Title: Development of 3D diamond detectors for detector applications at ultra high luminosity facilities

Abstract

During this project our group has succeeded in producing and measuring a number of 3D diamond devices. We have worked with manufacturers and shown that poly-crystalline CVD (pCVD) diamond can be grown reliably with a 5% uniformity in industry. We have produced 3D diamond devices and scaled up the production technology from roughly 100 cells on a device to 4000 cells on a device. We have increased the column yield from 92% to 99%. We have reduced the cell size from our safe initial choice 150μm x 150μm cells to the HL-LHC size of 50μm x 50μm cells. We have reduced the column diameter from 6-10 μm to 2.6 μm. In beam tests we have quantified the amount of charge each 3D device yields for minimizing ionizing particles and compared this to that produced by a planar diamond device. Very recently, we produced the first 3D diamond pixel devices read out with both ATLAS and CMS pixel electronics, tested them in particle beams at CERN and PSI. Finally we have successfully tested the first irradiated 3Ddiamond device after a fluence of 3.5 x 10^15 800 MeV p/cm^2.
