Abstract

Determining the threshold values in case of multiple bit upsets based on impinging particles flux density is an urgent problem for radiation-hardened electronics designers. To deal with such class of problems, a special three-beam pulsed electron linac called SPRUT was developed. The linac is used to generate an electron beam with electron energy of 5–7 MeV, current of approx. 1 A, pulse width of 1–12 μs, and repetition rate up to 1 Hz. Total electron beam, not less than 20 mm in diameter, with high electron flux density is generated behind the exit foil. Configuration and position of the combined beams can be adjusted to ensure the irradiation area non-uniformity not worse than 30%. The paper describes the SPRUT linac design and operating principle, as well as the methods used to measure its characteristics and the results obtained thereby, it helps studying the possibilities to generate the radiation field with certain characteristics.

电子直线加速器SPRUT研究辐射硬度

对于抗辐射电子设计人员来说，根据碰撞粒子的通量密度确定多次钻头扰动的阈值是一个迫切需要解决的问题。为了解决这类问题，研制了一种特殊的三束脉冲电子直线加速器SPRUT。该直线加速器用于产生电子能量为5 - 7mev的电子束，电流约为。1 A，脉冲宽度1 ~ 12 μs，重复频率可达1hz。出口箔后产生的总电子束直径不小于20mm，电子流密度高。组合光束的配置和位置可调节，保证辐照区域不均匀性不大于30%。本文介绍了SPRUT直线加速器的设计和工作原理，以及测量其特性的方法和得到的结果，有助于研究产生具有一定特性的辐射场的可能性。
