[Gate-users] Noise parameters

[Ashley Devarim]

Dear Gate users,
 
I need help please, how can I set up the parameters of noise using the following commands to reproduce a real case, especially noise time distribution parameters  :
 
/gate/distributions/name energy_distrib
/gate/distributions/insert Gaussian
/gate/distributions/energy_distrib/setMean 450 keV
/gate/distributions/energy_distrib/setSigma 1 keV
/gate/distributions/name dt_distrib
/gate/distributions/insert Exponential
/gate/distributions/dt_distrib/setLambda 7.57 mus
/gate/digitizer/Singles/insert noise
/gate/digitizer/Singles/noise/setDeltaTDistribution dt_distrib
/gate/digitizer/Singles/noise/setEnergyDistribution energy_distrib
 
 
Also, I don't understand : The special event ID, event_ID= -2 , is attributed for those noise events. why GATE consider noise events as a separated events !!!  is that what happens in real life ?
 
 
Looking forward to your answer
and Thank you very much for your help
 
Ashley
