SRAM Field Programmable Gate Arrays (FPGAs) are beginning to be considered as viable solutions for particle physics experiments and well space applications. This paper summarise some of the radiation hardness measurements done on KINTEX-7 FPGA by our group using different beams like: protons, X-Rays ion beams.

This paper presents the irradiation and measurement analysis for a commercial antifuse Field Programmable Gate Array (FPGA) from Microsemi's Axcelerator family, part number AX250. Following proton X-ray beam irradiation, at very high dose rate above 1krad/s, total ionizing (TID) first effects were visible around 260 krad (SiO 2), this threshold value increases lower radiation rates. We expect most space accelerator applications that will be least several Mrads, or even FPGA might never reach...
