چکیده
The luminosity upgrade of the large hadron collider (SLHC) at CERN will require the innermost layers of the vertex detectors to achieve excellent performances up to fluences of about 10 hadrons cm . New solid state detectors are currently being developed by the CERN RD50 collaboration. In this paper recent results on magnetic Czochralski, epitaxial, and oxygen-enriched silicon will be presented. The development of novel 3D and semi-3D devices will also be discussed. r 2006 Elsevier B.V. All rights reserved. PACS: 29.40.Wk; 29.40.Gx; 61.82.Fk

Recent developments of the CERN RD50 collaboration
The objective of the RD50 collaboration is to develop radiation hard semiconductor detectors for very high luminosity colliders, particularly to face the requirements of the possible upgrade of the large hadron collider (LHC) at CERN. Some of the RD50 most recent results about silicon detectors are reported in this paper, with special reference to: i) the progresses in the characterization of l...
متن کاملRD 50 Recent Results - Development of radiation hard sensors for SLHC
The need for radiation hard semiconductor detectors for the tracker regions in high energy physics experiments at a future high luminosity hadron collider, like the proposed LHC upgrade, has led to the formation of the CERN RD50 collaboration. The R&D directions of RD50 follow two paths: the optimization of radiation hard bulk materials (Material Engineering) and the development of new detector...
متن کاملRD50 value as the criterion for setting maximum admissible levels of occupational exposure to irritants in Poland.
The aim of this work is to analyse Maximum Admissible Concentration (MAC) values proposed for irritants by the Group of Experts for Chemical Agents in Poland, based on the RD50 value. In 1994-2004, MAC values for irritants based on the RD50 value were set for 17 chemicals. For the purpose of the analysis, 1/10 RD50, 1/100 RD50 and the MAC/RD50 ratio were calculated. The determined MAC values ar...
متن کاملSilicon Detectors for the sLHC - an Overview of Recent RD 50 Results
It is foreseen to significantly increase the luminosity of the Large Hadron Collider(LHC) at CERN around 2018 by upgrading the LHC towards the sLHC (Super-LHC). Due to the radiation damage to the silicon detectors used, the physics experiment will require new tracking detectors for sLHC operation. All-silicon central trackers are being studied in ATLAS, CMS and LHCb, with extremely radiation ha...
متن کاملDegradation of charge sharing after neutron irradiation in strip silicon detectors with different geometries
The aim of the CERN/RD50 collaboration is the improvement of the radiation tolerance of semiconductor detectors for future experiments at high-luminosity colliders. In the RD50 framework, evidence of enhanced signal charge in severely irradiated silicon detectors (diodes, segmented planar and 3D devices) was found. The underlying mechanism was labelled charge multiplication. This has been one o...
