A review of advances in pixel detectors for experiments with high rate and radiation

, 2018
The Large Hadron Collider (LHC) experiments ATLAS and CMS have established hybrid pixel detectors as the instrument of choice for particle tracking and vertexing in high rate and radiation environments, as they operate close to the LHC interaction points.

Detection and correction of inclination shallowing in deep sea sediments using the anisotropy of anhysteretic remanence [PDF]

, 1993
Paleomagnetic data from recent Pleistocene to recent deep sea sediments from the continental rise of eastern North America exhibit a cyclical inclination shallowing, up to 30° with respect to the geocentric axial dipole value. This shallowing is strongly

Gauge Theory, Ramification, And The Geometric Langlands Program [PDF]

, 2006
In the gauge theory approach to the geometric Langlands program, ramification can be described in terms of ``surface operators,'' which are supported on two-dimensional surfaces somewhat as Wilson or 't Hooft operators are supported on curves.

AC-LGADs Fermilab front-end electronics characterization

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment
We characterized the front-end electronics used to process high-frequency signals from low-gain avalanche diodes (LGADs) at the Fermilab Test Beam Facility. LGADs are silicon detectors employed for charged particle tracking, offering exceptional spatial and temporal resolution.

Monitoring therapeutic proton beams with LGAD silicon detectors

Journal of Instrumentation, 2022
Abstract The University and the National Institute for Nuclear Physics of Torino are developing LGAD-based prototypes for beam monitoring in proton therapy. The direct measurement of single beam particles could overcome some features of currently used ionization chambers, such as slow charge collection and reduced sensitivity, which ...

Upgrade of the ATLAS Liquid Argon Calorimeters for the High-Luminosity LHC

, 2016
The increased particle flux at the high luminosity phase of the Large Hadron Collider (HL-LHC), with instantaneous luminosities of up to 7.5 times the original design value, will have an impact on many sub-systems of the ATLAS detector. This contribution

Silicon Sensor technologies for timing (LGAD) [PDF]

Proceedings of The 26th International Workshop on Vertex Detectors — PoS(Vertex 2017), 2018
The working conditions at future accelerators will require the capability of taking data at unprecedented intensities and the possibility to distinguish events separated by a few tens of picoseconds will become of utmost importance. To face this challenge, intense R&D programs in silicon sensors are currently being carried on, with the ultimate goal of

Development of low-energy X-ray detectors using LGAD sensors [PDF]

Journal of Synchrotron Radiation, 2019
Recent advances in segmented low-gain avalanche detectors (LGADs) make them promising for the position-sensitive detection of low-energy X-ray photons thanks to their internal gain. LGAD microstrip sensors fabricated by Fondazione Bruno Kessler have been investigated using X-rays with both charge-integrating and single-photon-counting readout chips ...
