Dear Adrian,
1. There is a typo in your example "JI", must be "IJ".
2. You can use JTRACK to check FLUKA particle number, for electron JTRACK=3.
3. Primary particle has LLO = 1, so second generation electrons will
have LLO = 2.
C Energy deposition from second generation electrons.
IF (ISCRNG .EQ. 1) THEN
IF ((JTRACK .NE. 3) .AND. (LLO .NE. 2)) LSCZER = .TRUE.
END IF
Best regards,
Mikhail
