Component and System Testing at the CHARM Mixed-Field Facility – CERN

Component and System Testing at the CHARM Mixed-Field Facility

Talk summary: Electronics systems designed for applications in high radiation environments, such as space missions, high energy accelerators and avionics, are subject to a radiation qualification process at component level which is often time consuming and expensive.

The new CERN High energy AcceleRator Mixed Field facility (CHARM) allows to test several single components, as well as more complex devices, at different locations, characterized by particle spectra representative of the high- and low-altitude atmospheric, particle accelerator and ground environments.

Single Events and TID effects are evaluated through the energy deposition in a certain Sensitive Volume in a broad range of energies (meV to GeV), not often available in other test facilities. COTS components and full systems designed for cryogenics, power converters, radiation monitoring and Nanosatellite applications were successfully tested in a mixed field dominated by Highly Energetic Hadrons.

This radiation qualification process proved to be effective in terms of budget, facility access and time constraints.

Raffaello Secondo received his Master of Science in Electronics Engineering at the University of
Genova in 2009. He has worked for 3 years as a controls engineer and beam physicist at the
Lawrence Berkeley Laboratory. He joined CERN in 2012 as a Software and Hardware design
engineer in the Equipment Controls and Electronics section, mainly working on setup
development for radiation tests, design of radiation tolerant systems and radiation hardness
assurance of COTS components. Since 2014 he is enrolled in a Ph.D program with the
University of Montpellier at CERN, his present focus is the development of the CELESTA
Nanosatellite Mission Payload and the optimization of the CERN Radiation Monitoring Systems.
