“…No dependence of the signal response of polycrystalline CVD (pCVD) diamond pad detectors, which were irradiated up to a neutron fluence of 5 × 10 14 n/cm 2 , on the particle flux up to 10 MHz/cm 2 was observed [11]. This study was extended and pCVD diamond samples were irradiated up to a larger neutron fluence [12]. Preliminary results of this study up to a neutron fluence of 4 × 10 15 n/cm 2 are presented in this article.…”

Timing detectors are a well-established part of High Energy Physics experimental instrumentation. The choice of sensors with fast (less than 10 ns) and precise (better than 100 ps) signals, together with radiation resistance considerations, are an essential part of the design of a timing detector. In this paper, the main characteristics that make single diamond crystal sensors ideal for timing applications will be described and an introduction to the design of fast front-end electronics will be given. Finally, two examples of diamond timing detectors used in High Energy Physics, the START detector of HADES and the TOTEM/CMS timing detector, will be discussed.

“…Differently from the silicon devices, where the electrodes are obtained with micromachining and doping, in diamond sensors the electrodes are usually obtained focusing a femtosecond laser within the diamond bulk to induce a local phase transition to an ohmic mixture of diamond-like carbon, amorphous carbon and graphite [18,19]. Recently, the single-hit efficiency of 3D sensors constructed with poly-crystalline chemical vapour deposition (CVD) diamond has been measured in a beam test using a high precision tracking telescope and found to be above 99% for particle fluxes up to 20 MHz/cm 2 and fluences up to 8 • 10 15 1 MeV n eq cm −2 [20].…”

Fabrication and Characterisation of 3D Diamond Pixel Detectors With Timing Capabilities

Diamond sensors provide a promising radiation hard solution to the challenges posed by the future experiments at hadron machines. A 3D geometry with thin columnar resistive electrodes orthogonal to the diamond surface, obtained by laser nanofabrication, is expected to provide significantly better time resolution with respect to the extensively studied planar diamond sensors. We report on the development, production, and characterisation of innovative 3D diamond sensors achieving 30% improvement in both space and time resolution with respect to sensors from the previous generation. This is the first complete characterisation of the time resolution of 3D diamond sensors and combines results from tests with laser, β rays and high energy particle beams. Plans and strategies for further improvement in the fabrication technology and readout systems are also discussed.
