摘要：

An Electron-Tubes-LTD 129EM electron multiplier tube has been modified to act as a detector of soft x-rays. The first dynode was coated with 100nm of CsI and the assembly was mounted in a small vacuum chamber with 100nm thick silicon nitride entrance window. Initial tests show the detector is linear up to an input flux of similar to 1MHz on a synchrotron source and has proved effective in providing pulse height discrimination when used on a pulsed laser plasma source.
