Between November 29th and December 1st the LuxSpace Triton-X team joined ESA at CERN in Geneva to participate in a heavy ion radiation campaign to validate the operation of key software and hardware components and their resilience to radiation induced bit errors. The testing was carried out CERN’s second largest accelerator, the Super Proton Synchrotron (SPS), 6.9 km in circumference, now in use for injecting high intensity proton beams into the Large Hadron Collider (LHC). When the LHC is not being supplied with accelerated particles, the particles can be utilised for other purposes, such as component radiation testing. The advantage of higher energy levels in the GeV domain is that it removes the need for thinning or removing microelectronic packaging materials from the device under test, and several experiments can be placed in the particle beam simultaneously. A second proposal has been submitted for next year, in which the CERN complex will accelerate lead ions with similar energies and penetration and a higher ionization than that of the xenon beams used in 2017.
