Synchrotron Radiation Test Validations of European XFEL MCP-based Detectors at DORIS Beamline BW1
EuXFEL staff
Radiation detectors based on micro channel plates (MCP) are planned for installation at the European XFEL. Main purpose of these detectors is searching a signature of lasing and further fine tuning of the FEL process. Detectors operate in a wide dynamic range from the level of spontaneous emission to the saturation level (between a few nJ and 25 mJ), and in a wide wavelength range from 0.05 nm to 0.4 nm for SASE1 and SASE2, and from 0.4 nm to 4.43 nm for SASE3. Photon pulse energies are measured with traditional MCP with anode and with photodiode. The photon beam image is measured by MCP imager with phosphor screen anode. The SR tests validation of the MCP-based detector applied for XFEL SASE1 and SASE2 were performed at the DORIS beamline BW1 and photon energy of 8.5-12.4 keV. The absolute measurem ents of a photon pulse energy of 0.03 nJ and larger for hard X-ray radiation were performed with application of MCP and photodiode detectors. Pulse-to-pulse photon energy measurements with MCPs and a JINR silicon photo detector were done with 192 ns and 96 ns repetition intervals. The SR beam imaging measurement at X-ray irradiation was performed at test validation experiments.
