Last Upgrades of Roman Pot Electronics

This article presents the recent (2017-2018) electronics modifications for the upgrade o the TOTEM roman pot detectors at the CERN LHC. To improve the timing accuracy and reliability the new Roman Pot detector configuration utilizes both DSDD (Double Side Diamond Detector) an silicon (UFSD, Ultra Fast Silicon Detector) mounted on hybrid boards. The electronics described was designed, built and tested by the authors in Faculty of Electrical Engineering in Pilse Department of Applied Electronics and Telecommunications, University of West Bohemia and by the TOTEM experiment at CERN. With the new detector setup, timing measurements with resolution down to tens of picoseconds are possible.
