Particle physics experiments running at future accelerator facilities will rely on fast timing detectors to cope with high event pileup and to enhance particle identification capabilities. Direct band gap engineered semiconductor nanostructures show a high potential for emission of prompt photons due to quantum confinement, standing out in fast timing and high light yield with potential low cost production, thus triggering interest in the high energy physics community.

Time resolution plays a key role in positron emission tomography (PET) by enhancing the signal-to-noise ratio and ultimately improving the quality of the image. In previous studies, an array of 16 LYSO crystals (measuring 3.1x3.1x15 mm$^3$) coupled to Hamamatsu S13361-3050AE-04 SiPMs and readout by a custom-made NINO board achieved a coincidence time resolution (CTR) below 160 ps.

TlCl: Be, I: towards a superior Scintillation and Cherenkov emitter for medical imaging
/ Kratochwil, N (UC, Davis ; CERN) ; Kaneshige, N (Radiat. Monitor. Devices, Watertown) ; Terragni, G (CERN ; TU Vienna) ; Cala, R (CERN ; Milan Bicocca U.) ; Hillemanns, E Auffray (CERN) ; Pandian, L S (Radiat. Monitor. Devices, Watertown) ; Glodo, J (Radiat. Monitor. Devices, Watertown) ; Roncali, E (UC, Davis) ; Ariño-Estrada, G (UC, Davis)
The material requirements for gamma-ray detectors for medical imaging applications are multi-fold and sensitivity is often overlooked. High effective atomic number (Zeff) Cherenkov radiators have raised the attention in the community due to their potential for harvesting prompt photons.A material with one of the highest Zeffand thus low gamma-ray attenuation length is thallium chloride (TlCl).

Heterostructured scintillators are gaining ground as a possible solution to the trade-off between the high sensitivity and fast timing of detectors for time-of-flight positron emission tomography (TOF-PET). They consist of stacks of alternating layers of two materials with complementary properties: high stopping power and ultrafast timing. [...]

The emerging field of ultra-fast timing has enormous potential in high-energy physics, nuclear medicine, and imaging, and is driving advances in detector and readout electronics. To achieve improved time resolution, significant efforts have been devoted to this field, resulting in impressive coincidence time resolution (CTR) values for silicon photomultiplier (SiPM) and scintillator crystals using state-of-the-art high-frequency (HF) readout.

The Spaghetti type Calorimeter (SPACAL) with fibers parallel to the beam direction is considered as an option for the inner part of the future LHCb Electromagnetic Calorimeter (ECAL) for the Upgrade Phase 2 [1]. In this work a simulation study of the time measurement precision has been performed for the electron and photon beams with energies of 1, 2, 4, 5 and 10 GeV..
