LHCb - Large Hadron Collider beauty experiment

http://lhcb-public.web.cern.ch/lhcb-public/en/Data%20Collection/Triggers-en.html

LHCb - Large Hadron Collider beauty experiment. When LHCb is up and running, the detector will register an estimated 10 million proton collisions every second. Recording all of these ‘events’ is virtually impossible due to limited storage capacity. So, in order to cherry-pick the best of them, LHCb employs an electronic system called a ‘trigger’. The LHCb trigger system operates on two levels. The first uses information taken in real-time from the detector – specifically from the VELO. And the muon system.

http://lhcb-public.web.cern.ch/lhcb-public/en/Detector/VELO-en.html

LHCb - Large Hadron Collider beauty experiment. The LHC proton beams pass through the full length of the detector, safely encased within a beryllium pipe. The only point where the beams collide, and particles containing b and anti-b quarks are produced, is inside the VELO sub-detector. The VELO measures the distance between the point where protons collide (and where B particles are created) and the point where the B particles decay, spraying out other particles that VELO can detect. The B particles a...

Journal Club: Indiana University Dept. of Physics. Organized by Chuck Horowitz. Sunday, October 28, 2007. Journal Club next week. Next week Heechang will discuss about b physics focusing on CP violations. It will be kind of review of CP violations, and CKM matrix stuff. Some new experimental issue of b physics, including LHC-b will also be discussed. The reference: http:/ lhcb-public.web.cern.ch/lhcb-public/. Subscribe to: Post Comments (Atom). Please come for the food and for the good discussion.

Scientific Committees, Schools and Meetings. The current experimental programme at CERN is summarized in the electronic version of the Grey Book. The experiments listed there use one of the following machines: the Large Hadron Collider ( LHC. With energy up to 14 TeV, the most powerful accelerator in the world; the 400 GeV Super Proton Synchrotron ( SPS. Which now acts as an injector for the LHC, but also hosts fixed-target experiments and provides test beams; the 28 GeV Proton Synchrotron ( PS. Group st...

The old Trigger home page, quite obsolete, can be accessed here. The LHCb Trigger has three levels:. A hardware level reducing the rate to 1 MHz in 4 μs. Level-1, a software level using selected data, reducing the rate to 40 kHz with about 1 ms processing time. A software level running on the whole event, with an output rate up to 2 kHz and 10 ms processing time. Three projects (or sub-projects) are working together to provide the LHCb trigger. Handles the hardware and software of the Level 0 trigger.
