Wavelength Dispersive X-ray Fluorescence (WD-XRF)

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.

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.

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.
