D3: Gaseous Detector R&D
- Rui de Oliveira (CERN)
The Budker Institute of Nuclear Physics is actively developing the Super Charm-Tau Factory (SCTF) project, which is a mega-science class facility that will be used to study the decays of rare c-quarks and tau-leptons in Sarov, Russia. A new drift chamber to the SCTF detector is proposed consisting of 41 layers of hexagonal cells with an average radius of 7 mm in the He/C3H8 gas mixture. The...
In this contribution, we present a development of resistive Micromegas (MM) technology to reach stable and efficient operation up to particle fluxes of 10 MHz/cm2. This can be achieved with a pixelized detector using readout pads of a few mm2 area, significantly reducing the occupancy of the readout elements. In the most recent prototypes (exploiting double DLC layer), the resistive layer is...
Resistive Plate Chamber (RPC) detectors, employed in the muon systems of CERN LHC experiments, are operated with gas mixtures containing C2H2F4 (R-134a) and SF6, both greenhouse gases (GHGs) with a high global warming potential (GWP). Among strategies developed by CERN Gas Team to reduce GHG emissions, one branch is focused on studying alternative gas mixtures and one on recuperating gases...
This work explores a technique for extracting the position of particle along the direction of a pickup strip, in a large area single-gap Resistive Plate Chamber (RPC), by measuring the timing-difference from the two ends of the strip. Using precise time-difference measurement, the position can be obtained more precisely than the conventional x-y strip readout with the same number of...
