The DSSC (DEPFET Sensor with Signal Compression) is a new instrument with non-linear compression of the input signal and with parallel signal processing (filtering, linear amplification, and 8/9-bit digitization) for all pixels. The DSSC will serve as ultra-fast 2d megapixel imaging detector at the European XFEL (X-ray Free Electron Laser) currently under construction in Hamburg, Germany. The DSSC...
The DSSC (DEPFET Sensor with Signal Compression) is a new instrument with non-linear compression of the input signal in the sensor and with parallel signal processing (filtering, linear amplification, and digitization) for all pixels. The design goal is to achieve at the same time single photon detection and high dynamic range, both for photon energies down to 0.5 keV and read-out speeds up to 4.5...
The DSSC collaboration is developing an instrument for the detection of synchrotron X-rays (E >; 0.5 keV) at XFEL. The hexagonal pixels of a DEPFET based sensor with integrated signal compression will be read out by bump-bonded pixel readout ASICs. Each ASIC will have 64 × 64 pixel channels of 236 × 204 μm2 area, each one containing a low-noise (<; 50 e-) amplification of the DEPFET signal,...
The European XFEL will have a burst rate of up to 5 MHz arranged in bunch trains each comprising up to 3000 pulses. The inter bunch train rate will be 10 Hz. The pixel readout of the DSSC (DEPFET Sensor with Signal Compression) foreseen for this machine will immediately digitize all analogue charges. The digital data is then stored locally within the pixels before it is read out. In order to accumulate...
