The performance of the LHCb Muon system and its stability across full 2010 data taking with LHC running at ps = 7 TeV energy is studied. optimization detector setting time calibration performed first collisions delivered by described. Particle rates, measured for wide range luminosities beam operation conditions experienced during run, are compared values expected from simulation. space alignment detectors, chamber efficiency, resolution cluster size evaluated. found to be as specifications...
The Crilin calorimeter is a semi-homogeneous calorimetric system that uses Lead Fluoride (PbF 2 ) crystals with UV-extended Silicon Photomultipliers (SiPMs). Proposed for the Muon Collider, it requires high granularity to distinguish signal particles and address substructures jet identification. Anticipating substantial occupancy due beam-induced backgrounds, simulations indicate photon flux an average energy of 1.7 MeV approximately 4.5 MHz/cm fluence rate. Prioritizing time-of-arrival...
Abstract The measurement of physics processes at new energy frontier experiments requires excellent spatial, time, and resolutions to resolve the structure collimated high-energy jets. In a future Muon Collider, beam-induced backgrounds (BIB) represent main challenge in design detectors event reconstruction algorithms. technology calorimeters should be chosen reduce effect BIB, while keeping good performance. Several requirements can inferred: i) high granularity overlap BIB particles same...
Abstract Lead fluoride (PbF 2 ) crystals represent an excellent and relatively innovative choice for high resolution electromagnetic calorimeters with granularity fast timing intensity environments. For this reason two PbF crystals, sized 5× 5 × 40 mm 3 , were irradiated 60 Co photons up to ∼ 4 Mrad 14 MeV neutrons a 10 13 n/cm total fluence. Their loss in transmittance was evaluated at different steps of the photon neutron irradiation campaign, resulting 30% above 350 nm. With always kept...
The Mu2e experiment at Fermilab searches the neutrino-less conversion of muon into electron in field an Aluminum nucleus. If such a process will be observed, it proof charged-lepton-flavor-violation (cLFV), otherwise set upper limit Rμe < 6 × 10−17 @ 90% C.L. (which represents improvement by 3–4 order magnitude over existing limit). detector apparatus consists magnetic spectrometer, devoted to measurement electrons momentum, and electromagnetic calorimeter (EMC) which provides independent...

Accurate measurements of physical processes in high energy frontier experiments demand exceptional spatial, temporal, and precision to discern the physics behind high-energy particle jets. Calorimeters, like other detection systems, must be able meet these increasingly challenging performance requirements. In prospective TeV-scale Muon Collider, primary hurdle designing detectors devising event reconstruction algorithms is challenge posed by Beam-Induced Background (BIB). Nevertheless, it...
The Mu2e experiment is constructing a calorimeter consisting of 1,348 undoped CsI crystals in two disks. Each crystal has dimension 34 x 200 mm, and readout by large area silicon PMT array.

The muon detector of LHCb, which comprises 1368 multi-wire-proportional-chambers (MWPC) for a total area 435 m2, is the largest instrument its kind exposed to such high-radiation environment. In nine years operation, from 2010 until 2018, we did not observe appreciable signs ageing in terms reduced performance. However, during long period, many chamber gas gaps suffered HV trips. Most trips were due Malter-like effects, characterised by appearance local self-sustained high currents,...

Since the first version of Mu2e TDR released at beginning 2015, Calorimeter system has undergone a long list changes to arrive its final design. These were primarily caused by two reasons: (i) technology choice between proposed solution BaF2 crystals readout with solar blind Avalanche Photodiodes (APDs) and backup option CsI Silicon Photomultipliers (SiPM) been completed (ii) channels numbering, mechanical electronics substantially modified while proceeding engineering towards project. This...
