“…The Timing Optimized PID Silicon Detector (TOPSiDE) concept [5][6][7] for the Electron-Ion Collider (EIC) at the Brookhaven National Laboratory is one such application that implements a 4D concept requiring precision timing on the order of 10 ps. With such precision, pion/kaon separation up to 7 GeV/c is expected using the ToF method with the efficiency of 90% [8]. It provides the precision measurements required for the EIC's broad physics program; some major topics include deep inelastic structure functions of protons and nuclei, spin structure functions, generalized parton distributions, and transverse momentum dependent distributions [9].…”

This paper presents results that take a critical step toward proving 10 ps timing resolution's feasibility for particle identification in the TOPSiDE detector concept for the Electron-Ion Collider. Measurements of LGADs with a thickness of 35 μm and 50 μm are evaluated with a 120 GeV proton beam. The performance of the gain and timing response is assessed, including the dependence on the reverse bias voltage and operating temperature. The best timing resolution of UFSDs in a test beam to date is achieved using three combined planes of 35 μm thick LGADs at -30°C with a precision of 14.3 ± 1.5 ps.

“…A timing resolution of 12 psec could be achievable for a heavily biased (200 V) 50 µm thick sensor with a very low noise readout [9]; sub 10-psec resolution could be achievable with slightly thinner sensors. The 10 psec level matches a planned silicon time-of-flight system for an EIC detector [10], so we will adopt it here. This paper will consider two cases: a possible all-silicon detector for an electron-ion collider, and for the CMS detector at the LHC.…”

A: Silicon tracking detectors provide excellent spatial resolution, and so can provide excellent momentum resolution for energetic charged particles, even in compact detectors. However, at lower momenta, multiple scattering in the silicon degrades the momentum resolution. We present an alternate method to measure momentum and alleviate this degradation, using silicon detectors that also incorporate timing measurements. By using timing information between two silicon layers, it is possible to solve for the the radius of curvature, and hence the particle momentum, independent of multiple scattering within the silicon. We consider three examples: an all-silicon central tracker for an electron-ion collider, a simplified version of the CMS detector, and a forward detector for an electron-ion collider. For a 75 cm diameter tracker in a 1.5 T magnetic field, timing can improve the momentum determination for particles with momentum below 500 MeV/c. In the 3.8 T CMS magnetic field and 1.2 m radius tracker, timing can improve tracking up to momenta of 1.3 GeV/c. The resolution is best at mid-rapidity. We also discuss a simpler system, consisting of a single timing detector outside an all-silicon tracker.
