PURPOSE
Mixer

-------
Mixer

THIS PROGRAM IS
DESIGNED TO CALCULATE THE ENERGY DEPENDENT CROSS   Mixer

SECTION FOR A
COMPOSITE MIXTURE OF UP TO 10 DIFFERENT MATERIALS.   Mixer

Mixer

THE PRESENT
VERSION WILL ONLY CALCULATE THE CROSS SECTION FOR ONE  Mixer

FINAL REACTION
(ENDF/B SECTION), E.G. TOTAL CROSS SECTION, BUT NOT Mixer

ANY OTHER
REACTION.
Mixer

Mixer

NOTE, THIS
PROGRAM WILL NOT COMBINE ALL REACTIONS FOR A MIXTURE    Mixer

OF MATERIALS
DURING A SINGLE RUN - ONLY ONE REACTION WILL BE       Mixer

CREATED PER
RUN.
Mixer

Mixer

EVALUATED DATA
FORMAT
Mixer

---------------------
Mixer

THE CROSS SECTIONS ARE
READ FROM THE ENDF/B FORMAT AND THE
Mixer

COMPOSITE CROSS
SECTION IS CONVERTED TO AN EQUIVALENT BARNS/ATOM   Mixer

FORM AND OUTPUT
IN THE ENDF/B FORMAT WITH AN EQUIVALENT ATOMIC     Mixer

WEIGHT. THE USER
MUST SPECIFY THE COMPOSITION BY GIVING THE ZA,    Mixer

MT AND GRAMS/CC
OF EACH CONSTITUENT. IN ADDITION THE USER MUST     Mixer

IDENTIFY THE
COMPOSITE CROSS SECTION BY SPECIFYING THE ZA, MAT     Mixer

AND MT TO BE USED
IN THE ENDF/B FORMATTED OUTPUT.
Mixer

Mixer

SINCE ONLY THE
CROSS SECTIONS IN FILE 3 AND 23 ARE USED, AND THE   Mixer

FORMAT FOR FILE
3/23 IS THE SAME IN ALL VERSIONS ON ENDF/B, THIS   Mixer

PROGRAM MAY BE
USED WITH ANY VERSION OF ENDF/B DATA (I.E.,
Mixer

ENDF/B-I, II,
III, IV, V OR VI). DURING A SINGLE RUN IT MAY EVEN   Mixer

BE USED TO READ
AND COMBINE EVALUATIONS WHICH ARE IN DIFFERENT     Mixer

VERSIONS OF THE
ENDF/B FORMAT.
Mixer

Mixer

ENDF/B FORMATTED
OUTPUT WILL BE IN THE ENDF/B-VI FORMAT REGARDLESS Mixer

OF THE FORMAT OF
THE INPUT ENDF/B DATA. THIS WILL ONLY EFFECT THE  Mixer

HOLLERITH
SECTION (MF=1, MT=451). THE FORMAT OF CROSS SECTIONS     Mixer

(MF=3) IS THE
SAME IN ALL VERSION OF THE ENDF/B FORMAT.            Mixer

Mixer

IN ORDER TO
GUARANTEE PROPER OPERATION OF THIS PROGRAM THE DATA    Mixer

MUST BE PROPERLY
CODED IN THE ENDF/B FORMAT. NO ERROR CHECKING IS  Mixer

PERFORMED. IT IS
PARTICULARLY IMPORTANT THAT THE FOLLOWING DATA    Mixer

BE CORRECT
Mixer

Mixer

(1) ZA, MF, MT -
MUST BE CORRECT IN ORDER TO ALLOW PROGRAM TO      Mixer

SELECT THE APPROPRIATE SECTIONS TO BE COMBINED.
Mixer

(2) AWRE -
ATOMIC WEIGHT RATIO MUST BE CORRECT TO ALLOW PROGRAM    Mixer

TO CONVERT THE USER SPECIFIED GRAMS/CC INTO ATOMS/CC FOR       Mixer

PROPER ATOM RATIO MIXING.
Mixer

(3) (ENERGIES,
CROSS SECTIONS) - MUST BE CORRECT, LINEARLY
Mixer

Mixer

THIS PROGRAM
WILL ALLOW YOU TO PROCESS EITHER NEUTRON OR PHOTON    Mixer

CROSS SECTIONS -
BUT YOU CANNOT MIX THE TWO TYPES TOGETHER. BY     Mixer

INPUT YOU CAN

DEFINING THE
COMPOSITION
Mixer

------------------------
Mixer

THE USER MAY
SPECIFY UP TO 10 DIFFERENT SECTIONS OF DATA TO BE     Mixer

COMBINED, EACH
