12. Investigation of Radiation Damage on Si e SiC Detectors

Carmen Altana (Istituto Nazionale di Fisica Nucleare)

2/20/24, 2:15 PM

The frontier activities of nuclear and subnuclear physics require devices with excellent performance in terms of stability and ability to operate at high fluxes of incident particles. Silicon carbide could be a good alternative to silicon devices due to its high resistance to radiation.
In this work we present the radiation damage study of a new, large area, p-n junction silicon carbide...

34. Defect Spectroscopy on Proton Irradiated 4H Silicon Carbide Devices

Moritz Wiehe (CERN)

2/20/24, 2:35 PM

Silicon Carbide (SiC) has gained attention in recent years for a number of benefits as a sensor material, especially its low leakage current in harsh radiation fields and at elevated temperatures. This study focuses on investigating intrinsic and radiation-induced defects in n-type 4H-SiC devices. The sensors studied were manufactured by IMB-CNM, with a 5µm or 50µm thick epitaxial layer on top...

4. A lightweight algorithm to model Radiation Damage Effects in Monte Carlo Events for High-Luminosity LHC experiments

Keerthi Nakkalil (University of Paris Cité)

2/20/24, 2:55 PM

Radiation damage significantly impacts the performance of silicon tracking detectors in Large Hadron Collider (LHC) experiments such as ATLAS and CMS, with signal reduction being the most critical effect. While adjusting sensor bias voltage and detection thresholds can help mitigate these effects, generating simulated data that accurately mirrors the performance evolution with the accumulation...

7. Compensated LGADs as a pathway to the extreme fluences

Valentina Sola (Istituto Nazionale di Fisica Nucleare)

2/20/24, 3:15 PM

The next generation of high-energy and high-intensity hadron colliders for particle physics will require tracking detectors able to efficiently record charged particles in harsh radiation environments, where expected fluences exceed 10$^{17}$ particles/cm$^{2}$.

Recently, thin Low-Gain Avalanche Diodes (LGADs), with an active thickness of $\sim$ 50 $\mu m$, have proven their ability to...

13. Studies of radiation damage and mitigation strategies for the SiPM of the ePIC-dRICH detector at the EIC

Nicola Rubini (Istituto Nazionale di Fisica Nucleare)

2/20/24, 3:35 PM

The dual-radiator (dRICH) detector of the ePIC experiment at the future Electron-Ion Collider (EIC) will make use of a large array of silicon photomultipliers (SiPM) sensors for the detection of the emitted Cherenkov light. The photodetector surface will cover ~ 3 m2 with 3x3 mm2 pixels, for a total of more than 300 k readout channels. SiPM is the emerging solid-state technology for photon...
