Making of 3D diamond detectors

Intense laser pulses write graphitic electrodes in diamond in order to produce 3D pixel sensors optimised for timing applications at future hadron colliders. Just published in Instruments.

Tracking detectors at future high luminosity hadron colliders will need to stand unprecedented levels of radiation as well as to efficiently reconstruct a huge number of tracks. Diamond 3D pixel sensors optimised
for timing applications provide an appealing solution to the above problems as the 3D geometry enhances the already outstanding radiation hardness and allows to exploit the excellent timing properties of diamond. We report here the first full timing characterisation of 3D diamond sensors fabricated by electrode laser graphitisation in Florence.
