Three microchannel plate (MCP) detectors were developed for the European XFEL, enabling radiation detection across wide dynamic and wavelength ranges. These advanced detectors are now commissioned and ready for use in XFEL experiments.
Area of Science:
- Physics
- Instrumentation
- X-ray Science
Background:
- Microchannel plate (MCP) detectors are crucial for radiation detection in free-electron laser (FEL) facilities.
- The European X-ray Free-Electron Laser (XFEL) requires advanced detectors for its various beamlines.
Purpose of the Study:
- To develop and commission three MCP detectors for the SASE1, SASE2, and SASE3 lines at the European XFEL.
- To ensure these detectors can operate across a broad dynamic range and wavelength spectrum.
Main Methods:
- Development of three distinct MCP detectors tailored for SASE1, SASE2, and SASE3 beamlines.
- Integration of anodes and photodiodes for photon pulse energy measurement.
- Utilizing an MCP imager with a phosphor screen for photon beam imaging.
Main Results:
- MCP detectors for SASE1 and SASE3 have been successfully commissioned with XFEL beams.
- Calibration and initial measurements in multibunch mode have been performed using SASE1 and SASE3 detectors.
- The SASE2 MCP detector is installed, technically commissioned, and prepared for X-ray beam acceptance tests.
Conclusions:
- The developed MCP detectors are operational and meet the requirements for the European XFEL.
- The successful commissioning paves the way for advanced photon radiation measurements at the XFEL.
- All three MCP detectors are ready for full scientific utilization across the XFEL facility.

Calibration curves are used to understand the instrumental response to an analyte and predict the concentration in an unknown sample. Generally, a set of standard samples are made at various concentrations with a range than includes the unknown of interest and the instrumental response at each concentration is recorded. For more accuracy and to understand the error, the response at each concentration can be repeated so an error...
