Euclid STAR Prize 2019 Instrument Award for CPPM and IPNL team

le 05 Jun, 2019

The characterization team’s expertise is based on an early experience with IR detectors in the framework of the SNAP collaboration and expanded to the highest level within the Euclid project. The team members combine strong complementary skills: mechanical and thermal design of the bench, software development for acquisition and bench control & automation, instrumentation, test procedures of pixel detectors. Thanks to the close collaboration of CPPM & IPNL, the team has developed and validated dedicated test facilities of high quality and excellent running efficiency with a fully automated...

eBOSS/DESI France meeting

le 09 Oct, 2018

The CPPM and the LAM were very pleased to host the eBOSS-DESI France meeting for its 4th edition on October 4 and 5, 2018. One of the goals of these series of informal eBOSS-DESI meetings is to put in contact researchers working in similar topics within eBOSS and DESI collaborations. On this occasion, a visit of the Winlight company in Pertuis was organised, Winlight being responsible for the construction of DESI's ten spectrographs, which are to be delivered to Mayall between 2018 and 2019.

LSST automated filter exchanger - Transport and low temperature tests

le 08 Mar, 2018

CPPM has built a prototype of the automated filter exchanger for the LSST telescope, "The Auto Changer". After a few months of development and tests, it has just been transported to Paris for tests at low temperature (-10 ° C) and for combined tests with other complementary instruments. The Auto Changer traveled well by truck and was quickly put back into service by Aurélien Marini and Fabrice Gallo. We were able to succeed in cold chamber tests: at -10 ° C for power-up, and at -5 ° C for nominal operation. These operations made it possible to verify that the mechanics designed by...
