Layout and Performance of HPK Prototype LGAD Sensors for the High-Granularity Timing Detector
X. Yang, S. Alderweireldt, N. Atanov +76
The High-Granularity Timing Detector is a detector proposed for the ATLAS Phase II upgrade. The detector, based on the Low-Gain Avalanche Detector (LGAD) technology will cover the…
Beam test measurements of Low Gain Avalanche Detector single pads and arrays for the ATLAS High Granularity Timing Detector
C. Allaire, J. Benitez, M. Bomben +41
For the high luminosity upgrade of the LHC at CERN, ATLAS is considering the addition of a High Granularity Timing Detector (HGTD) in front of the end cap and forward calorimeters…
Mapping the in-plane electric field inside irradiated diodes
L. Poley, A. J. Blue, C. Buttar +12
A significant aspect of the Phase-II Upgrade of the ATLAS detector is the replacement of the current Inner Detector with the ATLAS Inner Tracker (ITk). The ATLAS ITk is an all-sili…
Potential for Improved Time Resolution Using Very Thin Ultra-Fast Silicon Detectors (UFSDs)
A. Seiden, H. Ren, Y. Jin +14
Ultra-Fast Silicon Detectors (UFSDs) are n-in-p silicon detectors that implement moderate gain (typically 5 to 25) using a thin highly doped p++ layer between the high resistivity…
Effect of deep gain layer and Carbon infusion on LGAD radiation hardness
R Padilla, C. Labitan, Z. Galloway +22
The properties of 50 um thick Low Gain Avalanche Diode (LGAD) detectors manufactured by Hamamatsu photonics (HPK) and Fondazione Bruno Kessler (FBK) were tested before and after ir…
Experimental Study of Acceptor Removal in UFSD
Y. Jin, H. Ren, S. Christie +25
The performance of the Ultra-Fast Silicon Detectors (UFSD) after irradiation with neutrons and protons is compromised by the removal of acceptors in the thin layer below the juncti…
Radiation Campaign of HPK Prototype LGAD sensors for the High-Granularity Timing Detector (HGTD)
X. Shi, M. K. Ayoub, J. Barreiro Guimarães da Costa +74
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…
