“…The straightforward solution is to reduce the TW by improving the analog interface and specifically increasing the speed of the amplifier [9]. This equalizes the slope of the amplified signal for different energies but requires higher power and area consumption in the pixel, which has a negative impact on the granularity of the system (1 mm 2 pixel area).…”

Depleted Monolithic Active Pixel Sensors (DMAPSs) are foreseen as an interesting choice for future high-energy physics experiments, mainly because of the reduced fabrication costs. However, they generally offer limited time resolution due to the stringent requirements of area and power consumption imposed by the targeted spatial resolution. This work describes a methodology to optimize the design of time-to-digital converter (TDC)-based timing electronics that takes advantage of the asymmetrical shape of the pulse at the output of the analog front-end (AFE). Following that methodology, a power and area efficient implementation fully compatible with the RD50-MPW3 solution is proposed. Simulation results show that the proposed solution offers a time resolution of 2.08 ns for a range of energies from 1000 e− to 20,000 e−, with minimum area and zero quiescent in-pixel power consumption.

The Belle II barrel region is instrumented with the Time of Propagation (TOP) particle identification system based on sixteen fused-silica bars arranged around the interaction point acting as Cherenkov radiator. Due to the mechanical design of the TOP system these quartz bars do not overlap, but leave a gap of around 2 cm between them. This leads to around 6 % of all tracks in the nominal TOP acceptance region to escape without traversing any of the quartz bars and thus not giving any usable particle identification information from the TOP system and an additional 3 % of tracks being degraded due to edge effects. We propose a possible solution to remedy these gaps in the TOP acceptance in the form of a Supplemental TOP GAP instrumentation (STOPGAP) that covers the dead area between adjacent quartz bars with fast silicon detectors to directly measure the time-offlight of traversing particles for particle identification purposes. Modern, fast timing silicon sensors and readouts can offer sufficient time resolution for the task at hand, so that STOPGAP modules could be built compact enough to fit into the limited space available in the area of interest between the Belle II central drift chamber (CDC) and the TOP system.In this article, we present a simulation study demonstrating the feasibility of a silicon time-offlight system based on its reconstruction performance in Υ(4S) → B B events simulated using the Belle II simulation and reconstruction software. We discuss the performance requirements for possible sensor technologies and demonstrate that such a project could be realised with novel, fast monolithic CMOS sensors that are expected to reach MIP timing resolutions of down to 50 ps. Additionally, we discuss the use of fast timing layers at lower radii for track triggering as well as particle identification at low momenta <1 GeV/c.

“…They are also expected to significantly reduce costs while maintaining radiation hardness. An example of this sensor, Depleted Monolithic Active Pixel Sensor (DMAPS), is discussed in [35] • Micro-channel plate (MCP) detectors enable the detection of single ionizing particles to a precision of a few ps [36,37]. For example, Micro-Channel-Plate Photomultiplier Tubes (MCP-PMT), R3809U-50, by Hamamatsu, indicate a time resolution better than 10 ps [37].…”

In this White Paper for the 2021 Snowmass process, we discuss aspects of precision timing within electromagnetic and hadronic calorimeter systems for highenergy physics collider experiments. Areas of applications include particle identification, event and object reconstruction, and pileup mitigation. Two different system options are considered, namely cell-level timing capabilities covering the full detector volume, and dedicated timing layers integrated in calorimeter systems. A selection of technologies for the different approaches is also discussed.
