DIRC Options for SCTF — •Mustafa Schmidt1, Michael Düren1, Avetik Hayrapetyan1, Alexander Yu. Barnyakov2, and Sergey A. Kononov2 — 1II. Physikalisches Institut, Justus Liebig University Giessen — 2Budker Institute of Nuclear Physics, Novosibirsk
The proposed future e+e− collider Super Charm Tau Factory (SCTF) in Novosibirsk is designed to address fundamental questions in the field of particle and hadron physics. In order to guarantee an excellent PID at SCTF, two different types of Cherenkov counters are proposed as one possible design option. Both types, the barrel and the endcap counters use the principle of detection of internally reflected Cherenkov light (DIRC). The main purpose of these DIRCs is to separate charged pions and muons in the momentum range between 0.2 and 1.5 GeV/c by covering the full solid angle.
Two endcap DIRCs are proposed to be installed in the forward and backward regions. They consist of a thin fused silica radiator plate each, of attached focusing optics and sensors for photon detection. The concept of these detectors is based on existing models that have already been developed for the PANDA experiment at FAIR.
This talk will cover the ongoing simulation studies to optimize the performance of these detectors with respect to the Cherenkov angle resolution and timing information and the related readout systems. According to the actual plan, silicon photomultipliers (SiPMs) with a high granularity are going to be used to measure single Cherenkov photons.
