Expression of interest for a postdoc grant at INFN Catania, with possibilities to work on Jiangmen Underground Neutrino Observatory (JUNO) experiment, Super Ballons II (SPB2) experiment, and Electron Ion Collider (EIC)
Introduction
JUNO experiment is a collaboration made of 74 institutes spreadover the worldworking on neutrino physics (Jiangmen Underground Neutrino Observatory (cas.cn) ).
The experiment is quite impressive, and it is going to produce between 2 and 3 PB of data per year, to be sharedbetween 4 data centres, to be storedand analysed. The lifespan of this experiment is of the order of 30 years.
The range of physics covered in JUNO comprehend neutrino mass ordering, solar neutrino, atmospheric neutrino, geo neutrino, super nova neutrinoand more. On the side of physicsanalysis, in Catania we are working on super nova neutrino.
JUNO activity in Catania is mainly focusedon super nova neutrino analysisin preparation of data taking.
The JEM-EUSO Program (https://www.jemeuso.org/), including SPB2 (Super Pressure Balloon II) mission and the future POEMMA (Probe of Extreme Multi-Messenger Astrophysics) Observatory, is designed to accurately observe ultra-high-energy cosmic rays (UHECRs) and cosmic neutrinos from space with sensitivity over the full celestial sky by observing the Extensive Air Showers (EASs) from UHECRs and UHE neutrinos above 20 EeV via air fluorescence. By a technological point of view, applicationsof silicon photomultipliers (SiPMs) in such aforementioned space-based experiments for High-Energy Multi-Messanger Astronomy is a new challenge never taken before. SiPMs are semiconductor photo-sensors employed in several scientific, medical and industrial applications, especially when fast time responseand weak light sensitivity in the I.R.-U.V. range are required. They are characterized by improved spectralsensitivity, robust mechanical properties and higherresilience in harsh environments. The SiPM technology is especially suitable in instrumenting imaging cameras of ground-based telescopes and for space-borne detectors in astrophysical experiments. In the framework of the JEM-EUSO Program, the main goal of this Post-Doc proposal is a full and extensive characterization of different SiPMs for applications in future detectors of space-based projects supported by ASI and NASA space agencies.
The ElectronIon Collider (EIC) project at Brookhaven NationalLaboratories (BNL) by the US Department of Energy (DoE) has triggered intense R&D programs, towards the choice of detectors.
A new experimental Collaboration is born (ePIC) on July 2022.
The experimental activity in which the Catania group is involved is to build and to test an dRICH (dual-radiator Ring Imaging Cherenkov) detector. The photosensors currently considered as baseline option are Silicon PhotoMultipliers (SiPM). INFN is currently leading a structured R&D program, supported also by DoE, to investigate the radiation effects on these devices, while maintaining the possibility to act as single photon detectors. The radiation environment will be moderately hostile, with a radiationload that shouldreach at maximuma fluence of 1011 1-MeV neq cm−2. An irradiation campaign on SiPM has been carried out at the TIFPA (Trento Institute for Fundamental Physics and Applications) and at the Laboratorio Nazionale di Legnaro (LNL) and others will take place in the coming months.
EIC activityin Catania is mainly focusedon SiPM