SECTION IDENTIFIED BY ZA AND MT NUMBER. THE
Mixer

AMOUNT OF EACH
MATERIAL IS SPECIFIED BY DEFINING THE NUMBER OF     Mixer

GRAMS/CC OF EACH
MATERIAL IN THE COMPOSITE MIXTURE. THIS CAN BE    Mixer

DERIVED FROM THE
VOLUME FRACTION SIMPLY BY MULTIPLYING THE STP     Mixer

DENSITY OF EACH
MATERIAL BY ITS VOLUME FRACTION. NOTE, DO NOT      Mixer

INPUT ATOM
FRACTIONS.
Mixer

Mixer

THE LIST OF
SECTIONS TO BE COMBINED MAY BE SPECIFIED IN ANY
Mixer

ORDER, I.E. THEY
NEED NOT BE IN ZA ORDER OR THE ORDER THAT THE     Mixer

EVALUATED DATA
APPEARS ON THE ENDF/B FORMATTED TAPE.
Mixer

Mixer

IF ANY REQUESTED
SECTION OF DATA IS NOT FOUND ON THE ORIGINAL      Mixer

ENDF/B FORMATTED
FILE, THE PROGRAM WILL PRINT A LIST OF THE
Mixer

MISSING SECTIONS
AND TERMINATE. IF ALL REQUESTED SECTIONS ARE      Mixer

FOUND THE PROGRAM
WILL PRODUCE A COMPOSITE SECTION USING THE       Mixer

UNION OF ALL ENERGIES FOUND IN ANY SECTION. THE COMPOSITE

PAGING SYSTEM
Mixer

-------------
Mixer

THERE IS NO
LIMIT TO THE THE NUMBER OF DATA POINTS IN EACH OF THE  Mixer

SECTIONS TO BE
COMBINED, NOR IS THERE A LIMIT TO THE NUMBER OF     Mixer

DATA POINTS IN
THE COMPOSITE MIXTURE CROSS SECTION.
Mixer

Mixer

ALL REQUIRED
SECTIONS OF DATA ARE READ FROM THE ORIGINAL ENDF/B    Mixer

FORMATTED FILE.
ANY SECTION OF 60000 OR FEWER POINTS WILL BE       Mixer

TOTALLY CORE
RESIDENT. LARGER SECTIONS ARE LOADED INTO A PAGING    Mixer

SYSTEM USING A
SCRATCH FILE WITH ONLY 60000 POINTS PER SECTION     Mixer

CORE RESIDENT AT
ANY ONE TIME. SIMILARLY THE COMPOSITE SECTION     Mixer

WILL BE TOTALLY
CORE RESIDENT IF IT CONTAINS 60000 OR FEWER POINTS Mixer

AND LARGER
COMPOSITE SECTIONS WILL BE LOADED INTO A PAGING
Mixer

SYSTEM WHERE
ONLY 60000 POINTS ARE CORE RESIDENT AT ANY TIME. SINC Mixer

A PAGING SYSTEM
MAY BE USED BY ANY SECTION OF DATA THERE IS NO     Mixer

LIMIT TO THE
SIZE OF EITHER THE ORIGINAL SECTIONS, NOR TO THE      Mixer

COMPOSITE
SECTION, E.G. A SECTION MAY CONTAIN 100,000 ENERGIES     Mixer

AND CROSS
SECTIONS TO DESCRIBE A GIVEN REACTION.

PAGE SIZE
Mixer

---------
Mixer

THE PAGE SIZE
USED IN THIS PROGRAM IS DEFINED BY THE PARAMETER     Mixer

NPAGE AND THE
DIMENSIONS OF THE ARRAYS XTAB AND YTAB. IN ORDER     Mixer

TO ADAPT THIS
PROGRAM FOR USE ON ANY COMPUTER THE PAGE SIZE MAY    Mixer

BE INCREASED OR
DECREASED BUT THE FOLLOWING RULES MUST BE FOLLOWED Mixer

====
Mixer

Mixer

(1) NPAGE - MUST
BE A MULTIPLE OF 3 IN ORDER TO ALLOW THE PROGRAM  Mixer

TO READ FULL CARDS OF ENDF/B DATA (3 POINTS PER LINE). FAILURE
Mixer

TO FOLLOW THIS RULE CAN LEAD TO LOSS OF DATA AND/OR PROGRAM    Mixer

ERRORS DURING EXECUTION.
Mixer

(3) YTAB  - THE DIMENSION OF YTAB MUST BE
(NPAGE,11).
Mixer

(4) XTAB  - THE DIMENSION OF XTAB MUST BE
(NPAGE,11).

