Abstract

In the ALICE Time Projection Chamber [1] TPC at CERN the front end electronics will be located about 3 meters from the interaction point and will therefore be exposed to radiation generated by the particle collisions. Consequently this can lead to single event upsets in sequential logic or in the configuration RAM of the FPGA. Irradiation tests have therefore been developed and carried out using the cyclotron in the physics department at the University of Oslo in Norway. The objective of the test experiment was to measure the radiation tolerance of a SRAM-based field programmable gate array (FPGA). This paper presents an overview of the irradiation tests, the latest test results and will address further investigation into hardening techniques.
