Diamond Detectors in High Radiation Environments
| Abstract: |
Progress in experimental particle physics in the coming decade depends crucially upon the ability to carry out experiments at high energies and high luminosities. These two conditions imply that future experiments will take place in very high radiation areas. In order to perform these complex and perhaps expensive experiments new radiation hard technologies will have to be developed. Chemical Vapor Deposition (CVD) diamond is being developed as a radiation tolerant material for use very close to the interaction region where detectors may have to operate in extreme radiation conditions. During the past few years many CVD diamond devices have been manufactured and tested. As a detector for high radiation environments CVD diamond benefits substantially from its radiation hardness, very low leakage current, low dielectric constant, fast signal collection and ability to operate at room temperature. We will present the present state-of-the-art of polycrystalline CVD diamond and the latest results obtained from detectors constructed with this material. Recently a new type of diamond has been developed: single crystal CVD diamond which resolves many of the issues associated with polycrystalline material. We will also present recent results obtained from devices constructed from this new diamond material. Finally, we will discuss the use of diamond detectors in present and future experiments and their survivability in the highest radiation environments.

 Harris Kagan is a Professor of Physics at the Ohio State University. He received his Ph.D. from the University of Minnesota in the field of Experimental High Energy Physics. During his career he has carried out a broadly based research program on b, charm and tau physics as well as detector development and front end analog electronics. He is an APS fellow and is presently a member of the ATLAS and BaBar experiments. He was a co-proposer of the idea and has been a leading force in the development of diamond based detectors.
