Description
In the context of the Pentadimensional Tracking Space Detector project (PTSD), we are currently developing a demonstrator to increase the Technological Readiness Level of LGAD Si-microstrip tracking detectors for applications in space-borne instruments. Low Gain Avalanche Diodes (LGAD) is a consolidated technology developed for particle detectors at colliders which allows for simultaneous and accurate time (<100 ps) and position (~ 10 µm) resolutions with segmented Si sensors. It is a candidate technology that could enable for the first time 5D tracking (position, charge, and time) in space using LGAD Si-microstrip tracking systems. The intrinsic gain of LGAD sensors may also allow to decrease the sensor thickness while achieving signal yields similar to those of Si-microstrips currently operated in Space.
In this contribution we discuss the activities for the design and development of a low-consumption LGAD Si-microstrip device. We also discuss possible applications and breakthrough opportunities in next generation large area cosmic-ray and sub-GeV gamma-ray detectors that could be enabled by LGAD Si-microstrip tracking detectors in Space, and we propose the design of a cost-effective instrument to be deployed on a CubeSat platform to enable and qualify the operations of LGAD Si-microstrip detectors in Space.
