Application of PPAC for Homogeneity Analysis on the SEE Ground-test

Nuclear track detector cannot get the beam profile promptly. A uniformity measurement system based on the Position sensitive parallel plate avalanche detector (PPAC) was built to fulfil the homogeneity analysis in real time during the SEE test. Here its construction and principle, the method of analysis and the result of beam test are described. To validate the result of PPAC, a PET film was synchronously irradiated before the PPAC. In comparison with the obtained results of PET films observation, the uniformity value from the PPAC has an estimated maximum error of 5%.The PPAC has about 1 mm position resolution and 50 mm x 50 mm sensitive area. Which can satisfy the
    requirement of uniformity analysis on SEEs test by accelerator irradiation.
