“…Both techniques were used for the first time in the 50's. The HTHP uses an high temperature (1,000-1,400 • C) high pressure (45)(46)(47)(48)(49)(50)(51)(52)(53)(54)(55)(56)(57)(58)(59)(60) process, reproducing the condition of natural formation of diamond. The CVD technique, instead, uses a lower temperature (<1,000 • C) and low pressure (∼ 0.1 bar), producing the highest quality diamond to date.…”

“…A new architecture, named Double Diamond (DD), was later developed for the 2018 data taking in which some layers of SD diamonds were replaced. DD architecture has been developed to achieve better time performance [54] with a single detector plane. In this design, two diamond crystals with the same metallization geometry are glued on both sides of the hybrid board, with corresponding pads connected to the same pre-amplification channel, as shown schematically in Figure 10.…”

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.

“…A time resolution of 80 ps was measured in a test beam for a single plane [2]. After further R&D studies, a time resolution of 50 ps was measured for a double-sided diamond detector [3], an improvement of 1.6 over the single-sided sensor. In a RP station on each side, one plane instrumented with one double-sided and three planes of single-sided diamond detectors are currently used in the 2018 data-taking.…”

Exclusive dilepton production occurs with high cross section in gamma-mediated processes at the LHC. The pure QED process γγ → ℓ + ℓ − provides the conditions to study particle production with masses at the electroweak scale. By tagging the leading proton from the hard interaction, the Precision Proton Spectrometer (PPS) provides an increased sensitivity to selecting exclusive processes. PPS is a detector system to add tracking and timing information at approximately 210 m from the interaction point around the CMS detector. It is designed to operate at high luminosity with up to 50 interactions per 25 ns bunch crossing to perform measurements of e.g. the quartic gauge couplings and search for rare exclusive processes. Since 2016, PPS has been taking data in normal high-luminosity proton-proton LHC collisions. Exclusive dilepton production with proton tagging, the first results obtained with PPS, and the status of the ongoing program are discussed.

“…This allows to reconstruct the longitudinal coordinate of the protons at the IP by measuring the difference of the proton arrival times in the two detector arms. Two sensor technologies have been exploited by the TOTEM collaboration, ultra-pure single crystal synthetic diamonds [4,5] and UltraFast Silicon Diode (UFSD) [6]. Diamond sensors are currently used in the horizontal RPs, operating in standard optics LHC run, and are part of the CT-PPS detector.…”

The new proton timing stations of the Totem experiment are based on UltraFast Silicon Detectors installed in Roman Pots at 220 m from the interaction point 5 at LHC. The sensors have shown in beam test a timing resolution in the range 30–100 ps, depending on the pixel size. The readout is performed through a fast sampler chip: the SAMPIC. The best timing resolution can indeed be obtained only by recording the full waveform of the detector signal. The challenges to integrate the chip and the detector in the Totem-CMS DAQ and control systems will be discussed, together with the solutions adopted. The system has been successfully operated in LHC during some commissioning runs and during the special run in July 2018.
