Embodiment Construction

[0022] see figure 1 , The technical solution of the present invention includes screening probes with SOI structure, adjusting and confirming detector parameters, obtaining and calibrating the detector response under the radiation source, and obtaining the relationship between the detector response and the dose of the radiation source. Specifically, the flow of the total ionization dose detection method provided by the present invention is as follows:

[0023] (1) Screen the probes with SOI structure: conduct a thorough test on the screened probes, place the probes in a radiation source that can cause ionizing radiation damage, and obtain the threshold voltage drift (that is, obtain the I-V characteristics) through the shift test to confirm the Probe alignment is sensitive to ionization damage. Among them, the threshold voltage drift is collected offline with a semiconductor test system keithley 4200.

[0024] (2) Build the detector: the detector consists of two PCB boards, o...

Description

technical field [0001] The invention relates to the technical field of radiation environment detection, and relates to a total ionization dose detection system and method based on an SOI structure. Background technique [0002] In the space environment, various charged particles and their secondary rays captured by the Milky Way, the solar system, and the earth's magnetic field interact with spacecraft and loads to generate a large amount of secondary radiation, causing radiation damage to materials, components, and electronic systems of spacecraft. It leads to failure or failure of various payloads of the spacecraft, which seriously affects the reliability and operation life of the spacecraft. Therefore, it is very important to study the absorbed dose of electronic components and electronic systems that cause radiation damage in space charged particle radiation and the radiation environment inside and outside the planet, and measuring the space radiation environment is an i...
