In 2003, within the ULTRA experiment framework, the SDI widely contributed to the manufacturing, the implementation and the on-site installation of the ET-Scope set, intended to detect the particles from atmospheric sparks in association with the INFN of Turin and the IASF teams of Palermo, Italy.
These detectors among five, constituted of wide plates of scintillateurs associated to photomultipliers, were deployed on the measurement site, near the Mount Cenis dam in Savoie (photo of the site below), twice during two measuring campaigns of two weeks, in October, 2002 and June, 2003.
During these campaigns, the department assured the implementation of the on-site device as well as the logistics and the provision of an acquisition system. The data measurements in which we widely participated, were made during moonless nights, necessary conditions for good measurements.
Furthermore, a new type of detector (Belenos), developed by the SDI, intended to measure the Ultraviolet signals (250-450nm) associated to the atmospheric sparks also installed. The preliminary tests made in July, 2003 on the first prototype demonstrated the efficiency of this device.
At the end of the year on 2003 the ET-Scope was installed on site of the LPSC to make tests and long term measurements.
The installation of the CODALEMA experiment, on the site of the radio telescope of Nançay, continued until 2007. The department deployed four new stations of scintillators detection in March, 2006, so coming to complete 5 stations already installed in 2005. The capture of data with this network of new detectors continued till the end of 2006.
In January, 2007, in difficult weather conditions, the department again installed four new detection stations, so completing the network of thirteen scintillators detectors planned at the origin of the project.
Pierre Auger Observatory
For the program of R&D "RAuger" on the radio detection of cosmic rays, three devices of autonomous radio detection were developed and installed on the site in Argentina, in association with Subatech, Nantes. The SDI made an important contribution for this activity by developing the power supply part by solar panels and batteries, as well as the mechanical supportof the set.
We also took in charge the part transport and logistics of the whole device and actively participated in its on site implementation in a first mission in 2006 then its upgrade in the second mission in 2007.
