Description
The ITS3 upgrade will introduce a new bent wafer-scale MAPS detector, which makes use of air-cooling instead of water-cooling. This reduces the material budget significantly, but cooling might become less homogeneous. In this project, the functionality and performance of the APTS, DPTS and BabyMOSS chips were investigated across various temperature ranges, offering the opportunity for investigating the sensor performance at different stages of signal processing.
For this, a test setup was constructed to create a stable, temperature-controlled environment, enabling systematic investigations.
Temperature dependent parameters that were examined are the operating range and the waveform of the analogue signal after pulsing of the APTS. For the BabyMOSS, the threshold, number of noisy pixels and the fake hit rate were studied. Additionally, the DPTS was pulsed in order to perform a waveform analysis of the digital output, as well as the encoding timing parameter were investigated.
