Our family of quad modules (2x2 CROC prototypes for the Phase-II upgrade of the CMS pixel detector) has a new member:

This is the first HPK one - produced by Hamamatsu, with wafer layout done here in Hamburg - that we have wirebonded and fully assembled. Right now it undergoes first tests in the laboratory. Next week it will be characterised at the DESY testbeam.

First testbeam of the year

Last week we had our first testbeam of the year. This time, we took data in area T24 of the DESY II test beam facility to test Low Gain Avalanch Diodes (LGADs) at different voltages and under different beam incidence angles.
