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 …

So far, for all sensor studies, I have been using either a single channel active board (Santa Cruz or Chubut) or a multi channel passive readout board. Though this works, it is not ideal. Firstly, the passive readout board is not the best because usually the amplifier is installed as close as possible to the …
In this post I will present the Robocold beta setup a.k.a. the LGAD long term test setup, LGAD stability test setup, etc. The first presentation of this setup I made it about one year ago in this link. After that, other projects appeared, also the climate chamber was failing, so I ended up delaying the …
In the later months we have engaged in the market survey for the sensors of the CMS MTD. A long time has passed since my previous post focused on the beta setup and I have learned a lot. However, I was still not able to reach the final expected time resolution for the detectors. After …
Recently we received our new MCP-PMT of which I presented a first test in this post. Today I am posting the first serious characterization of the device. All the details can be found in this document which I embed below: As a summary, I measured a time resolution of about 22-24 ps for the MCP-PMT …

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 …
Today I was able to finally perform the very first timing measurement with our TCT at UZH. In this post I will describe the setup and the results. Setup description Below there is a block diagram of the setup: The pulsed infrared laser[1]1064 nm, part of our Particulars TCT. is coupled to an optic fiber. …
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 …