DOPPLER
BROADENING
Mixer

------------------
Mixer

THE COMPOSITE
CROSS SECTION OUTPUT FROM THIS PROGRAM SHOULD NOT    Mixer

BE DOPPLER
BROADENED USING PROGRAM SIGMA1, OR THE EQUIVALENT. THE  Mixer

ATOMIC WEIGHT
USED TO IDENTIFY THE COMPOSITE MIXTURE IS BASED ON   Mixer

THE ATOM
FRACTION OF EACH CONSTITUENT AND CANNOT BE USED TO
Mixer

CHARACTERIZE THE
BROADENING OF ANY GIVEN RESONANCE IN THE MIXTURE  Mixer

DUE TO THE
CONTRIBUTION OF ONE CONSTITUENT. IN ORDER TO CONSIDER   Mixer

DOPPLER
BROADENING FIRST USE PROGRAM SIGMA1 TO BROADEN THE CROSS   Mixer

SECTION FOR EACH
OF THE CONSTITUENTS AND THEN COMBINE THE
Mixer

BROADENED DATA
USING PROGRAM MIXER.
Mixer

Mixer

EXAMPLE USE
Mixer

-----------
Mixer

THE OUTPUT FROM
THIS PROGRAM HAS BEEN FOUND TO BE EXTREMELY
Mixer

USEFUL IN THE
FOLLOWING APPLICATIONS...
Mixer

Mixer

(1) CALCULATE A
COMPOSITE TOTAL CROSS SECTON FOR LATER USE AS      Mixer

A WEIGHTING FUNCTION IN SELF-SHIELDING THE CROSS SECTIONS      Mixer

OF EACH CONSTITUENT OF THE
MIXTURE SEPARATELY.
Mixer

Mixer

PROGRAM GROUPIE CAN USE THE CALCULATED COMPOSITE TOTAL CROSS   Mixer

SECTION AS THE TOTAL CROSS SECTION FOR EACH CONSTITUENT OF     Mixer

THE MIXTURE IN ORDER TO CALCULATE
SELF-SHIELDED CROSS SECTION Mixer

FOR EACH CONSTITUENT OF THE MIXTURE.
Mixer

Mixer

(2) CALCULATE
COMPOSITE TOTAL AND FISSION CROSS SECTIONS IN
Mixer

ORDER TO CALCULATE THE TRANSMISSION AND SELF-INDICATION
Mixer

THROUGH COMPOSITE MATERIALS. GENERALLY IN THIS CASE THE
Mixer

TOTAL CROSS SECTION WILL BE CALCULATED FOR THE COMPOSITION     Mixer

OF THE SAMPLE AND THE FISSION CROSS SECTION WILL BE
Mixer

CALCULATED FOR THE COMPOSITION OF THE FISSION CHAMBER
Mixer

(WHICH GENERALLY WILL HAVE A DIFFERENT COMPOSITION THAN THE    Mixer

SAMPLE).
Mixer

Mixer

PROGRAM VIRGIN CAN USE THE OUTPUT FROM THIS PROGRAM TO
Mixer

PERFORM TRANSMISSION AND SELF-INDICATION CALCULATIONS.
Mixer

PROGRAM VIRGIN WILL ANALYTICALLY CALCULATE THE UNCOLLIDED      Mixer

(I.E. VIRGIN) FLUX TRANSMITTED AND REACTION RATE DUE TO ANY    Mixer

TABULATED LINEARLY INTERPOLABLE INCIDENT SPECTRUM. RESULTS     Mixer

WILL BE PRESENTLY FOR UP TO 10 DIFFERENT SAMPLE THICKNESSES    Mixer

AND BINNED INTO ENERGY GROUPS IN ORDER TO SIMULATE AN
Mixer

EXPERIMENTAL MEASUREMENT.
Mixer

Mixer

(3) THE OUTPUT
FROM THIS PROGRAM IS VERY USEFUL TO PLOT IN ORDER   Mixer

TO SEE THE IMPORTANCE OF SPECIFIC CROSS SECTION FEATURES IN    Mixer

THE COMPOSITE CROSS SECTION.
Mixer

Mixer

PROGRAM COMPLOT CAN BE USED TO PLOT THE OUTPUT FROM THIS       Mixer

PROGRAM AND IF REQUIRED EXAMINE ANY PARTICULAR ENERGY RANGE    Mixer

IN DETAIL. IN ORDER TO DO THIS THE (ZA, MT) EQUIVALENCE OPTION
Mixer

OF PROGRAM COMPLOT SHOULD BE USED. TO COMPARE ANY CONSTITUENT  Mixer

CROSS SECTION TO THE COMPOSITE CROSS SECTION THE INPUT TO      Mixer

COMPLOT SHOULD EQUATE THE (ZA,MT) OF THE COMPOSITE TO THE      Mixer

(ZA,MT) OF ONE CONSTITUENT AND THE MULTIPLIER INPUT TO
Mixer

COMPLOT SHOULD BE THE ATOM FRACTION FOR THE CONSTITUENT (THE   Mixer

ATOM FRACTIONS ARE DEFINED IN THE OUTPUT LISTING FROM PROGRAM  Mixer

MIXER).
