1 mm Thick FAST SDD

A 1 mm thick detector is more sensitive to X-rays around 15 keV, an area where there are many elements of interest, Sn, Cd and rare earths. The new detectors will be of particular interest in µXRF, where focussed X-rays may not use the whole area of the detector. Then, the increased sensitivity of a thicker detector is of particular value. In other applications the thicker detector may actually prove cheaper than a larger area detector with the same sensitivity.
