Elementary Particle Physics Seminar

Wednesday, April 27th 2016
Speaker: Maxim Titov, Saclay
Subject: Micro-Pattern Gas Detector Technologies for Physics Projects at the Energy, Intensity and Cosmic Frontiers

Improvements in detector technology often come from capitalizing on industrial progress. Advances are made with new insights; recent industrial developments in photo-lithography, microelectronics and printed circuits technique have opened the road for the production of micro-structured gaseous amplification devices: Microstrip Gas Chamber (MSGC), Gas Electron Multiplier (GEM) and Micro-mesh gaseous structure (Micromegas), followed by the thick-GEM (THGEM), resistive GEM (RETGEM), Micro-Pixel Gas Chamber (μ-PIC), and an integrated readout of gaseous detectors using solid-state pixel chips (InGrid). By using a pitch size of a few hundred micrometers, MPGD systems now offer operational stability, protection against discharges, radiation hardness, high-rate capability (> 1MHz/mm2), excellent spatial resolution (~30 mm), and a time resolution down to a few-hundred pico-second range. This talk will highlight recent MPGD technology advances and address numerous MPGD applications at the Energy, Intensity and Cosmic Frontiers.
