The proton irradiation facility for Single-Event effect testing in CIAE

The proton radiation facility is built at an irradiation terminal of a 100-MeV cyclotron accelerator in the China Institute of Atomic Energy (CIAE). It is mainly used for testing the single-event effect of electronic devices. The part and function of the proton beamline for radiation effects research are introduced. Many detectors and techniques are used to accomplish accurate and reliable dosimetry and characterization of the proton beam. The results of beam characterization such as transmission, energy, lateral profile, and flux are reported. A typical monitoring and measuring system consist of a secondary electron emission monitor (SEM) working in a transmission mode and Faraday cup (FC). A cross-checking method of proton flux accuracy by FC and scintillation detector (SC) is established. The application of the reference single-event upset (SEU) monitor for the characterization of proton beams at different facilities is described. The SEU cross-section of the Reference SEU Monitor has confirmed the flux detection accuracy at CIAE.
