digitization problem in AllPix_v1.1alpha
Opened this issue · 1 comments
Dear all,
I am testing the version after the geometry changes, with the timepix digitization for some reason I get no or only a small number of digitized hits with small charge.
The energy depositions seem correct to me. The sensor volume use to be centred around Z=0 now its shifted so may be this is a problem for the digitization. Can some one check this?
Cheers, Erik.
I did some more debugging and it seems the problem is related to the calculation of the relative position of the energy deposition w.r.t. the pixel.
If I replace the following line in AllPixTrackerSD.cc:
// correctedPos = correctedPos - centerOfPixel - m_relativePosOfSD;
correctedPos = correctedPos - centerOfPixel;
I get sensible digitization results again.
it would be useful if someone could cross check this piece of code to see it really does what is should do.
Kind regards, Erik.
