Hadronic showers develop an electromagnetic (from neutral mesons such as π 0 and η 0 ) and a non-electromagnetic component that are sampled with very different sensitivities (“non compensation”) in traditional calorimeters. The large fluctuations among the relative weight of the two components largely dominate the detector response resolution. Dual-readout calorimetry is a technique able to...
In the calorimetric particle detection, the hadronic energy resolution is considerably worse than the electromagnetic energy resolution. We understood the hadron shower physics and investigated the fundamental reasons to cause the poor performance in the measurement of hadron energy. Dual readout and compensation are two methods to remedy this problem. We evaluated these two methods and show...
The forward meson spectrometer, FMS, is the most forward electromagnetic calorimeter at the STAR detector at RHIC, covering rapidity from 2.5 to 4.1. It is an electromagnetic calorimeter comprised of 1254 lead-glass cells of two different types in content and size. The FMS was built primarily to unravel the novel spin effects seen in transversely polarized proton collisions. These effects...
Electromagnetic calorimeter (Ecal) is an important part of the Multi Purpose Detector (MPD) at the NICA collider. A shashlik-type electromagnetic calorimeter is selected as MPD ECal. The particular goals of the MPD ECal are to measure of spatial positions and energy of photons and electrons. Therefore, the energy resolution of the detector is the most important performance. The light yield is...
