Description
Poster session of group A
The LHCb experiment is devoted to high-precision measurements of CP violation and search for New Physics by studying the decays of beauty and charmed hadrons produced at the Large Hadron Collider (LHC).
Two RICH detectors are currently installed and operating successfully, providing a crucial role in the particle identification system of the LHCb experiment.
Starting from 2019, the LHCb...
The Compressed Baryonic Matter (CBM) experiment at the future Facility for Antiproton and Ion Research (FAIR) complex will investigate the phase diagram of strongly interacting matter at high baryon density and moderate temperatures in nucleus-nucleus collisions. The beam energy will range from 2 up to 11 AGeV for the heaviest nuclei at the SIS 100 accelerator setup.
One of the key detector...
An Electron-Ion Collider (EIC) has been proposed to further explore
the strong force and QCD, focusing on the structure and the interaction of
the gluon-dominated matter.
A generic detector R&D program (EIC PID consortium) for the particle
identification in EIC experiments was formed to explore technologically
advanced solutions for that scope.
In this context two Ring Imaging Cherenkov...
The Aerogel Ring Imaging Cherenkov (ARICH) counter takes the role in particle identification at the endcap region of the Belle II detector. ARICH discriminates charged pions from kaons using the difference in radiation angle of Cherenkov light. ARICH is composed of aerogel tiles and Hybrid Avalanche Photo-Detectors (HAPDs). To keep high photon detection efficiency of HAPDs, periodical check of...
The CBM experiment at the future FAIR facility will investigate strongly interacting matter at high net-baryon densities but moderate temperatures in heavy-ion collisions with beam energies up to 11 AGeV (SIS 100). Electromagnetic radiation from the fireball is among the most sensitive probes for the created matter. In order to identify di-electrons in a momentum range up to 8 GeV/c, a RICH...
The Compressed Baryonic Matter (CBM) experiment at the future FAIR facility will investigate the QCD phase diagram at high net baryon densities and moderate temperatures in A+A collisions from 2-11 AGeV (SIS100). Electron identification in CBM will be performed by a Ring Imaging Cherenkov (RICH) detector and Transition Radiation Detectors (TRD).
A real size prototype of the RICH detector was...
We report on measurements of 511 keV annihilation photons with ultimate timing resolution via detection of Cherenkov radiation in
PbF2 crystals attached to an ultra-fast single-channel Micro-Channel PhotoMultiplier Tube (MCP-PMT). We have measured back-to-back timing resolution using a pair of such detectors, and compare the results with a Monte Carlo simulation. The study would provide useful...
The performance of the photon detectors in the upgraded LHCb RICH counters will be critical to the charged particle identification efficiency and to the physics goals of the LHCb experiment. Quantum Efficiency (QE) and the closely related the Photon Detection Efficiency (PDE) are the most important properties for single photon counting detectors. In vacuum photon tubes, the PDE generally is...
We present the performance of a novel neutron detection technique based on a
Water Cherenkov Detector (WCD) employing pure water, an inner coating material
acting as a light reflector and diffuser, and a single photomultiplier tube
(PMT). The detector employed in this work is part of the Latin American Giant
Observatory (LAGO) collaboration, that measures the low energy component of
cosmic...
The High Energy Stereoscopic System (H.E.S.S.) is an array of imaging atmospheric Cherenkov telescopes (IACTs) located in the Khomas highland in Namibia. It was built to detect Very High Energy (VHE, >100 GeV) cosmic gamma rays. Since 2003, H.E.S.S has discovered the majority of the known astrophysical VHE gamma-ray sources, opening a new observational window on the extreme non-thermal...
Abstract submitted by Aldo PENZO
Due to extremely high rates near the intense LHC interacting beams, forward regions of LHC experiments are challenging for most detectors, that need to have superior time resolution and radiation resistance. Detectors based on Cherenkov light produced in quartz elements meet these requirements and are ideal components for forward calorimeters.
For instance...
An array of $8 \times 8$ silicon photomultipliers (SiPMs) was characterised as a position sensitive single photon sensor for Ring Imaging Cherenkov (RICH) counter. To improve the geometric efficiency of the array, light concentrators were designed in a form of truncated pyramids and machined from borosilicate glass. A very high number of photons per Cherenkov ring, approximately 35, was...
The detector architecture consists in a hybrid MPGD combination:
two layers of Thick-GEMs (THGEM), the first of which also acts
as a reflective photocathode thanks to a CsI film is deposited
on its top face, are coupled to a bulk MICROMEGAS with pad
segmented anode kept at positive high voltage (HV), while the
micromesh is grounded; the signals are read-out via capacitive
coupling from a...
The TOP detector of the Belle II Experiment at KEK is a particle
identification detector, devoted mainly to the separation of charged pions
and kaons.
Principle of operation of the TOP is the total internal reflection of
Cherenkov photons emitted by charged particles while crossing a quartz
radiator. The Cherenkov photons are then detected by an array of micro-cannel plate
photomultipliers,...
The RICH detector of the HADES experiment is designed for efficient electron identification (electron momenta up to few hundred MeV/c) in relativistic heavy ion collisions, and successfully in operation since 1999 at the SIS18 accelerator facility, GSI, Darmstadt, Germany. It is based on a gaseous photon detector with a reflective CsI cathode deposited on the MWPC pad plane.
The CBM experiment...
