Performance of a Ge 200-strip detector for inelastic X-ray scattering studies

Electron momentum-space densities of Li metal: A high-resolution Compton-scattering study

“…Synchrotron x-rays from the HARWI-Wiggler 2 of the DORIS storage ring are monochromatized by a Si ͑511͒ double crystal to 31 keV, and sagittally focused to a spot of 8ϫ8 mm 2 on the sample. Radiation scattered by ϭ155°is energy analyzed by means of a cylindrically bent Si͑400͒ Cauchois-type crystal, so that the complete spectrum can be recorded simultaneously by a position-sensitive Ge-200-strip detector 29 ͑strip width 200 m, strip distance 40 m͒, where each strip is connected with its own chain of preamplifier and amplifier.…”

5 New Generation of Gamma-Detector Arrays

“…Since electron-hole pairs created within the volume of the detector will travel along electric field lines to the corresponding electrode segment, a signal will only be derived from those segments that have collected an appreciable number of charge carriers [41]. This technique has been successfully used to produce position-sensitive planar Ge detectors [41,59,60]. Also segmented coaxial p-type Ge detectors have previously been produced but the segmentation of coaxial η-type Ge detectors became possible only recently.…”

Performance of the Compton Spectrometer at HARWI/HASYLAB

“…Figure 2 a shows the raw data of a [100] Si Compton profile (sample thickness 1 mm), where the data are only corrected channelwise for the variation of the individual strip efficiency of the PSD as described in detail in [8]. We found in the whole Compton profile a count rate of 200 counts s _1 with the storage ring working at 3.7 GeV and 60 mA.…”

“…The energy resolution is mainly determined by the 250 pm linear resolution of the PSD, which is a Ge detector with 200 independently working strips, each 200 pm wide and 250 pm apart, where each strip is connected with a complete chain of preamplifier, amplifier and discriminator as described in detail elsewhere [8]. For a 1 mm thick Si sample the count rate within the whole Compton profile is calculated to be 240 s _1 .…”
