SECTIONS THEMSELVES. AS SUCH THE Linear
CONVERSION OF CROSS SECTIONS TO LINEARLY INTERPOLABLE FORM CAN BE Linear
PERFORMED WITH ESSENTIALLY NO LOSE OF INFORMATION. Linear
Linear
THE ALLOWABLE ERROR MAY BE ENERGY INDEPENDENT (CONSTANT) OR ENERGY Linear
DEPENDENT. THE ALLOWABLE ERROR IS DESCRIBED BY A TABULATED Linear
FUNCTION OF UP TO 20 (ENERGY,ERROR) PAIRS AND LINEAR INTERPOLATION Linear
BETWEEN TABULATED POINTS. IF ONLY ONE TABULATED POINT IS GIVEN THE Linear
ERROR WILL BE CONSIDERED CONSTANT OVER THE ENTIRE ENERGY RANGE. Linear
WITH THIS ENERGY DEPENDENT ERROR ONE MAY OPTIMIZE THE OUTPUT FOR Linear
ANY GIVEN APPLICATION BY USING A SMALL ERROR IN THE ENERGY RANGE Linear
OF INTEREST AND A LESS STRINGENT ERROR IN OTHER ENERGY RANGES. Linear
Linear
DEFAULT ALLOWABLE ERROR Linear
----------------------- Linear
IN ORDER TO INSURE CONVERGENCE OF THE LINEARIZING ALGORITHM THE Linear
ALLOWABLE ERROR MUST BE POSITIVE. IF THE USER INPUTS AN ERROR Linear
THAT IS NOT POSITIVE IT WILL AUTOMATICALLY BE SET TO THE DEFAULT Linear
VALUE (CURRENTLY 0.001, CORRESPONDING TO 0.1 PER-CENT) AND Linear
INDICATED AS SUCH IN THE OUTPUT LISTING. Linear
Linear
COULOMB PENETRABILITY (INTERPOLATION LAW = 6) Linear
-------------------------------------------- Linear
INTRODUCED FOR ENDF/B-VI. THIS IS DEFINED AS, Linear
Linear
SIG(E) = C1*EXP(-C2/SQRT(E - T)) Linear
Linear
THIS PROGRAM ONLY CONSIDERS EXOTHERMIC REACTIONS - T = 0 Linear
Linear
SIG(E) = C1*EXP(-C2/SQRT(E)) Linear
Linear
WARNING...THIS INTERPOLATION LAW SHOULD ONLY BE USED FOR REACTIONS Linear
WHICH HAVE A POSITIVE Q-VALUE (EXOTHERMIC REACTIONS), Linear
SINCE HERE WE ONLY CONSIDER T = 0.0 IN THE FORMALISM. Linear
IN ALL OTHER CASES A WARNING MESSAGE WILL BE PRINTED. Linear

INPUT PARAMETERS Linear
---------------- Linear
FOR VERSIONS EARLIER THAN 90-1 THIS PROGRAM ONLY ALLOWED THE USER Linear
TO SPECIFY BY INPUT PARAMETERS WHICH MATERIALS (MAT) TO PROCESS. Linear
FOR EACH REQUESTED MATERIAL NEUTRON INTERACTION CROSS SECTIONS Linear
(MF=3) WOULD BE LINEARIZED AND THE REMAINDER OF THE MATERIAL Linear
WOULD BE COPIED. Linear
Linear
FOR VERSIONS 90-1 AND LATER THIS PROGRAM WILL ALLOW THE USER TO Linear
TO SPECIFY BY INPUT PARAMETERS EXACTLY WHAT SECTIONS OF DATA Linear
TO PROCESS. FOR EACH SECTION OF DATA, SPECIFIED BY MAT, MF, MT Linear
RANGES, SECTIONS OF MF=3, 23 AND 27 WILL BE LINEARIZED AND ALL Linear
OTHER REQUESTED SECTIONS WILL BE COPIED. ALL SECTIONS WHICH ARE Linear
NOT EXPLICITLY REQUESTED WILL BE SKIPPED AND WILL NOT APPEAR ON Linear
ENDF/B FILE OUTPUT BY THIS PROGRAM. Linear
Linear
WITH THIS NEW PROCEDURE YOU CAN MINIMIZE THE SIZE OF THE ENDF/B Linear
FILE OUTPUT BY THIS PROGRAM, E.G., IF YOU ONLY WANT NEUTRON Linear
CROSS SECTIONS FOR SUBSEQUENT PROCESSING YOU NEED ONLY REQUEST Linear
ONLY MF=3 DATA. Linear
Linear
HOWEVER, YOU MUST UNDERSTAND THAT ONLY THOSE SECTIONS WHICH YOU Linear
EXPLICITLY REQUEST WILL APPEAR ON THE ENDF/B FILE OUTPUT BY Linear
THIS PROGRAM. FOR EXAMPLE, IF YOU WISH TO DOCUMENT EXACTLY Linear
HOW YOU LINEARIZED THE DATA BY INCLUDING COMMENTS IN MF=1, MT=451 Linear
THEN YOU MUST EXPLICITLY REQUEST THAT MF=1, MT=451 BE PROCESSED Linear
FOR EACH MATERIAL THAT YOU REQUEST. SIMILAR IF YOU WANT THE Linear
ENTIRE EVALUATION YOU MUST REQUEST ALL MF AND MT TO BE OUTPUT. Linear

