WG1.1 Detectors

WG1.1 focuses on the development, calibration, integration and operation of detectors for synchrotron and XFEL sources. The developments are driven by the requirements of the end-stations at the facilities.

The main goal is to improve the scientific capabilities of the facilities and to enable more and better science.

In addition, WG1.1 tries to improve the operation and development of detectors at the facilities by exchange of information between the members and identification of shortcomings of current detectors and of future needs.

There are several ongoing formal and informal collaborations between the WG1.1 groups ranging from common beamtimes to joint detector developments.

An example of a common detector development is the LEAPS-INNOV project, where an energy-dispersive germanium detector was developed jointly by several detector groups in LEAPS. Currently, two prototype detectors have been built and are characterised by different European facilities.

The next larger project will be LEAPS TECH, targeting sensors for low (<2 keV) and high (>20 keV) photon energies. This enables large-area, high-frame-rate hybrid detectors in these energy ranges.

Currently, the main activities are finishing the development of LEAPS INNOV and preparing LEAPS TECH-ROAD.

In addition, there are several ongoing developments at the LEAPS facilities:

• Matterhorn, a new single-photon counting detector optimised for high count rates at 4^th generation synchrotrons (PSI)
• 2 BM, a burst-mode optimised version of the Jungfrau detector (PSI and EUXFEL)
• LGAD sensor development for low photon energies
• Percival, a CMOS-based detector targeting low photon energies at synchrotrons and XFELs
• Cordia, a high-frame-rate dynamic gain switching charge-integrating detector for synchrotrons and XFELs (DESY)
• Coupling of microchannel plates to pixelated readout ASICs for time-of-flight experiments
