For the readout of the TRD sub-detector of the planned fixed-target CBM experiment at FAIR/GSI (Darmstadt, Germany), a new self-triggered amplification and digitization mixed-signal chip is being developed. The final ASIC will have 32-64 channels each composed of a low noise and power charge preamplifier, a 7-9 Bit pipeline ADC running at about 25 MSamples/s and some digital data processing units...
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 integration of PET and MR imaging requires a novel type of highly integrated PET detector. To cope with geometric constraints and MR compliance a very compact detector stack was built within the HYPERImage consortium. This allows a four side buttable detector module design with a low dead space in between. The scintillation light coming from a LYSO array is converted in a SiPM sensor tile with...
A novel signal processing concept for X-ray imaging with directly converting pixelated semiconductor sensors is presented. The novelty of this approach compared to existing concepts is the combination of charge integration and single photon counting in every single pixel. Simultaneous operation of both signal processing chains extends the dynamic range beyond the limits of the individual schemes and...
