The LHCb experiment has been taking data at the Large Hadron Collider (LHC) CERN since end of 2009. One its key detector components is Ring-Imaging Cherenkov (RICH) system. This provides charged particle identification over a wide momentum range, from 2–100 GeV/c. operation and control, software, online monitoring RICH system are described. performance presented, as measured using LHC. Excellent separation hadronic types (π, K, p) achieved.
The Vertex Locator (VELO) is a silicon microstrip detector that surrounds the proton-proton interaction region in LHCb experiment. performance of during first years its physics operation reviewed. system operated vacuum, uses bi-phase CO2 cooling system, and sensors are moved to 7 mm from LHC beam for data taking. stability these characteristic features described, details material budget given. calibration timing processing algorithms implemented FPGAs described. fully characterised. have...
We present the first measurement of D*(+) width using 9/fb e(+)e(-) data collected near Upsilon(4S) resonance by CLEO II.V detector. Our method uses advanced tracking techniques and a reconstruction that takes advantage small vertical size Cornell Electron-positron Storage Ring beam spot to measure energy release distribution from D*(+)-->D(0)pi(+) decay. find gamma(D*(+)) = 96+/-4 (stat)+/-22 (syst) keV. also in decay compute Delta m identical with m(D*(+))-m(D(0)) 145.412+/-0.002...
Beam test results of the radiation tolerance study chemical vapour deposition (CVD) diamond against different particle species and energies is presented. We also present beam on independence signal size incident rate in charged detectors based un-irradiated irradiated poly-crystalline CVD over a range fluxes from 2 kHz/cm2 to 10 MHz/cm2. The pulse height sensors was measured with readout electronics peaking time 6 ns. In addition functionality 3D devices demonstrated tests are shown be...
Using the CLEO-II detector, we have obtained evidence for a new meson decaying to $D^0 K^+$. Its mass is $2573.2^{+1.7}_{-1.6}\pm 0.8\pm 0.5$ {}~MeV/$c^2$ and its width $16^{+5}_{-4}\pm 3$~MeV/$c^2$. Although do not establish spin parity, consistent with predictions an $L=1$, $S=1$, $J_P=2^+$ charmed strange state.
We have studied the performance of scintillating glass fiber-optic plates using 10 GeV/c particles at SLAC test beam.

Diamond devices have now become ubiquitous in the LHC experiments, finding applications beam background monitoring and luminosity measuring systems. This sensor material is maturing to point that large pads existing diamond detectors are being replaced by highly granular tracking devices, both pixel strip configurations, for detector systems will be used Run II at beyond. The RD42 collaboration has continued seek out additional manufacturers quantify limits of radiation tolerance this...
