Hi HoSeung,
Results are normalized per primary (in your case per incident electron).
Thus, to normalize your results per minute you need to multiply those by 7.5E12 x 250 * 60:
Results 7.5E12 e 250 pulse 60 s
----------- x --------------- x --------------- x -----------
e pulse s min
Please note that Gy is the unit for absorbed dose density [J/kg], so you should score it in your target of interest, not in air (unless you want to know the absorbed dose in air).

Subject: [fluka-discuss]: Dose calculation (Unit: Gy/min)
Dear Fluka users,
I am conducting a simulation with 15 MeV electron beam to tunsgen target to generate photon and neutron. After the target, I put conical shape collimator to focus the photon. I want to calculate a photon dose (Gy/min) at the certain distance from the target (example: 1m, 2m, 3m and etc.).
1. For a input card, I used USRBIN (dose-eq), AUXSCORE (photon) to score the photon equivalent dose, and the unit is pSv/primary. Is this true?
The specification of the accelerator is as follows;
- number of electrons per pulse: 7.5*10^12
- pulse frequency: 250Hz
- pulse duration: 6us
With these parameters, I want to calculate a photon-dose (Gy/min) with FLUKA. I am a beginner of this program and this field. Can you tell me how to calculate Gy/min at certain point (or surface) with a little bit detail?
Thank you in advance.
Regards,
Ho-seung SONG
