Vladimir Eremin is an experienced experimentalist in physics of semiconductors and semiconductor devices. The field of his activity is research and development of semiconductor detectors based on silicon that are designed for high-energy physics, radiation detection and imaging. Recent investigations are related mainly to the development of radiation-hard semiconductor detectors for the experiments at the Large Hadron Collider at CERN, Switzerland, and FAIR program at GSI, Germany. V. Eremin participates in the CERN R&D collaborations (RD50 and earlier RD48). He was a team leader of the Ioffe Institute group in CERN-RD39 collaboration and in R&D on edgeless silicon detectors for CERN-TOTEM collaboration experiment. His current activity is developing fast timing detectors for the TOF diagnostics of heavy ions at the new facility at GSI.
As a principal investigator, Vladimir Eremin was involved in scientific projects supported by Russian funds and institution.
The number of his publications in referred journals is about 170 and of presentation at the conferences and workshops is about 85. Last years he is invited for reviewing the manuscripts in the main journals in the field of semiconductor detectors Nuclear Instruments and Methods in Physics Research, IEEE Transactions on Nuclear Science, Journal of instrumentation, Journal of applied physics, and several national journals.
Since 1993 he is a leader of the Silicon Detector group in the Ioffe Institute, which collaborates with CERN, GSI, Brookhaven National Laboratory, USA (1992-2010), and Helsinki institute of physics in the field of R&D in semiconductor detectors for the experiments in high-energy physics.
报告摘要(Abstract):
The increased LHC luminosity as well as maximal particle energy require more precise data on the intensity of radiation field at the magnet coils of collider. For that the radiation sensors must be placed in the proximity of the coils, which minimizes the fraction of debris in beam loss monitoring. Silicon sensors were chosen as one of the candidates and the related R&D was started seven years ago jointly by CERN BE-BI-BL group and RD39 collaboration and Ioffe institute. The sensors developed at the Ioffe Institute and in situ tested at temperatures 1.9 and 4.3 K showed reproducible characteristics and gave new findings in the detector physics. In the talk the problem, selected data and related physics will be presented which will give a basic knowledge on silicon detectors operation at cryogenic environment.