ENERGY LIMITS OF THE PAGE (THIS OPTION MAY BE Linear
USED IN ORDER TO MONITOR THE EXECUTION SPEED Linear
OF LONG RUNNING JOBS). Linear
23-33 MINIMUM CROSS SECTION OF INTEREST (BARNS). Linear
(IF 0.0 OR LESS IS INPUT THE PROGRAM WILL Linear
USE 1.0E-10). ENERGY INTERVALS WILL NOT BE Linear
SUB-DIVIDED IF THE ABSOLUTE VALUE OF THE CROSS Linear
SECTION WITHIN THE INTERVAL IS LESS THAN THIS VALUE. Linear
AN EXCEPTION TO THIS RULE IS NEAR THRESHOLDS ENERGY Linear
INTERVALS WILL BE SUB-DIVIDED UNTIL CONVERGENCE Linear
REGARDLESS OF THE MAGNITUDE OF THE CROSS SECTION. Linear
34-44 KEEP ORIGINAL EVALUATED DATA POINTS. Linear

UP TO 100 RANGES MAY BE SPECIFIED, ONLY ONE RANGE Linear
PER LINE. THE LIST OF RANGES IS TERMINATED BY A Linear
BLANK LINE. IF THE UPPER MAT LIMIT OF ANY REQUEST Linear
IS LESS THAN THE LOW LIMIT IT WILL BE SET EQUAL TO Linear
THE LOWER LIMIT. IF THE UPPER LIMIT IS STILL ZERO Linear
IT WILL BE SET EQUAL TO 999999. IF THE UPPER MF OR Linear
MT LIMIT IS ZERO IT WILL BE SET TO 99 OR 999 Linear
RESPECTIVELY. Linear
VARY 1-11 ENERGY FOR ERROR LAW Linear
12-22 ALLOWABLE FRACTIONAL ERROR FOR ERROR LAW. Linear
THE ACCEPTABLE LINEARIZING ERROR MAY BE SPECIFIED TO Linear
BE EITHER ENERGY INDEPENDENT (DEFINED BY A SINGLE Linear
ERROR), OR ENERGY DEPENDENT (DEFINED BY UP TO 20 Linear
ENERGY, ERROR PAIRS). FOR THE ENERGY DEPENDENT CASE Linear
LINEAR INTERPOLATION WILL BE USED TO DEFINE THE ERROR Linear
AT ENERGIES BETWEEN THOSE AT WHICH IT IS TABULATED. Linear
IN ALL CASES THE ERROR LAW IS TERMINATED BY A BLANK Linear
LINE. IF ONLY ONE ENERGY, ERROR PAIR IS GIVEN THE Linear
THE LAW WILL BE CONSIDERED TO BE ENERGY INDEPENDENT. Linear
IF MORE THAN ONE PAIR IS GIVEN IT WILL BE CONSIDERED Linear
TO BE ENERGY DEPENDENT (NOTE, ENERGY INDEPENDENT Linear
FORM WILL RUN FASTER THAN THE EQUIVALENT ENERGY Linear
DEPENDENT FORM). FOR AN ENERGY DEPENDENT ERROR LAW Linear
ALL ENERGIES MUST BE ASCENDING ENERGY ORDER. FOR Linear
CONVERGENCE OF THE LINEARIZING ALGORITHM ALL ERRORS Linear
MUST BE POSITIVE. IF AN ALLOWABLE ERROR IS NOT Linear
POSITIVE IT WILL BE SET EQUAL TO THE STANDARD OPTION Linear
(CURRENTLY 0.001, CORRESPONDING TO 0.1 PER-CENT). Linear
IF THE FIRST ERROR LINE IS BLANK IT WILL TERMINATE Linear
THE ERROR LAW AND THE ERROR WILL BE TREATED AS Linear
ENERGY INDEPENDENT, EQUAL TO THE STANDARD OPTION Linear
(CURRENTLY 0.1 PER-CENT). (SEE EXAMPLE INPUT 4). Linear
