Event Logging and Distribution for the BaBar Online System
We discuss the BABAR experiment software and computing infrastructure used for event logging and distribution to prompt reconstruction system. The raw data for typical BABAR events is about 30-50 kB per event. During the data taking a 100 Hz stream of events is collected from a farm of 32 online computers amounting to about 3-5 MB/s. A robust and efficient multi-threaded, TCP/IP based logging m...
متن کاملBaBar Level-1 Drift Chamber Trigger Upgrade
submitted to the Xth VCI 2004 30 November 2003 This BaBar L1 DCT upgrade is essential for improving L1 trigger background rejection in preparation for the expected increase in PEP-II luminosity. A large fraction of the current L1 trigger background come from interactions of beam particles with beam line components at ∼ ±20 cm from the interaction point (IP), along the beam direction (z axis). T...
متن کاملCMS Calorimeter Trigger/Readout Electronics for SLHC
The SLHC will be a very challenging environment for physics and for the trigger and DAQ in particular. Expected pileup multiplicies on the level of 40-200 interactions every beam crossing will flood the detector with the “ambient noise” of many low pT particles. The impact of these low pT particles is particular large for the hadron calorimeter, which has a relatively large cell size (compared ...
متن کاملReadout and Trigger for the AFP Detector at ATLAS Experiment
AFP, the ATLAS Forward Proton consists of silicon detectors at 205 m and 217 m on each side of ATLAS. In 2016 two detectors in one side were installed. The FEI4 chips are read at 160 Mbps over the optical fibers. The DAQ system uses a FPGA board with Artix chip and a mezzanine card with RCE data processing module based on a Zynq chip with ARM processor running ArchLinux. In this contribution we...
متن کاملThe Redesigned BaBar Event Store: Believe the Hype
As the BaBar experiment progresses, it produces new and unforeseen requirements and increasing demands on capacity and feature base. The current system is being utilized well beyond its original design specifications, and has scaled appropriately, maintaining data consistency and durability. The persistent event storage system has remained largely unchanged since the initial implementation, and...
