Impact of the Guard Rings on Self-Induced Signal and Leakage Current in Trench-Isolated Low Gain Avalanche Diodes [PDF]
SensorsIn this contribution, we explored the interplay of guard ring (GR) configuration and isolation structures, as well as irradiation effects, which all together create a rich landscape of phenomena such as self-induced signals (“ghosts”) in trench-isolated ...

A High-Granularity Timing Detector for the Phase-II upgrade of the ATLAS Calorimeter system: detector concept, description and R&D and beam test results [PDF]
EPJ Web of Conferences, 2021 The particle flux increase (pile-up) at the HL-LHC with luminosities of L = 7.5 × 1034 cm−2 s−1 will have a significant impact on the reconstruction of the ATLAS detector and on the performance of the trigger. The forward region and the end-cap where the

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

Fabrication of Silicon Sensors Based on Low-Gain Avalanche Diodes
Frontiers in Physics, 2021 Low-Gain Avalanche Diodes are a recently-developed class of silicon sensors. Characterized by an internal moderate gain that enhances the signal amplitude and if built on thin silicon substrates of a few tens of microns, they feature fast signals and ...

Medical Physics, Volume 50, Issue 9, Page 5817-5827, September 2023., 2023 Abstract Background The beam energy is one of the most significant parameters in particle therapy since it is directly correlated to the particles’ penetration depth inside the patient. Nowadays, the range accuracy is guaranteed by offline routine quality control checks mainly performed with water phantoms, 2D detectors with PMMA wedges, or multi‐layer

The ASi–Sii Defect Model of Light‐Induced Degradation (LID) in Silicon: A Discussion and Review
physica status solidi (a), Volume 219, Issue 19, October 2022., 2022 ASi–Sii defect model of light‐induced degradation (LID) in silicon for solar cells and detectors is discussed and reviewed. LID cycle is explained within the ASi–Sii defect model by basic experiments (carrier lifetime and photoluminescence line). Implications related to the dependence of the LID defect density on the interstitial oxygen concentration ...

Development of Low‐Gain Avalanche Detectors in the Frame of the Acceptor Removal Phenomenon
physica status solidi (a), Volume 219, Issue 17, September 2022., 2022 Low gain avalanche detectors (LGAD) suffer from acceptor removal after irradiation. This is investigated in boron, gallium and indium implanted silicon by three methods. Secondary ion mass spectrometry (SIMS) boron depth profiles measured before and after irradiation show no fast movement of boron at room temperature.

Macrosomia and large for gestational age in Asia: One size does not fit all
Journal of Obstetrics and Gynaecology Research, Volume 47, Issue 6, Page 1929-1945, June 2021., 2021 Abstract Macrosomia, usually defined as infant birth weight of ≥4000 g, does not consider gestational age, sex, or country/region‐specific differences in mean birth weight and maternal body weight. This issue is particularly relevant for Asia, where 60% of the world's population lives, due to variations in maternal size and birth weights across ...
