Dear Fluka experts,
I want to simulate the transport process of electrons being injected into a Ta target and record the data of photoneutrons. With MGDRAW user routine, I can get the age of the neutron by variable ATRACK. But when I modified the MGDRAW.f file as follow: SUBROUTINE MGDRAW ( ICODE, MREG )
IF ( JTRACK .EQ. 8 ) THEN
WRITE (92,*) NTRACK, MTRACK, JTRACK, SNGL (ETRACK),
& SNGL (WTRACK)
WRITE (92,*) ( SNGL (XTRACK (I)), SNGL (YTRACK (I)),
& SNGL (ZTRACK (I)), I = 0, NTRACK ),
& ( SNGL (DTRACK (I)), I = 1, MTRACK ),
& SNGL (CTRACK)
WRITE (92,*) SNGL (CXTRCK), SNGL (CYTRCK), SNGL (CZTRCK),
& SNGL (ATRACK), LTRACK
ENDIF
I will get the data as follow(here I only show the data of one neutron for example):
1 0 8 0.939982057 9.70298983E-03
0.322248042 6.06961399E-02 5.58620729E-02 -5.55111512E-17 9.48838666E-02 -0.100359999 0.359747052
-0.895762861 9.50326771E-02 -0.434255302 4.14305951E-10 4
1 0 8 0.939982057 9.70298983E-03
-5.55111512E-17 9.48838666E-02 -0.100359999 -79.0000000 8.47609901 -38.3986320 88.1929855
-0.895762861 9.50326771E-02 -0.434255302 9.92574911E-08 4
These data means that there are two step of this neutron, so 3 point of the path exist. However, there are only two data of the age of the neutron. Why? If I want to get the birth time of neutron, which age is what I need? Is it the first one? If it is ture, what is the age of neutron at the end point of the last step?
Best Regards
Qi
