The LHC machine is planning an upgrade program which will smoothly bring the instantaneous luminosity to about $5-7.5\times10^{34}$\,cm$^{-2}$s$^{-1}$, to reach an integrated luminosity of $3000-4000$\,fb$^{-1}$ by the end of 2039. This High Luminosity LHC scenario, HL-LHC, will require an upgrade program of the LHC detectors known as Phase-2 upgrade. The current CMS Tracker, already running...
The CMS Collaboration is preparing to build a replacement endcap calorimeters for the Phase II of the LHC. This new high-granularity calorimeter (HGCAL) is designed to operate in the harsh radiation environment at the HL-LHC, where the average number of interactions per bunch crossing is expected to exceed 140 simultaneous collisions and neutron fluences can achieve >1016 1 MeV...
LGAD sensors have proven to be an excellent solution for 4D-tracking in HEP experiments thanks to the presence of internal gain that provides good time resolution also at high fluences (up to ∼2⋅1015 neq/cm2). However, approaching 1016 neq/cm2, the internal gain is completely lost due to the acceptor removal effect, leading to a...
The MONOLITH H2020 ERC Advanced project aims at producing a monolithic silicon pixel ASIC with 50µm pixel pitch and picosecond-level time stamping. The two main ingredients of the project are fast and low-noise SiGe BiCMOS electronics and a novel sensor concept, the Picosecond Avalanche Detector (PicoAD). The PicoAD uses a patented multi-PN junction to engineer the electric field and produce a...
Resistive Plate Chambers are widely used in present High Energy Physics experiments, and are foreseen to constitute an important part of the muon systems which will equip the experiments at the future colliders, like CEPC or FCC. However, they are operated filled with gases which, because of their large Global Warming Potential, are progressively being phased out, also according to regulations...
The Mu2e experiment at Fermi National Accelerator Laboratory will search for charged-lepton flavour violating neutrino-less conversion of negative muons into electrons in the Coulomb field of an Al nucleus. The conversion electron has a mono-energetic
104.967 MeV signature slightly below the muon mass and will be identified by a complementary measurement carried out by a high-resolution...
In physics and other disciplines, future experimental setups will be so complex that it will be unfeasible for humans to find an optimal set of design parameters. We parameterize the full design of an experiment in a differentiable way and introduce a definition of optimality based on a loss function that encodes the end goals of the experiment. Crucially, we also account for construction...
Answering the most puzzling questions in fundamental physis posed by HEP drives a continuous quest for improvements in current particle detection techniques as well as for the development of new ones. Among the novel detection approaches under investigation, the development of innovative devices based on exploiting the extreme sensitivity of quantum systems is considered to have promising...
Cryogenic Bulk Acustic Wave (BAW) cavities can be used as narrow band and high resolution antennas for high frequency GWs (1 MHz - 1 GHz). Such GWs might be produced by several cosmological sources: from the merging of compact binary objects to the annihilation of QCD axions close to a black hole. Based on studies conducted at University of Western Australia, I'll describe how: a BAW can be...
SND@LHC is a compact and stand-alone experiment to perform measurements with neutrinos produced at the LHC in the pseudo-rapidity region of $7.2 < \eta < 8.6$, complementary to all the other experiments at the LHC.
The experiment will be located 480~m downstream of the ATLAS interaction point, in a previously unused LHC service tunnel. The detector is composed of a hybrid system based on an...
SND@LHC is a compact and stand-alone experiment that performed the first collider neutrino observation at the LHC.
The detector, located 480 m from the ATLAS interaction point, is composed of a target region, followed downstream by a hadronic calorimeter and a muon identification system.
The target region is instrumented with five walls of emulsion cloud chambers, each followed by a...
