The ATLASpix_Simple is a Monolithic Active Pixel Sensor prototype produced in a commercial 180nm HV-CMOS process. It contains a self-triggered 25 x 400 pixel array with a pixel size of 130 um x 40 um.
The chip features tunable in-pixel comparators and a digital periphery allowing for on-chip hit digitization.
In order to characterize the chip and investigate its performance with respect to...
The Mainz Microtron (MAMI) is an electron accelerator at the Institute for Nuclear Physics in Mainz, that provides beam energies of up to 1.6 GeV. With its narrow beam profile, quasi continuous stream of particles and beam currents of up to 100 $\mu$A it is well suited for diverse test beam applications. One of them is the high rate testing of detector prototypes.
The talk discusses tests that...
The ATLAS detector at CERN will undergo several updates for the High Luminosity phase of LHC in 2023. A completely new silicon tracker (ITk) will be installed.
Pixel modules built with the RD53A chip and planar sensors were studied using the EUDET telescope for reference tracks. Sensor thicknesses of 100 and 150 microns were investigated. Pixel sizes of 50 microns x 50 microns and 25 microns...
During the High-Luminosity phase of the LHC conditions for the ATLAS tracking system will be severe in terms of radiation and occupancy, with the goal of accumulating a total of more than 4000 fb$^{-1}$ of data and up to 200 inelastic proton-proton interactions per beam crossing. In order to deal with these conditions, the entire tracking system will be replaced by a new all-silicon detector...
Planar n+-in-n silicon pixel sensors used in tracking detectors like the ATLAS Inner Detector need a high efficiency to detect most of the traversing particles. Based on the IBL pixel design with a pitch of 250 µm x 50 µm new designs with modified n+-implants or bias grid modifications were developed in Dortmund to investigate the effects on the efficiency.
Several different modified designs...
The high luminosity upgrade of the LHC will lead to an increased multiplicity of proton-proton interactions, with up to 200 events per beam bunch crossing, in the CMS experiment.
The irradiation level that the detectors will have to withstand will reach a 1MeV neutron equivalent fluence of 2 $\times$ 10$^{16}$ n$_{eq}$/cm$^2$ at the innermost part of the CMS pixel detector, at 2.8 cm distance...
Radiation therapy is an important tool in the treatment of cancer tumors. During this treatment, the tumor is destroyed by irradiating it with photons or hadrons (protons or heavier nuclei). In hadron therapy, the organs surrounding the tumor receive a smaller dose than in the treatment done with photons; however, to plan such a treatment the energy loss of hadrons in the surrounding tissue...
