Paper Abstract

A micro-channel plate (MCP) transmissivity is calibrated using the 3B3 medium energy X-ray beamline (from 2.0 to 5.5keV) on Beijing Synchrotron Radiation Facility (BSRF). MCP transmissivity near the two ends of low-energy 2.0keV and high-energy 5.5keV is higher than the middle part. We calculate reflectivity and transmission in the pores array of MCP respectively, and take the experiment result into account synthetically. It uncovers that the grazing incident X-ray in pores results in the total reflection, and the reflectivity rises as the X-ray energy decreases, which successfully explains the peculiar phenomena of the high transmissivity in low energy.
