Micropattern gas detectors (MPGD)
Silvia Dalla Torre
MicroPattern Gas Detectors (MPGD) are made possible by the development of photolithographic techniques. They have been introduced in 1988 when the first architecture, namely the MicroStrip Gas Chamber (MSGC) [A. Oed, Nucl. Instrum. Meth. A 263 (1988) 351]was proposed, and evolved in the following year by the concepts of MICROMEGAS [Y. Giomataris, P. Rebourgeard, J. Robert and G. Charpak, Nucl. Instrum. Meth. A 376 (1996) 29] and GEMs [F. Sauli, Nucl. Instrum. Meth. A 386 (1997) 531]. In the recent years, they are experiencing continuous evolution and performance progress: following the first large-scale application at the COMPASS experiment, nowadays they are mature for large scale applications in the major LHC experiments. Moreover, the progress in the field driven by the usage in the HEP sector is opening the way to opportunities of applications in other scientific domains, in particular at neutron facilities and beyond science in sectors of social relevance (medical applications, homeland security, environmental monitoring). The lecture illustrates the principles of the main detectors, the consolidation of the techniques, the novel MPGD architectures and the main field of applications in HEP, scientific research and beyond .

Silvia Dalla Torre is a senior scientist at INFN Trieste, where she is presently the Director of the INFN Sezione di Trieste. Her main research interest concerns hadron physics and, in particular, the nucleon spin structure at the CERN SPS, with the COMPASS experiment. Her main expertise is in the field of detectors for HEP and she has coordinated the COMPASS RICH project, that resulted in a large-size, large-acceptance focusing RICH with gas radiator. Her current research activity focuses on the design, construction and implementation of novel single photon detectors based on MPGDs to upgrade the COMPASS RICH. Silvia Dalla Torre is author of more than 150 articles in international journals with referee. |

She is the chairperson of the Collaboration Board of the RD51 Technological Collaboration devoted to MPGDs. She has been members of scientific committees: SPSC (CERN), CSN I (INFN), LHCC(CERN). She is, on regular basis, referee for the journals NUCLEAR INSTRUMENTS & METHODS A and JOURNAL OF INSTRUMENTATION (JINST) and JINST editor since 1 October 2013. She has been referee of the experiments OPERA (for SPSC), ATLAS (for INFN), LHCb and TOTEM (for LHCC). She is, on regular basis, member of the Scientific Advisory Committees in conferences dedicated to nuclear and particle instrumentation and she has been Chairperson of the Local Organising Committee of RICH 2007 (Trieste, 2007) and editor of the workshop proceedings.
Silvia Dalla Torre is a member of the Scientific Committee of the IV Seminario Nazionale Rivelatori Innovativi, as well as of the previous issues of the seminar.
