Abstract

For the MWIR channel of the spectrometer of the ESA Ariel mission, ESA has procured a dedicated MCT detector from TeledyneE2V with a cut-off of 8µm at 42K.A test bench has been designed, manufactured and commissioned to measure the performances of the detector at cryogenic temperature. The detector was tested before, during and after proton radiation performed at 42K up to a level of 2.50E+10 p+/cm².The results of the impact of the proton radiation on the detector performances are presented as well as a description of the test bench.
