The ROSE Collaboration (CERN - RD48)

  
The objectives of the collaboration are:

  • The development of radiation hard silicon detectors that can operate beyond the limits of present devices and that ensure guaranteed operation for the whole lifetime of the LHC experimental programme.
  • The outline of recommendations to experiments on the optimum silicon for detectors and quality control procedures required to ensure optimal radiation tolerance.

The ROSE Collaboration currently consists of 38 international groups working on detectors for particle physics experiments at the LHC. The Collaboration benefits from the very valuable input of solid state physicists and the expertise of silicon manufacturers, who are also members of RD48. In addition the close involvement of Canberra, CNM, Micron and SINTEF is shown through their "Associated Company" status. Inputs are also acknowledged from the European Space Agency, IMEC, Belgium and the MPI Semiconductor Laboratory in Munich all of which are cooperating via an "Observer" status. Work at ITE and ITME (both RD48 members) has been vital for the rapid development, production and processing of various materials. More recently collaboration with ITME has resulted in high quality material characterisation. Finally the RD48 technique for Oxygen enrichment had been successfully transferred to CiS (Germany), Micron (Great Britain), SINTEF (Norway) and ST-Microelectronics (Italy). These manufacturers have produced dedicated ROSE test detectors and full scale detector prototypes for LHC experimental groups on oxygenated silicon.

The Collaboration formed following the First Workshop on Radiation Hardening of Silicon Detectors at CERN in October 1995. The proposal was approved by the LHCC in June 1996. The Second Workshop was held at CERN in February 1997, the third one at DESY in February 1998 and the fourth at CERN in December 1998 followed by a Meeting in June 1999. The Fifth Workshop  will be held shortly in March 2000.
