“…First beam test results on thin UFSD manufactured by CNM have been obtained in 2016 [43]. The Fondazione Bruno Kessler (FBK) has also designed [30] and produced LGAD sensors, up to now only 300-micron thick; first FBK production of thin LGAD is expected in early 2017.…”

The evolution of particle detectors has always pushed the technological limit in order to provide enabling technologies to researchers in all fields of science. One archetypal example is the evolution of silicon detectors, from a system with a few channels 30 years ago, to the tens of millions of independent pixels currently used to track charged particles in all major particle physics experiments. Nowadays, silicon detectors are ubiquitous not only in research laboratories but in almost every high-tech apparatus, from portable phones to hospitals. In this contribution, we present a new direction in the evolution of silicon detectors for charge particle tracking, namely the inclusion of very accurate timing information. This enhancement of the present silicon detector paradigm is enabled by the inclusion of controlled low gain in the detector response, therefore increasing the detector output signal sufficiently to make timing measurement possible. After providing a short overview of the advantage of this new technology, we present the necessary conditions that need to be met for both sensor and readout electronics in order to achieve 4D tracking. In the last section, we present the experimental results, demonstrating the validity of our research path.

High energy particle collider experiments are facing ever more challenging conditions, operating at todays accelerators capable of providing instantaneous luminosities of 10 34 cm −2 s −1 and above. The high center of mass energy, the large number of simultaneous collision of beam particles in the experiments and the very high repetition rates of the collision events pose huge challenges. They result in extremely high particle fluxes, causing very high occupancies in the particle physics detectors operating at these machines. A precise timing information with a precision of around 10 ps and below is seen as a major aid in the reconstruction of the physics events under such challenging conditions. In this paper I discuss applications of precision timing in high pile-up conditions and review the efforts of the LHC collaborations to augment the timing performance of their detectors during future upgrade campaigns. Different detector technologies allowing precision timing measurements will be discussed and their potential benefit for a holistic event reconstruction will be illustrated.

“…A beam test of Ultra-Fast Silicon Detectors (UFSD) recently demonstrated a time resolution of about 30 ps on pad sensors with an area of 1.7 mm 2 [4]. This result is based on the use of 50 µm thick n-on-p Low-Gain Avalanche Detectors (LGAD) with p+ multiplication layer, coupled to a fast amplifier and a 20 GS/s digital oscilloscope.…”

We propose an innovative detector capable of performing high resolution tracking with ultraprecise time tagging to allow the High Luminosity LHC (HL-LHC) experiments to fully profit from the luminosity upgrade of the accelerator. The increase in the number of visible interactions per bunch crossing will lead to a much larger number of primary vertices and tracks compared to the current LHC conditions, and will inevitably increase tracking inefficiency and ghost track rate. We aim to develop a detector capable of providing 4-dimensional (4D) information, with time resolution in the order of 10 ps and position resolution of about 10 µm, able to operate in a harsh radiation environment exceeding 10 16 1-MeV neutrons equivalent per cm 2 and with fast online track triggering capabilities. The precise measurement of the hits time is the key feature to operate an effective pattern recognition that guarantees a high tracking efficiency while enhancing ghost track rejection, and to perform selective track triggering. This detector system will allow to perform precision physics measurements at the HL-LHC operating at instantaneous luminosities almost one order of magnitude larger than the current ones, making efficient use of the whole delivered luminosity.
