The Cooling Storage Ring of the Heavy Ion Research Facility in Lanzhou (HIRFL-CSR) is constructed to study nuclear physics, atomic physics, inter-disciplinary science and relative applications. The internal target is built on the experiment ring of the HIRFL-CSR for high precision measurements. Due to the high spatial resolution, a Monolithic Active Pixel Sensor (MAPS) based pixel detector is...
During the long shutdown of LHC (2019/2020), the complete LHCb tracking system will be replaced to cope with the increased luminosity and trigger less read-out scheme. A large area (300m^2) scintillating fibre tracker (SciFi) with more than 500K channels and 250μm readout pitch is under construction. The silicon photomultiplier technology employed for the read-out provides high photon...
Silicon photomultipliers (SiPMs), also known as multi-pixel photon counters (MPPCs), represent an alternative solution that to a large extent combines the advantages of PMTs and APDs. They have high gain, low bias voltage, excellent timing properties and are insensitive to magnetic fields. SiPMs perhaps are the best readout choice for advanced positron emission tomography (PET) systems, such...
An x-ray imaging mixed-mode pixel array detector (MM-PAD) coupled to a $750\, \mu m$ thick CdTe sensor is described. The detector comprises a 2$\times$3 tiled array of individual 128$\times$128 pixel ASICs coupled at the pixel level to CdTe sensor. The CdTe sensor significantly improves the detection efficiency for high-energy x-rays when compared to silicon sensors. The detector is capable of...
