The SCT detector concept

The SCT detector concept

Super cτ (SCT) factory is an electron-positron collider operating in the range of center-of-mass (c.m.) energies from 2 to 5 ÷ 6 GeV with a high luminosity of about 1035 cm−2 s−1. In this energy range practically all states with charm can be produced including charmonium-mesons and charmed baryons comprising one c quark. Because of its extremely high luminosity such a collider will be a copious source of charmed particles and τ leptons. Experiments at this setup are assumed to be sensitive to effects of new physics beyond the Standard Model. Investigations to be carried out at the Super-Charm-Tau factory will supplement experiments at flavour factories in Japan, China and Italy.

The SCT detector comprises a beryllium vacuum chamber, a vertex detector (VD), a drift chamber (DC), a particle identification system based on focusing aerogel RICH (FARICH) and an electromagnetic calorimeter based on pure CsI crystals.  These systems are placed in a superconducting solenoid with a 1 Tesla field. The most outer layer is the iron yoke with built-in muon detectors.
