Radiation campaign of HPK prototype LGAD sensors for the High-Granularity Timing Detector (HGTD)
Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2020 We report on the results of a radiation campaign with neutrons and protons of Low Gain Avalanche Detectors (LGAD) produced by Hamamatsu (HPK) as prototypes for the High-Granularity Timing Detector (HGTD) in ATLAS. Sensors with an active thickness of 50~$μ$m were irradiated in steps of roughly 2$\times$ up to a fluence of $3\times10^{15}~\mathrm{n_{eq ...

A High-Granularity Timing Detector (HGTD) for the Phase-II upgrade of the ATLAS detector [PDF]
Journal of Instrumentation, 2019 The expected increase of the particle flux at the high-luminosity phase of the LHC (HL-LHC) with instantaneous luminosities up to L = 7.5× 1034 cm−1s−1 will have a severe impact on the ATLAS detector performance. The pile-up is expected to increase on average to 200 interactions per bunch crossing.

Interaction of pro-apoptotic protein HGTD-P with heat shock protein 90 is required for induction of mitochondrial apoptotic cascades [PDF]
FEBS Letters, 2006 HGTD‐P is a hypoxia‐responsive pro‐apoptotic protein that transmits hypoxic signals directly to mitochondria. When overexpressed, HGTD‐P induces cell death via typical mitochondrial apoptotic cascades. However, much is unknown about post‐transcriptional modification and signaling networks of HGTD‐P in association with cell death‐regulating proteins. We

ALTIROC1, a 25 pico-second time resolution ASIC for the ATLAS High Granularity Timing Detector (HGTD) [PDF]
Proceedings of Topical Workshop on Electronics for Particle Physics — PoS(TWEPP2019), 2020 ALTIROC1 is a 25-channel ASIC designed to read out the 5 x 5 matrix of 1.3 mm x 1.3 mm x 50 μm low Gain Avalanche Diodes (LGAD) of the ATLAS HGTD detector foreseen for the HL-LHC upgrade. The targeted combined time resolution of the sensor and the readout electronics is from 40 ps/hit (initial) to about 80 ps/hit (end of operational lifetime).

“ALTIROC0, a 20 pico-second time resolution ASIC for the ATLAS High Granularity Timing Detector (HGTD)” [PDF]
Proceedings of Topical Workshop on Electronics for Particle Physics — PoS(TWEPP-17), 2018 ALTIROC0 is an 8-channel ASIC prototype designed to readout 1x1 or 2x2 mm2 50 µm thick Low Gain Avalanche Diodes (LGAD) of the ATLAS High Granularity Timing Detector (HGTD). The targeted combined time resolution of the sensor and the readout electronics is 30 ps for one MIP. Each analog channel of the ASIC must exhibit an extremely low jitter to ensure

TCT-based monitoring of LGAD radiation hardness for ATLAS-HGTD production
Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated EquipmentProduction of the High Granularity Timing Detector for the ATLAS experiment at High Luminosity LHC requires over 21000 silicon sensors based on Low Gain Avalanche Diode (LGAD) technology. Their radiation hardness is monitored as a part of the production quality control.

Identification of the hypoxia-inducible factor 1 alpha-responsive HGTD-P gene as a mediator in the mitochondrial apoptotic pathway. [PDF]
Mol Cell Biol, 2004 Hypoxia-inducible factor 1 alpha (HIF-1 alpha) controls the cellular responses to hypoxia, activating transcription of a range of genes involved in adaptive processes such as increasing glycolysis and promoting angiogenesis. However, paradoxically, HIF-1 alpha also participates in hypoxic cell death.

A High-Granularity Timing Detector for the ATLAS Phase-II upgrade [PDF]
EPJ Web of Conferences, 2023 The High Luminosity Large Hadron Collider (HL-LHC) will reach an integrated luminosity up to 4 000 fb-1 from 2029 to 2039. The number of collisions per bunch crossing will significantly increase, rising a challenge in terms of pileup mitigation that will
