Irradiation Facility For Single-Event Effect Studies At Beijing Hi-13 Tandem Accelerators

Irradiation facility for single-event effects (SEEs) experiments of space-borne microelectronic devices has been established at Beijing HI-13 tandem accelerator. Mono-energetic and uniformly-distributed accelerated beams over the certain area were obtained at the focal plane in Q3D magnetic spectrometer, and these beams have been extensively used in SEE ground testing. In order to study the mechanism pertinent to SEEs, a heavy-ion microbeam. irradiation test system has been developed utilizing a pinhole aperture to define the accelerator beam to microbeam. The performance of the irradiation system was tested by microbeam strike on a plastic track detector. The microbeam with the spot size of about 2.3 mu m x 3.5 mu m has been achieved by a micro-collimator with an opening area of about 2 mu m x 3 mu m.
