Nuclear and Particle Physics – Charged Particle Tracking, Particle Identification and Calorimetry
Discoveries in particle physics rely on detectors that allow physicists to characterize particles and fields. It is important to identify particles and measure their energy, momentum, and their trajectories.  Modern charged particle trackers are based on semi-conductors (silicon) or gas filled detectors. In modern trackers many electrical signals must be read out from the detectors, often simultaneously, with low noise and at very high rate. The requirements of charged particle trackers are ideally met by integrated circuits. Ring image Cherenkov detectors (RICH) and transition radiation detectors (TRD) allow scientists to identify the type of charged particles. TRD and RICH detectors are important for discoveries and tests of the theoretical models. RICH and TRD are designed such that the charged particles emit light (photons) when they traverse the detector medium (often a gas). The RICH allows one to measure the diameter of ring images that are created from a few Cherenkov photons. IDEAS has designed integrated circuits for charged particle tracking detectors, RICH, TRD and calorimeters. The ASICs have been used in large-scale experiment (BELLE, PHOBOS, NOMAD, ALPHA, ATHENA, etc.). Integrated circuits are ideal for modern charged particle trackers. IDEAS designs the detector front-end electronics to make scientists achieve their goals.

Applications at Neutron Facilities
Neutrons can be produced in specialized research facilities, for example at the European Spallation Source (ESS).  The neutrons are directed at the sample to be investigated. The neutrons scatter at the samples’ atomic nuclei, which gives information about the position and movement of the atoms in the sample. The neutron detectors acquire timed images of many scattered neutrons. The neutron detectors enable snapshots of biological and chemical processes. The challenge is to build neutron detectors with high spatial resolution and high count rate capability. Integrated circuits from IDEAS are used for the front-end readout of neutron detectors.
