Last week I gave a talk in the parallel sessions about my work in the characterization of the TDCs, both the semi-analog and the fully-digital. In this link there is my presentation in Indico, and below is my presentation, which can also be viewed in “full screen” in this link.
Last week I completed the characterization of the “fully digital” TDC, Stephan Wiederkehr’s design. In this link there is the report, which I embed here: Just in case, the report is in this GitHub repo and the current version is in this commit. This TDC design “competes” against the “semi analog” design of Beat, which …
Introduction I am working in the development of a position+time readout chip for 4D pixel detectors in collaboration with the group at PSI. The project has already started when I joined and there are already some designs that have been implemented in test structures, which have to be characterized. For this, the group at PSI …
After a lot of assembling, programming, measuring, analyzing and calibrating, today I finally arrived to my very first results of spacial and temporal resolution in an AC-LGAD. Though it was a lot of work until I reached here, the methods still have to be improved. The results I obtained, however, are pretty good. In this …
After my first timing measurement with the TCT, presented in this post, I started to play a little bit with timing in an AC-LGAD installed in the TCT. Playing around with different settings in the oscilloscope I noted that the temporal resolution seems to improve if, instead of using the rising edge, the falling edge …
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. …
We have in our lab a scanning TCT by Particulars which produces laser pulses. We want to do timing measurements with this so we need a time reference and a pulse. The best condition for this would be to have two separate laser pulses shifted in time by a fixed delay. One way to ensure …
