2014, Advances in Space ResearchCitation Excerpt :One such detector module from KETEK, GmbH is shown in Fig. 5. In recent years, SDDs are fabricated with N-channel JFET in the silicon substrate which yields an improvement in energy resolution (Pinotti et al., 1993). These SDD modules provide good energy resolution when the SDD chip is cooled to temperature ⩽−35 °C (KETEK_VITUS_H30_Datasheet_Rev06.07.2009.pdf) which can be achieved by applying suitable power to the inbuilt Peltier cooler.

2008, Nuclear Instruments and Methods in Physics Research, Section B: Beam Interactions with Materials and AtomsCitation Excerpt :To fully exploit the benefit in terms of energy resolution and short shaping time arising from the low output capacitance typical of the SDD, both preamplifier input capacitance and stray capacitances of the connection between detector and preamplifier have to be kept as small as possible. This goal can be partially achieved by a very careful choice of the front-end transistor of the readout electronics and of its mounting on the detector, or nearly completely achieved by integrating the front-end transistor directly on the detector wafer [4–7]. The first solution takes advantage from the better performance of the discrete transistors, while the second solution takes advantage from a more effective reduction of the strays and from an easier approach to the ideal capacitive matching conditions (Cdetector = CFET).

2003, Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated EquipmentCitation Excerpt :In the following years the basic concept was simulated, modified and designed in detail [8,9]. N-channel JFET electronics were integrated in 1992 [10–12] and the first full working devices with a sensitive area of 3×1 cm2 were produced in 1993 [13,14]. The flight type monolithic large area detectors with an area of 6×6 cm2 were produced from 1995 to 1997, with a sufficiently high yield to equip the X-ray satellite mission XMM-Newton [15–19] with a defect free focal plane imager.
