Recently I came across the problem of having to precisely measure the charge produced by a PIN detector from the RD50 FBK TI-LGAD production. As we know, PINs have no internal gain and since this one is from the TI-LGAD production it is only 45 micrometers thick. Thus, the signals are really small and the …

I designed a new “flavor” of the Santa Cruz board that is basically the same circuit but with a smaller layout, such that I can place more of them simultaneously in the climate chamber, and also thinking in an easier mounting in the TCT with cooling. In the first tests I made yesterday, the board …
In a previous post I presented a brief bibliographical research on what is supposed to happen in a silicon detector when 1) a MIP particle passes through it and 2) when an infrared laser pulse is shined onto it. Today I want to bring this to real life and see what I get. I am …
The other day I decided to start working on the MIP calibration of the TCT and so I installed one of the PIN diodes we have. To do the MIP calibration basically we have to compare the collected charge when the device is excited by a MIP particle, e.g. a beta electron, and the collected …
