Speaker:     Dr. Mengqing Wu

Time:          13:00—14:00, May 25 

Location:    Room 1C-502, SIST Building

Host:          Prof. Yang Yang


DESY is one of the world’s leading accelerator centres and a member of the Helmholtz Association. DESY test beam facility operates three beam lines providing electron/position with energies from 1 to 6 GeV. Two of the three beam lines are equipped with an EUDET-type telescope based on the fine pitch Mimosa26 pixel sensor, requiring by ~70% users.According to the test beam user community, a task to improve the DESY test beam infras-tructure is assigned within the EU Horizen2020 AIDA-2020 project, including building up a new silicon telescope at the third beam line to address the need of momentum measurements

inside a 1T superconducting solenoid magnet, and an environmental slow control system to cover all the beam area. The new telescope is based on a 25μm pitch strip sensor of 10×10cm 2 , readout by two 1024-channel bumpbonded ASICs, and it is designed to provide a resolution better than 10μm in the bending direction, and a resolution better than 1mm along the magnetif field. This talk will give a brief introduction of the current DESY test beam infrastructure, with a focus on the R&D of the new telescope and the slow control system, and naturally a summary with perspectives will be given at the end.
