Abstract

With the first three years of the LHC running well underway, and luminosity upgrades expected towards the end of the decade, ATLAS and CMS are planning to upgrade their innermost tracking layers with the utmost radiation hard technologies. Chemical Vapour Deposition (CVD) diamond has been used extensively in beam conditions monitors as the innermost detectors in the highest radiation areas of BaBar, Belle, CDF and all LHC experiments. This material is now being considered as a sensor material for the innermost layer(s) of the upgraded trackers. Recently the CERN RD42 collaboration constructed, irradiated and tested polycrystalline and single-crystal CVD diamond sensors to the highest fluences expected at the innermost tracking layers of the HL-LHC. We present beam test results of chemical vapour deposition diamond to fluences in excess of 1016 protons/cm2 illustrating that both polycrystalline and single-crystal chemical vapour deposition diamonds follow a single damage curve. We briefly describe the performance of the diamond-based ATLAS beam monitoring devices and discuss plans for their upgrade to a diamond tracker during the 2013/14 LHC consolidation shut-down.
