The Cornell-SLAC pixel array detector (CSpad) is a general-purpose integrating hybrid pixel x-ray camera developed for use at the Linear Coherent Light Source (LCLS) x-ray free electron laser at the SLAC National Accelerator Laboratory (SLAC). The detector has a full well capacity of about 2.5k photons in low-gain mode and a S/N of about 6 in high-gain mode. Its 2.3M pixels are read out at 120 Hz...
A GridPix detector is a gaseous detector capable of detecting single primary electrons from ionising particles. Such a detector consists of a pixel chip as active anode covered with a thin layer of silicon rich silicon nitride (SiRN) for protection against discharges. A layer of 8 µm SiRN, and according recent tests even 4 µm, is sufficient to protect against discharges. The effect of the thickness...
GridPix is a gas-filled detector with an aluminum mesh stretched 50 µm above the Timepix CMOS pixel chip. This defines a high electric field where gas amplification occurs. A feasibility study is currently ongoing at Nikhef for the application of the GridPix technology as a charge sensitive device in a dual phase noble gas Time Projection Chamber (TPC), within the framework of the DARWIN dark matter...
