Why Our Products Are Better
Vortex silicon drift X-ray detectors feature active areas between 30 mm2 and 80 mm2. Vortex detectors are produced from high purity silicon using state-of-the-art CMOS production technology. They feature excellent energy resolution (<130 eV FWHM at Mn Kα is typical) and a high count rate capability. At a very short peaking time of 0.1 µs, an output count rate of 900 kcps is achieved. A unique feature of these detectors is their ability to process high count rates with very small loss in energy resolution and minimal peak shift with count rate.
The Vortex is operated at near room temperature and cooled by a thermoelectric cooler (TEC) and can be cycled as frequently as needed without any degradation in detector performance. Cool down times are typically less than 2 minutes.
The Vortex X-ray spectroscopy systems include a detector unit and control box which includes power supplies for the detector, TEC and an optional digital pulse processor with our PI-SPEC Software.
The complete detector also contains a charge-sensitive preamplifier and temperature stabilization system, which eliminates concerns of varying ambient temperature.
