As a technique that is dedicated to high-resolution studies, WD-XRF used to compromise on two levels: scanning modes and the inability to perform in-situ measurements. However, the photon-counting detector MYTHEN made these limitations less severe. Its small strips enabled excellent resolution, while the combination of its sensor size and its frame rate allowed a wider portion of the spectrum to be collected repeatedly in a single shot.
Now, synchrotron spectroscopists can look forward to new developments. MYTHEN2 is vacuum-compatible and runs at 1 kHz, while the new area detector EIGER2 offers exciting features in its tiny pixels: continuous readout and two thresholds.
In laboratory spectrometers, the wide MYTHEN2 detectors require no scanning motors to collect the spectrum. With these detectors’ wide coverage, it is possible to take in-situ measurements for elements from 4-40 keV, with an energy resolution down to 2 eV. New developments include optional vacuum compatibility for both MYTHEN2 and EIGER2.
- Achieve high resolution with small pixel and strip sizes.
- Detect weak signals with a high dynamic range and high efficiency for a wide range of X-ray energies.
- Take dynamic measurements with large detectors that offer a high frame rate and fast readout.
WD-XRF at Synchrotron Sources
- Make use of flexible experiment geometries with multi-modular MYTHEN2 systems that have different sensor thicknesses and a frame rate of 1 kHz.
- Take scanning measurements with continuous readout (EIGER2) and a frame rate up to 2 kHz.
- Suppress cosmics with the second energy threshold (EIGER2).
