The PANDA experiment, part of the planned FAIR upgrade to GSI,
Darmstadt, will aim to study modern hadronic physics with unprecedented
accuracy and precision. Excellent particle identification of both
charged and neutral particles is necessitated to achieve PANDA's
physics aims. Two Detection of Internally Reflected Cherenkov (DIRC)

Cherenkov imaging in particle and nuclear physics experiments
Poster
Correlation phenomena occurring in Cherenkov radiation are considered which are related to fluctuations of the charge states of multiply charged accelerated ions in a medium. The additional correlation contribution to the radiation is determined by the root-mean-square deviation of the ion charge from its equilibrium value and is responsible for the nonzero radiation yield in the event that...

at the COSY proton storage ring in Juelich. The purpose of this counter
is to improve for 400 MeV to 800 MeV protons the kinetic energy measurement
in the forward direction, measuring their speed at the few per mille level.
The disc DIRC is to be placed downstream of the WASA tracking counters
in front of stacked...

An important experimental direction of the study in physics of heavy ion collisions is the measurement of the yield of high-Pt particles. The main problem is to study the dominant mechanism of parton energy loss in compressed nuclear matter. “Jet quenching effect” by RHIC STAR and PHENIX Collaborations gives the indication that there is a different loss of energy by quarks and gluons in a...

A key observable of the Compressed Baryonic Matter (CBM) physics program is a precise measurement of low-mass vector mesons and charmonium in their leptonic decay channel. In the CBM experiment at FAIR, electrons will be identified using a gaseous RICH detector combined with several TRD detectors positioned behind a system of silicon tracking stations. The concept of the RICH detector foresees...

The PANDA experiment at the future facility for anti-proton and ion research (FAIR) at GSI, Darmstadt, aims at studying the strong interaction by precision spectroscopy. A detector system with excellent particle identification (PID) properties over a large range of solid angle and momentum is therefore mandatory. For the charged hadron identification in the barrel region, a compact ring...

Silica aerogel blocks are produced for use in Cherenkov detectors by a collaboration of Boreskov Institute of Catalysis and Budker Institute of Nuclear Physics since 1986. Novosibirsk aerogel is used in several detectors. Among them are KEDR (BINP, Novosibirsk), LHCb (CERN, Geneva), AMS (for International Space Station mission) and others.
Currently our investigations are aimed at two...

Imaging Cherenkov detectors play an important role in modern particle and nuclear physics experiments.
DIRC-type Cherenkov counters offer the advantage of a very compact detector design by employing solid
radiator materials. The optical quality of such materials is paramount and has to withstand the radiation
environment of modern high luminosity experiments without significant...

Cooled antiproton beams of unprecedented intensities in the momentum
range of 1.5-15 GeV/c will be used at the PANDA experiment at FAIR to
perform QCD studies including searches for exotic states and high precision
experiments in the charmed quark sector.

The LHCb experiment plans to operate at an LHC luminosity of 2x10**32 /s cm2,
or typically one collision per bunch crossing.
After about five years it will have recorded a data sample of 10 fb-1.
At this time LHCb plans an upgrade to operate the detectors at a
significantly increased luminosity that will extend greatly its
potential for discovery and study of new phenomena.
The key...
