CBM

The Compressed Baryonic Matter (CBM) experiment is a stationary target spectrometer with hadron and leptonidentification. It is under construction at the Facility for Antiproton and Ion Research (FAIR) that is beingrealized next to the GSI grounds in Darmstadt, Germany. [...]

This work reviews various methods used to minimize the probability of discharge occurrence in MPGDs or to mitigate the effect of spark discharges on the detector system. These include techniques that can reduce the probability that the fundamental discharge limits of MPGD structures are reached during detector operation, methods based on the HV scheme optimization, or the implementation of resistive electrodes to enhance local discharge quenching capabilities in an amplification structure. [...]

In this work we probe the QCD Anderson transition by studying spectral distributions of the massless overlap operator on gauge configurations created by the twisted mass at finite temperature collaboration (tmfT) with 2+1+1 flavors of dynamical quarks and the Iwasaki gauge action. We assess finite-size and discretization effects by considering two different lattice spacings and several physical volumes, and mimic the approach to the continuum limit through stereographic projection.

The Compressed Baryonic Matter (CBM) is one of the experimental pillars at the Facility forAntiproton and Ion Research (FAIR). The Silicon Tracking System (STS) is the central detectorfor track reconstruction and momentum measurement. [...]

In this study, we investigate the impact of humidity on the performance of a THGEM operated with an Ar-CO$_2$ gas mixture. The water content is introduced in a range of 0–4000 ppmV. [...]

Spark-Less-Amplification-Microstructures are a new type of gaseous detectors, which should allow overcoming the discharge limitations of the current MPGD technologies. Preliminary studies revealed that sparks usually appear in the narrow region of the amplification gap, where the electric field lines are parallel to each other. [...]
