[Gate-users] Surfaces definition in GATE v9.0

[Carlotta Trigila]

Dear GATE Users,

I am specifically addressing this e-mail to anyone using optical simulations and surface definition with GATE v9.0.

I noticed that in the last versions of GATE the definition of the surfaces for optical simulations has to be performed AFTER the "/gate/run/initialize" command.
E.g. from optical.mac benchmark example
"

/gate/run/initialize


# Definition of surfaces

/gate/detector/surfaces/name                             Detection1

/gate/detector/surfaces/insert                           Electronics

/gate/detector/surfaces/Detection1/setSurface            perfect_apd

/gate/Electronics/surfaces/name                          Detection2

/gate/Electronics/surfaces/insert                        detector

/gate/Electronics/surfaces/Detection2/setSurface         perfect_apd

"

If we move these commands BEFORE the initialization, the simulation crashes with a message like
"[G4-cerr] ***** Illegal application state </gate/detector/surfaces/insert Electronics> *****".
However, I am sure that with GATE v8.0 (and older) we were able to define them BEFORE the initialization. I am not sure of what happens with the v8.2.

Did someone ever notice it before? Did you have an idea of what could have changed?

Many thanks for your help,

Carlotta Trigila

Subject: Re: [Gate-users] GATEv9.0 Scintillation Process is NOT working.(Solved)

Thx for your report,

The aim of my fix is to make scintillation working for the combination
 "GATEv9.0  (with my patch) + Geant4.10.06.p02 "

Can you test it, if you have time  ?
