Abstract

A single event effect testing device based on a laser accelerator comprises a femtosecond laser device, a laser transmission system, a laser focusing system, an ion acceleration system, an ion beam shaping focusing system, a single event effect testing system and a vacuum target chamber system. Laser pulses generated by the femtosecond laser device are focused on an acceleration target of the ionacceleration system to generate a high-energy ion beam after passing through the laser transmission and focusing system, the ion beam shaping and focusing system is used for shaping and focusing the ion beam, the ion beam is transmitted to the single event effect testing system, and single event effect testing is achieved. Laser-driven accelerated ions are applied to the field of single event effect testing, and the device has the advantages of being table-type, flexible in direction adjustment, rich in particle variety, wide in energy spectrum, controllable in energy and the like, and can beapplied to space radiation environment simulation and the like.

Description

technical field [0001] The invention relates to the fields of laser plasma action and single-event effect, in particular to a single-event effect testing device based on a laser accelerator. Background technique [0002] Galactic cosmic rays, solar cosmic rays, and high-energy particles in the Earth's radiation belt are incident on electronic devices, and interact with the device to generate electron-hole pairs or atomic displacement damage, causing radiation effects on the device. The single event effect is a common radiation effect. At present, the experimental research of single event effect mainly adopts two ways: space loading and ground simulation. The space carrying method is to put the equipment dedicated to the study of single event effects on the spacecraft to test the radiation resistance characteristics of the device; the data is real and effective, but the experiment cost is high and the cycle is long. Ground simulation of single event effects mainly adopts tr...
