Purchase of Detection System.

We investigate the interaction of extreme-ultraviolet radiation generated by the synchrotron light source ASTRID2 at Aarhus University with clusters and nanodroplets. The goal is explore the fundamental interaction processes of energetic radiation with condensed matter on the nanoscale (free clusters and nanoparticles). The central detection method is multiple coincidence imaging of electrons, ions, and photons.The electron-ion multiple coincidence imaging detection system based on one delay-line detector with hexagonal anode geometry and one imaging detector with a phosphor screen and a floating anode. The detector system by RoentDek Handels GmbH is the only (patented) system that provides electron and ion detection with high spatial and temporal resolution, high count rate, and with multiple hit capability. The latter is crucial for the planned experiments.

Minimum Requirements:

— Active area of the electron detector: 75mm diameter.

— MCPs have 70 % open area ratio (OAR) (QE > 60 %).

— MCP channel diameter < 13 µm.

— Local spatial resolution better than 100 µm FWHM for optimum conditions.

— Time-of-flight resolution better than 250 ps FWHM.

— spatial linearity of the detector better than 90 µm FWHM over 80 % of the detector surface.

— detector dead time equal to exactly 0 ns, if particles are spatially separated by more than 12 mm.

— reconstruction of events lost by the acquisition electronics due to dead-time effects.

— Preconfigured Software for the synchronous analysis of signals from 2 Detectors for coincidence measurements.

— One single, unsegmented anode.

— diagnostics / control of spatial resolution without calibration mask, just based on measured data to distinguish between resolution issues caused by the ion optics from those caused by the detector.

— Multiple coincidence imaging detection capability by combining one imaging detector with an active area with 75 mm diameter and one imaging detector with an active area with 40 mm diameter.

The results of the market research have shown that there is only one supplier that is able to meet our needs to carry out the projected research: RoentDek Handels GmbH. The offered detector system meets all requirements specified above.
