Paper Abstract

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 100 nm of CsI and the assembly was mounted in a small vacuum chamber with 100 nm thick silicon nitride entrance window. Initial tests show the detector is linear up to an input flux of approximately 1MHz on a synchrotron source and has proved effective in providing pulse height discrimination when used on a pulsed laser plasma source.
