Hi Micheal,

I think it is due to the Detector_LUT, since it "detects" the optical photons: no photos are transmitted.
Can you please try using another LUT on the photodetector face, e.g., PolishedBare (although not optimal), and check if your results change?

If yes, don't hesitate to contact me, I have several crystal-grease LUTs I can share with you. Moreover, you can generate your own LUT using an app developed this year (https://aapm.onlinelibrary.wiley.com/doi/epdf/10.1002/mp.14863?saml_referrer)

Subject: [Gate-users] Optical Simulation Pixel

Im working with optical simulations using LUT davis model, but i'm facing some problems in order to get the pixelID response from the simulation.

i.e :

I'm simulating a monolithic crystal associated with an array detector, but, i can't read any information in pixelID. It shows it's value ranging from -1-0, and containing all single events, as if it was a single element, but actually it was repeated in the code.

I've also noticed that if I use depth 2  ( to sum the pulse in the pixel using optical system) the singles tree shows no data. The tree appears and also all its leaves but no information is shown. I can only obtain data if using readout depth 0 or 1.

The surfaces crystal-apd apd-crystal were set as "Detector_LUT" and the crystal's surfaces were set to PolishedESR_LUT.

is there any configuration that i'm missing? how to solve this problem?
