    A model is presented which allows the calculation of the electron induced degradation in heteroface AlGaAs-GaAs solar cells. The temperature dependence of the semiconductor parameters is also included. The radiation effects have been modeled by the minority carrier lifetime degradation. The best agreement with experimental results is obtained when the recombination center capture cross section in ... View full abstract»

    An intelligent interface for readout of a high speed (100 MHz), multichannel Flash-ADC System [1] is described. 3072 FADC channels are controlled and read by a system of 34 microprocessors M68000 placed at two different hierarchical levels. In addition to the readout itself, the processors perform a detailed pulse shape analysis neccessary for a compact and manageable data format. The purpose of t... View full abstract»

    A fast closing valve (FCV) system has been built to protect the vacuum of the electron storage ring against sudden vacuum failures during synchrotron radiation experiments. An electronic control detects the failure, and closes a 140 × 17 mm aperture within 32 ms with a guillotine blade driven by pneumatic pressure. This pressure is gated by a magnetic valve which is operated by an explosive charg... View full abstract»

  • The Use of an Optimized Coincidence Time Window in BGO Positron Cameras

    In a positron emission tomograph the ratio of true-to-random coincidences decreases at elevated count rates, thereby causing a degraded image. Efficiency simulations of a representative sample configuration show that for brain cameras, the high sensitivity range of BGO systems can be extended by using an optimized coincidence time window. The window width is then chosen to optimize the signal-to-n... View full abstract»
