A RICH Multiplicity Veto for the HERA-B Experiment
We present the design and commissioning of a new multiplicity veto for the HERA B detector, a fixed-target spectrometer originally designed to study the physics of B mesons in proton-nucleus interactions. The HERA B trigger is a message-driven multi-level track trigger. The first level trigger (FLT) consists of custom-made electronics, and the higher trigger levels are implemented as PC farms. ...
متن کاملA High-pt Trigger for the Hera-b Experiment
We have constructed a high-pT trigger for the HERA-B experiment at DESY. The HERA-B experiment produces B mesons by inserting wire targets into the halo of the proton beam circulating in HERA. The high-p T trigger records events that contain tracks that have high transverse momentum with respect to the beam. Such a trigger is efficient for recording B → ππ, B → Kπ, Bs → K K, Bs → D − s π , and ...
متن کاملQuarkonia production with the HERA B experiment
Abstract. Measurements of the dependence of the J/ψ production cross section on its kinematic variables as well as on the target atomic numbers for 920 GeV/c protons incident on different targets have been made with the HERA B detector. The large collected di-lepton sample allows to study the production ratio of ψ(2S) to J/ψ and of χc to J/ψ. We also report on measurements of the bb and Υ produ...
متن کاملFarming in the HERA-B Experiment
The HERA-B data acquisition and triggering systems make use of Linux PC farms for triggering and online event reconstruction. We present in this paper the requirements, implementation and performance of both PC farms. They have been fully working during the 2000 detector and trigger commissioning run.
متن کاملHigher Level Trigger Systems for the HERA-B experiment
The HERA-B experiment[1, 2] is designed for observation of CP violation in the B-meson system at the HERA machine in DESY. The data acquisition and triggering system must cope with a half million detector channels, a 40 MHz interaction rate and a signal to background ratio of 10 10. A highly selective multi-level trigger and high bandwidth data acquisition system has been designed and is curren...
