On the Canary island of La Palma (Spain), Cédric Champion, from APC Electronics, backed up remotely by Michael Punch (physicist at APC), are participating in the integration campaign of the prototype Large-Sized Telescope (LST) with the Cherenkov Telescope Array Observatory (CTAO) Array Control and Data Acquisition System (ACADA).
 
The LST has been in commissioning as a single Imaging Cherenkov...

Artist's impression of the Vela pulsar, in the centre, and its magnetosphere, whose edge is marked by the bright circle. The blue tracks travelling outwards represent the paths of accelerated particles. These produce gamma radiation along the arms of a rotating spiral by colliding with infrared photons emitted in the magnetosphere (in red). © Science Communication Lab for DESY

Vue d’artiste du pulsar de Vela, au centre, et sa magnétosphère, dont la périphérie est marquée par le cercle brillant. Les traces bleues émergeant vers l’extérieur illustrent les trajectoires des particules accélérées. Celles-ci produisent le rayonnement gamma le long des bras d’une spirale tournante, par collisions avec des photons infrarouges émis dans la magnétosphère (en rouge). © Science Communication Lab for DESY

Flicker noise impact and design methodology in SiGe BiCMOS integrated front-end electronics for astronomical observations

Increasing the number of sensitive pixels in an instrument is a classical way to improve its observational capabilities. From cosmology, in the millimeter wave range, to high-energy astrophysics space instruments, the readout of thousands of cryogenic detectors requires dedicated electronic developments. Application-specific integrated circuits - ASICs offer major advantages in this context : specific design, small size and optimized performances.
