[Gate-users] energy spectrum

[Dounia Taleb]

Dear Gaters,


I am using gateV4 and I want to model an old cylindrical gamma camera 
to study the energy spectrum of detected photons. First, I thought that 
an opticaladder plus defining materials.xml would be enough to succeed. 
Nevertheless I read in the user guide that when trcking optical photons 
one can never get information about energy.
I tried to use the "normal" adder then but the emission peak of the 
lead(in shielding and parallel hole collimator) usually around 90 keV  
is missing when compared to experimental spectrum...
Does anyone encounter this problem before?

Any kind of help would be very appreciated.

Cheers,
Dounia
