In PERC the main detector for the measurement of electrons from the free neutron beta decay will initially be a scintillation detector. In a later upgrade it will be exchanged with a 2mm thick silicon PIN detector. I present the results of the first characterization.

In order to characterize detectors for PERC with electron energies up to 1MeV, were located the ELISE spectrometer, which was designed and built at the University of Heidelberg. The system was completely overhauled, and in particular the slow-control and interlock system were upgraded. The system is now fully operational again and I present its current capabilities.
