The Mark-ii Data Acquisition and Trigger System*
The Mark-II Data Acquisition and Trigger system requirements and general solution are described. The solution takes advantage of the synchronous crossing times and low event rates of an electron positron collider to permit a very highly multiplexed analog scheme to be effective. The system depends on a two level trigger to operate with acceptable dead time. The trigger, multiplexing, data reduc...
متن کاملUse of Network Processors in the LHCb Trigger/DAQ System
Network Processors are a recent development targeted at the high-end network switch/router market. They usually consist of a large number of processing cores, multi-threaded in hardware, that are specialized in analysing and altering frames arriving from the network. For this purpose there are hardware co-processors to speed-up e.g. tree-lookups, checksum calculations etc. The usual application...
متن کاملLHCb trigger streams optimization
The LHCb experiment stores around 10 collision events per year. A typical physics analysis deals with a final sample of up to 10 events. Event preselection algorithms (lines) are used for data reduction. Since the data are stored in a format that requires sequential access, the lines are grouped into several output file streams, in order to increase the efficiency of user analysis jobs that rea...
متن کاملThe LHCb Trigger Strategy and Performance
We give an outline of the LHCb trigger strategy and performance. The first and second levels (called L0 and L1) are discussed in some detail, while the subsequent Higher Level Trigger (HLT), which is currently under development, is only briefly described.
متن کاملData Acquisition and Trigger Considerations
This note discusses requirements on data acquisition and triggering for the UT Maya Muon detector. The detector is described in a conceptual design report [1] (CDR). The present discussion is limited to the tracking system which is used to form event triggers and to measure muon trajectories; data from the Cherenkov system will be read out and recorded when a trigger generated by the tracking s...
