Hi All,

 

Gavin and I discovered last week that the production (pentagonal) sTGC geometry only produces GEANT hits in only about 40% of events. I did not catch this before, because I was not checking the absolute efficiency (events / total with tracks) but only the efficiency with respect to the number of MC tracks (reco / MonteCarlo). The hits have the correct distribution – it is not that part of the detector is missing, just that hits are lost on most events.

 

Jason, this is a fairly urgent issue for us – as we cannot proceed with alignment or any of the other current tasks with this outstanding.

Could we have a zoom meeting about this in the next few days. I am available in the afternoon today (Monday) or Tuesday.

 

Best,

Daniel
