[Gate-users] Pileup module

[Martín Belzunce]

Dear Gaters,
I'm having problems when using the pilup module in the digitizer. I am
simulating an hexagonal NaI scanner, and I am trying to simulate the
pile up in each of the six crystals. But when I processed the
simulation, I got much more pile up than expected. In order to
simulate a similar effect, I used a nonparalysable deadtime module and
I got a coincidence rate three times bigger than when using pileup
module. I was expecting to have a similar coincidence rate in both
simulations.
Anybody had this kind of problem with pileup module?
Best regards,
Martín Belzunce





These are the two modules I inserted in the digitizer:

PILE UP MODULE
/gate/digitizer/Singles300n/insert pileup
/gate/digitizer/Singles300n/pileup/setDepth 2
/gate/digitizer/Singles300n/pileup/setPileup 300 ns
/gate/digitizer/Singles300n/pileup/verbose 2

EQUIVALENT DEADTIME MODULE
/gate/digitizer/Singles300n/insert deadtime
/gate/digitizer/Singles300n/deadtime/setDeadTime 300 ns
/gate/digitizer/Singles300n/deadtime/setMode nonparalysable
/gate/digitizer/Singles300n/deadtime/chooseDTVolume cabezal
