“…Work is ongoing to demonstrate that ultra-fast timing can be used to resolve the development of hadron showers and therefore improve the resolution of hadron calorimeters. Results from beam tests have shown that the timing resolution obtained with Si-sensors does not vary significantly with a thickness as a function of S/N [164]. Figure 15 (right) shows that 30 ps time resolution for S/N > 20 can be achieved for charged particle detection.…”

The physics goals of high luminosity particle accelerators, from LHC to HL-LHC and to the next generation of lepton colliders, have set quite stringent constraints on the future needs at the Instrumentation Frontier. Many technologies are reaching their sensitivity limit and new approaches need to be developed to overcome the currently irreducible technological challenges. The detrimental effect of the material budget and power consumption represents a very serious concern for a high-precision silicon vertex and tracking detectors. One of the most promising areas is CMOS sensors offering low mass and potentially radiation-hard technology for the future proton-proton and electron-positron colliders, intensity frontier and heavy-ion experiments. MPGDs have become a well-established technique in the fertile field of gaseous detectors; these will remain the primary choice whenever the large-area coverage with low material budget is required. Vacuum tube technology is inherently fast and new developments include advances in microchannel plates for photomultipliers with a potential for a picosecondtime resolution in large systems. Several novel concepts of picosecond-timing detectors will have numerous powerful applications in particle identification, pile-up rejection and event reconstruction, and serve numerous scientific goals. The story of modern calorimetry is a textbook example of physics research driving the development of an experimental method. Silicon photomultipliers have seen a rapid progress in the last decade, becoming the standard solution for scintillator-based devices. The integration of advanced electronics and data transmission functionalities plays an increasingly important role and needs to be addressed. Bringing the modern algorithmic advances from the field of machine learning from offline applications to online operations and trigger systems is another major challenge. The timescales spanned by future projects in particle physics, ranging from few years to many decades, constitute a challenge in itself, in addition to the complexity and diversity of the required accelerator and detector R&D. This paper summarizes advances and recent trends in the instrumentation techniques for particle physics experiments, largely based on the presentations given at the International Conference "Instrumentation for Colliding Beam Physics" (INSTR-20), held at BINP Novosibirsk, Russia, from 24 to

“…The pulse from each diode was digitized at 5 GHz and the pulse amplitude and timing information were extracted on an event-by-event basis, following the same procedure as in [6]. To estimate the timing capabilities of these devices, the timing measured by each diode is compared to that of an unirradiated diode of the same thickness and type.…”

The High Granularity Calorimeter (HGCAL) is the technology choice of the CMS collaboration for the endcap calorimetry upgrade planned to cope with the harsh radiation and pileup environment at the High Luminosity-LHC. The HGCAL is realized as a sampling calorimeter, including an electromagnetic compartment comprising 28 layers of silicon pad detectors with pad areas of 0.5-1.0 square centimetres interspersed with absorbers. Prototype modules, based on hexagonal silicon pad sensors, with 128 channels, have been constructed and tested in beams at FNAL and at CERN. The modules include many of the features required for this challenging detector, including a PCB glued directly to the sensor, using through-hole wire-bonding for signal readout and 5mm spacing between layers-including the front-end electronics and all services. Tests in 2016 have used an existing front-end chip-Skiroc2 (designed for the CALICE experiment for ILC). We present results from first tests of these modules both in the laboratory and with beams of electrons, pions and protons, including noise performance, calibration with mips, electron energy resolution and precision-timing measurements.

“…In [6] the time resolution for multiple particles crossing a sensor is discussed. The case of n particles passing the silicon sensor is equivalent to the situation of one particle passing the sensor with a mean free path between collisions reduced to to λ n = λ/n.…”

“…A time resolution of 100 ps has been reported with a sensor of 100 µm thickness and 800 µm×800 µm pixel size [5]. For multiple particles passing silicon sensors of thickeness between 133 and 285 µm, a time resolution of better than 20 ps has been reported [6]. With the introduction of internal amplification inside silicon detectors of 50 µm thickness, the so called Low Gain Avalanche Diode (LGAD) [7][8] [9][10] [11], time resolutions of 25 ps have been achieved for single MIPs [12].…”

We derive expressions for the time resolution of silicon detectors, using the Landau theory and a PAI model for describing the charge deposit of high energy particles. First we use the centroid time of the induced signal and derive analytic expressions for the three components contributing to the time resolution, namely charge deposit fluctuations, noise and fluctuations of the signal shape due to weighting field variations. Then we derive expressions for the time resolution using leading edge discrimination of the signal for various electronics shaping times. Time resolution of silicon detectors with internal gain is discussed as well.
