Asteroid's temperature control commissioned

November 25, 2020

The temperature control of the ASTEROID cryostat has been commissioned during Sept-Oct, 2020.

After the simulation and tuning of the PID controllers, the dummy detector reached a relative temperature error of 0.5 mK at 100K and 50K, both exceeding the current temperature stability requirements.

The next stage will be the integration with the custom SWIR optical setup to readout the ALFA detector, an ESA’s HgCdTe detector prototype developed by the consortium as a probe of concept.

The commissioning results and the temperature performance are presented in the coming online conference SPIE Astronomical Telescopes + Instrumentation 2020.
