Description
Detectors for High Radiation and Extreme Environments
A lot of R & D work is carried out in the CERN RD50 Collaboration to find out the best material for the Si detectors that can be used in the harsh radiation environment of HL-LHC, n and p-MCz Si was identified as one of the prime candidates as a material for n in p strip detector that can be chosen for the phase 2 upgrade plan of the new Compact Muon Solenoid tracker detector in 2026.
For...
The motivation of this study is the development of next generation capacitively coupled (AC-coupled) pixel sensors with coupling insulators having good dielectric strength and radiation hardness simultaneously. The AC-coupling insulator thin films were aluminum oxide (Al2O3) and hafnium oxide (HfO2) grown by Atomic Layer Deposition (ALD) method. The Al2O3 thin films were...
Radiation damage of the silicon strip detectors in the HL-LHC experiments pretenses a major task for its reliable long –term operation of the experiment. Radiation hard Si detectors have used in the new CMS tracker detector at HL-LHC in 2026. It has been observed that n-MCz and n-Fz Si as a material can be used for the Si microstrip detector. The strip detector design for this material should...
The Transient Current Technique (TCT) is widely used in the field of silicon particle
detector development. So far, mainly Single Photon Absorption – Transient Current
Technique (SPA-TCT) was performed, using laser wavelengths with a photon energy
larger than or similar to the silicon band-gap. Recently, measurements employing two
photon absorption for the testing of the silicon bulk...
Operation at the High Luminosity LHC (HL-LHC) requires the pixel detectors of ATLAS and CMS to separate collisions occurring with an extremely high pile-up. Fast detectors with a small pixel size are therefore needed such that thousands of charged particles per event can be reconstructed with high fidelity and excellent vertexing resolution.
The RD53 collaboration has been working on the...
Silicon detectors are expected to suffer unprecedented radiation damage in future high-luminosity collider detectors. Device modelling is required for detailed understanding of the performance of silicon detectors over the lifetime of the detector and to set design rules to mitigate the detrimental effect provided by radiation damage.
In the present work, results of a comprehensive...
Silicon detectors are currently filling the trackers of largest particle accelerators and colliders. Their radiation hardness, spatial resolution and availability in large volume foundries make silicon the best candidate for tracking detectors. Current experiments such as ATLAS in the LHC and future experiments foresee to populate the innermost tracking layers with silicon detectors. But not...
The search for Neutrinoless Double-Beta Decay (0νββ) at tonne-scale and beyond requires techniques that are capable of observing a sharp peak at Qββ in the total beta energy spectrum. A direct charge sensor, Topmetal-S, with only one charge collection electrode on a single sensor and with the intention to tile many such sensors on a large plane, is being developed for 0νββ experiments in a...
The LUXE experiment aims at studying high-field QED in electron-laser and photon-laser interactions, with the 16.5 GeV electron beam of the European XFEL and a laser beam with power of up to 350 TW. The experiment will measure the spectra of electrons and photons in non-linear Compton scattering where production rates in excess of 109 are expected per 1 Hz bunch crossing. At the same time...
The Mu2e experiment at Fermilab will search for the CLFV neutrino-less coherent conversion of a muon into an electron in the field of an aluminum nucleus. The observation of this process would be the evidence of physics beyond the Standard Model. Mu2e comprises a straw-tracker, an electromagnetic calorimeter and an external veto for cosmic rays. The calorimeter provides electron...
