4D diamond detectors: adding time resolution

We added time resolution to our laser fabricated 3D diamond detectors. See the paper in Nuclear Inst. and Methods in Physics Research, A for more info.

Tracking detectors for the future hadronic machines (HL-LHC and beyond) are expected to stand extreme levels of radiation and provide high space and time resolutions. Diamond detectors satisfy all these requirements. We report on the timing characterization of a 3D pixel diamond detector fabricated by laser graphitization with a 55 × 55 μm2 pixel geometry. Results of a tests beam provide a time resolution well below 100 ps with an efficiency larger than 99%.
