Non-HEP applications

Silicon tracking detectors are playing a crucial role in space-borne astroparticle experiments for the measurement of both charged cosmic rays and gamma rays.
The technology used for accelerator based experiments has been proven to work properly in space with high reliability and is used in several running and planned experiments.
I will review the current experiments equipped with silicon...

19. A program for fast calculation of capacitances, in planar pixel and strip silicon sensors

Panagiotis Assiouras (National Center for Scientific Research Demokritos, Institute of Nuclear and Particle Physics, Agia Paraskevi, Greece)

Poster

We present a program for fast calculation of capacitances in planar silicon pixel (strip) sensors, based on a 3D (2D) numerical solution of the Laplace equation. A comparison between calculated capacitances and measurements on pixel and strip sensors, along with simulation results obtained with the TCAD Sentaurus suite are presented. The agreement between calculations and measurements better...

57. Ageing tests of the Hybrid Modules for the ALICE ITS Upgrade

Nicolo' Valle (University and INFN Pavia (IT))

Poster

The ALICE experiment foresees a comprehensive upgrade during the ongoing long LHC shutdown. A key element is the replacement of the Inner Tracking System (ITS) with a newly constructed silicon based detector. The new "ALPIDE" chips made from Monolithic Active Pixel Sensors (50 $\mu$m thick) have already shown excellent performances in terms of power consumption and spatial precision. Once...

60. Assembly and Commissioning of the ALICE ITS Upgrade

Tatiana Lazareva (St Petersburg State University (RU))

Poster

The major upgrade of the Inner Tracking System (ITS) of the ALICE detector is being carried out to meet the challenges of the physics program of the ALICE experiment after the LHC Long Shutdown 2.The strategy of the ALICE ITS upgrade is based on the application of Monolithic Active Pixel Sensors (MAPS) developed by the ALICE collaboration using 0.18$~$$\mu$m TowerJazz technology. These sensors...

6. Beam test measurements of radiation hard monolithic CMOS sensors for the ATLAS experiment at the HL-LHC

Maria Mironova (University of Oxford (GB))

Poster

Monolithic Active Pixel Sensor prototypes developed in the TowerJazz 180 nm CMOS imaging process have been designed in the context of the ATLAS upgrade Phase-II at the High-Luminosity LHC. These are characterized by a small collection electrode design (3 um), and a small pixel size (36.4 um), on high resistivity substrates and large voltage bias. The latest prototype of this technology,...

25. Cobalt-60 gamma irradiation of silicon test structures for high-luminosity collider experiments

Patrick Asenov (NCSR Demokritos, Institute of Nuclear and Particle Physics, Athens, Greece )

Poster

During the era of the High-Luminosity (HL) LHC the experimental devices will be subjected to enhanced radiation levels with fluxes of neutrons and charge hadrons in the inner detectors up to ~2.3x1016 neq/cm2 and total ionization doses up to ~1.2 Grad. A systematic program of radiation tests with neutrons and charge hadrons is being run by the CMS and ATLAS collaborations in view of the...

17. Design of a Segmented LGAD Sensor for Development of 4-D Tracking Detector

sayaka Wada (University of Tsukuba)

Poster

The tracking detector capable of recording the hit-time information in a precision of O(10ps) should become a breakthrough device in future hadron collider experiments to resolve signal tracks in the harsh environment with enormous background tracks. LGAD (low-gain avalanche detector) is one of such candidates, which is expected to provide fine spatial resolution at the same time; hence to...

15. High performance 4D tracking with 100% fill-factor and very fine pitch silicon detectors

Federico Siviero (Universita e INFN Torino (IT))

Poster

In our contribution we present the performance of RSD (Resistive AC-Coupled Silicon Detectors), an evolution of the LGAD (Low-Gain Avalanche Diode) technology, developed through a collaboration between the Torino division of INFN (the Italian National Institute for Nuclear Physics) and Fondazione Bruno Kessler (FBK), Trento. In this new design, the multiplied charges are slowed down on the...

68. Low dose rate 60Co facility in Zagreb

Matej Roguljic (Rudjer Boskovic Institute (HR))

Poster

The Co-60 irradiation facility at the Ruder Boskovic Institute in Zagreb will be presented. Preliminary results of the irradiation of an ATLAS and CMS pixel detector prototype readout chip, called RD53A, will be discussed.
Recent results have shown evidence of enhanced low dose-rate radiation sensitivity (ELDRS) to the total ionizing dose (TID) induced damage in 130- and 65-nm CMOS...

18. Prototype module construction for the high luminosity upgrade of the CMS pixel detector

Branislav Ristic (IPA - ETH Zürich)

Poster

With the planned upgrades of the LHC towards a high luminosity, the entire CMS silicon tracker will be replaced in order to cope with the resulting elevated pileup and radiation levels. To meet these requirements for the inner tracker, a new pixel readout chip was developed by the RD53 collaboration in 65nm CMOS technology, featuring a higher readout bandwidth and increased granularity and...

47. Radiation Hardness Studies of ALPIDE, the CMOS sensor for the ALICE ITS Upgrade

Ms Valentina Raskina (student)

Poster

The ALICE (A Large Ion Collider Experiment) experiment at CERN is undergoing a major upgrade of its Inner Tracking System (ITS) detector. The new ITS will have seven concentric cylindrical layers of monolithic active pixel sensors ALPIDEs, which are based on the 180 nm CMOS technology by TowerJazz. It is expected that during their operation, the sensors in the innermost layer will obtain a...

51. Series Production and Test of Hybrid Modules for the ALICE ITS Upgrade

Matthew Daniel Buckland (University of Liverpool (GB))

Poster

ALICE is one of the four experiments at the LHC located at CERN. As part of the upgrade of the detector, the current Inner Tracking System (ITS) will be replaced by an all silicon detector constructed from pixel sensors with a pitch of 29 × 27 µm$^2$ using CMOS Monolithic Active Pixel Sensors (MAPs) technology. The goal of this upgrade is to enable precise measurements of low momenta particles...

Edoardo Rossi (Deutsches Elektronen-Synchrotron (DE))

Poster

After more than ten years of operations, starting from 2024 the LHC will be upgraded to the High-Luminosity LHC (HL-LHC). The HL-LHC will deliver a total integrated luminosity of up to 4000fb-1 in about ten years, with a peak luminosity five times higher than that which was reached before the current LHC shutdown. To cope with the higher radiation levels and pile up, the ATLAS experiment will...

Karel Cerny (Palacky University (CZ))

Poster

The Time-of-Flight (ToF) detectors of the ATLAS Forward Proton (AFP) system are designed to measure the primary vertex z-position of the pp -> pXp processes by comparing the arrival times measured in the ToF of the two intact protons in the final state.
We present the results obtained from a performance study of the AFP ToF detector operation in 2017. A time resolutions of individual channels...
