Multi-Purpose Detector (MPD) system is a part of new accelerator complex (Nuclotron-based Ion Collider fAcility - NICA) located in Dubna, Russia. MPD to meet all functionalities and requirements needs designed another trigger system. That trigger system has two main task: first, responsibility for off-beam calibration of MPD subdetectors and second, identification and rejection of cosmic ray particles. Additionally, the system can be also used to observe cosmic showers initiated by high energy primary particles. To define in details requirements of the MPD Cosmic Ray Detector (MCORD), the consortium NICA-PL has been formed. In the consortium participate many polish scientific institutions. This paper presents an electronic readout system for the MCORD project. It briefly describes the data path of the signals and all signal processing subsystems: scintillators equipped with SiPM (Silicon Photo Multipliers) detector, AnalogFront End (AFE), HUB, and MTCA processing system.

The single mirror Small Size Telescope (SST-1M) project proposes a design among others for the smallest type of telescopes (SST), that will compose the south observatory of the Cherenkov Telescope Array (CTA). The SST camera collecting the Cherenkov light resulting from very high energy gamma-ray interactions in the atmosphere proposes to use Silicon PhotoMultipliers (SiPM). The SST-1M design has led to the use of unique pixel shape and size that required a dedicated development by the University of Geneva and Hamamatsu. An active surface of ~94 mm2 and a resulting total capacitance of ~3.4 nF combined with the stringent requirements of the CTA project on timing and charge resolution have led the University of Geneva to develop a custom preamplifier stage and slow-control system. The design and performance of the tailor made preamplifier stage and of the slow control electronics will be briefly described. The bias circuit of the sensor contains a resistor meant to prevent the sensor from drawing high current. However this resistor also introduces a voltage drop at the sensor input impacting the stability of its operation. A model has been developed in order to derive the parameters needed to account for it at the data analysis level. A solution based on the SST-1M front-end and digital readout is proposed to compensate for the voltage drop at the sensor cathode.
