Description

At present most experiments at the CERN Large Hadron Collider (LHC)
are planning upgrades in the next 5-10 years for their innermost
tracking layers as well as luminosity monitors to be able to take data
as the luminosity increases and CERN moves toward the High Luminosity-LHC
(HL-LHC). These upgrades will most likely require more radiation
tolerant technologies than exist today. As a result this is one area of
intense research. Chemical Vapor Deposition (CVD) diamond is one such
technology. CVD diamond has been used extensively in beam condition
monitors as the innermost detectors in the highest radiation areas of
BaBar, Belle, CDF and all LHC experiments. This talk will describe the
recent radiation tolerance measurments of the highest quality
polycrystalline CVD material for a range of proton energies, pions and
neutrons obtained with this material with the goal of elucidating the
issues that should be addressed for future diamond based detectors. The
talk will also discuss the new results on the evolution of various
semiconductor parameters as a function of dose.
