7-ch Si-Drift Detector Module
7-ch Si-Drift Detector Module Project Goal:Development and realization of a compact 7-ch Si-drift detector module.Project Status:Finished in 2007 |
The Peltier-cooled 7-cell SDD module comprises a sensor with 7 x 7-mm² active area, an ASIC for amplification, shaping and detection, storage, and derandomized readout of signal pulses in parallel, and amplifiers for line driving.The compactness and hexagonal shape of the module with a wrench size of 16 mm allow very short distances to the specimen and flexible multi-module arrangements. At a shaper peaking time of 190 ns and an integration time of 450 ns an electronic rms noise of ~11 electrons was achieved. When operated at 7°C, FWHM line widths around 260 eV and 460 eV (Cu-Kα) were obtained at low rates and at sum-count rates of 1.7 MHz, respectively. The module is in use at synchrotron beamlines for fast X-ray spectroscopy experiments.
