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 ongoing activities for the design, development, and test of a breadboard laboratory model for verification of requirements, functionalities and space qualification of LGAD Si-microstrip devices for 5D tracking in space. We also present the study performed at the Italian Space Agency - Concurrent Engineering Facility (ASI-CEF) addressing the design of a LGAD-tracker flight-demonstrator to be housed in a 6U-XL CubeSat platform. The possible, successful operations in space of the demonstrator could confirm the TRL of Si-microstrip LGAD-trackers to 9, making it a viable and available technology for future mission opportunities for charged cosmic-ray and γ-ray instruments.
