/ Centis Vignali, M (CERN) ; Dalal, R (Delhi U.) ; Gallinaro, M (CERN ; LIP, Lisbon) ; Harrop, B (Princeton U.) ; Jain, G (Delhi U.) ; Lu, C (Princeton U.) ; McClish, M (Radiat. Monitor. Devices, Watertown) ; McDonald, K T (Princeton U.) ; Moll, M (CERN) ; Newcomer, F M (Pennsylvania U.) et al.
For their operation at the CERN High Luminosity Large Hadron Collider (HL-LHC), the ATLAS and CMS experiments are planning to implement dedicated systems to measure the time of arrival of minimum ionizing particles with an accuracy of about 30 ps. The timing detectors will be subjected to radiation levels corresponding up to a 1-MeV neutrons fluence ($\Phi_{\mathrm{eq}}$) of $10^{15}$ cm$^{−2}$ for the goal integrated luminosity of HL-LHC of 3000 fb$^{−1}$.

Deep Diffused APDs for Charged Particle Timing Applications: Performance after Neutron Irradiation
/ Centis Vignali, M. (CERN) ; Gallinaro, M. (CERN ; LIP, Lisbon) ; Harrop, B. (Princeton U.) ; Lu, C. (Princeton U.) ; McClish, M. (Radiat. Monitor. Devices, Watertown) ; Moll, M. (CERN) ; Newcomer, F.M. (Pennsylvania U.) ; Otero Ugobono, S. (CERN ; Santiago de Compostela U.) ; White, S. (CERN ; Virginia U.)
Recent interest in pile-up mitigation through fast timing at the HL-LHC has focused attention on technologies that now achieve minimum ionising particle (MIP) time resolution of 30 picoseconds or less. The constraints of technical maturity and radiation tolerance narrowed the options in this rapidly developing field for the ATLAS and CMS upgrades to low gain avalanche detectors and silicon photomultipliers.

The upgrades of ATLAS and CMS for the High Luminosity LHC (HL-LHC) highlighted physics objects timing as a tool to resolve primary interactions within a bunch crossing. Since the expected pile-up is around 200, with an r.m.s. [...]

Position resolution with 25 $\mu$m pitch pixel sensors before and after irradiation
/ Ebrahimi, Aliakbar (PSI, Villigen) ; Feindt, Finn (Hamburg U.) ; Garutti, Erika (Hamburg U.) ; Gunnellini, Paolo (Hamburg U.) ; Hinzmann, Andreas Dominik (Hamburg U.) ; Niemeyer, Caroline (Hamburg U.) ; Pitzl, Daniel (DESY) ; Schwandt, Joern (Hamburg U.) ; Steinbrueck, Georg (Hamburg U.) ; Zoi, Irene (Hamburg U.)
Pixelated silicon detectors are state-of-the-art technology to achieve precise tracking and vertexing at collider experiments, designed to accurately measure the hit position of incoming particles in high rate and radiation environments.
The detector requirements become extremely demanding for operation at the High-Luminosity LHC, where up to 200 interactions will overlap in the same bunch crossing on top of the process of interest. [...]

Radiation hardness and timing performance in MALTA monolithic pixel sensors in TowerJazz 180 nm
/ van Rijnbach, M (CERN ; Oslo U.) ; Allport, P (Birmingham U.) ; Asensi, I (Valencia U.) ; Berdalovic, I (Zagreb U.) ; Bortoletto, D (Oxford U.) ; Buttar, C (Glasgow U.) ; Cardella, R (Geneva U.) ; Dachs, F (CERN) ; Dao, V (CERN) ; Denizli, H (Abant Izzet Baysal U.) et al.
The MALTA family of depleted monolithic pixel sensors produced in TowerJazz 180 nm CMOS technology target radiation hard applications for the HL-LHC and beyond. Several process modifications and front-end improvements have resulted in radiation hardness >10$^{15}$ 1 MeV n$_{eq}$/cm$^{2}$ and time resolution below 2 ns, with uniform charge collection and efficiency across the pixel of size 36.4 × 36.4 µm$^{2}$ with small collection electrode.
