81. Integrated Trigger and Data Acquisition system for the NA62 experiment at CERN

Gianmaria Collazuol (INFN Sezione di Pisa (INFN))

23/09/2009, 09:45

Trigger

Oral

The TDC based integrated trigger and data acquisition system of the NA62 experiment at CERN will be presented. The system architecture, the trigger algorithm and its implementation in commercial high performance FPGAs will be described. The results of test and characterization of the custom components as well as those of extensive field tests performed on a system prototype handling up to 512...

32. A digital calorimetric trigger for the COMPASS experiment at CERN

Mr Markus Krämer (Technische Universität München)

Trigger

Oral

In order to provide a trigger for the Primakoff reaction, in 2009, the trigger system of the COMPASS experiment at CERN will be extend by an electromagnetic calorimeter trigger. Since it was decided to gain from various benefits of digital data processing, a FPGA based implementation of the trigger, running on the front-end electronics, which are used for data acquisition at the same time, is...

71. LHCb Level 0 Decision Unit

Dr Hervé Chanal (LPC Clermont-Ferrand)

Trigger

Oral

The Level 0 Decision Unit (L0DU) is one of the main components of the first trigger level of the LHCb experiment. This 16 layers custom board receives data from the calorimeter, muon and pile-up sub-triggers and computes the level 0 decision, reducing the rate from 40MHz to 1MHz. The processing is implemented in FPGA using a 40MHz synchronous pipelined architecture. The L0DU algorithm is fully...

100. PERFORMANCE OF THE CMS REGIONAL CALORIMETER TRIGGER

Mrs Pamela Renee Klabbers (University of Wisconsin-Madison)

23/09/2009, 11:25

Trigger

Oral

The CMS Regional Calorimeter Trigger (RCT) receives 8 bit energies and a data quality bit from the HCAL and ECAL Trigger Primitive Generators (TPGs) and sends it to the Global Calorimeter Trigger (GCT) after processing. The RCT hardware consists of 1 clock distribution crate and 18 double-sided crates containing custom boards, ASICs, and backplanes. The electronics for the RCT have been fully...

55. Analogue Input Calibration of the ATLAS Level-1 Calorimeter Trigger

John Morris (Queen Mary University of London)

23/09/2009, 11:50

Trigger

Oral

The ATLAS Level-1 Calorimeter Trigger is a hardware-based pipelined system using custom electronics which identifies, within a fixed latency of 2.5 us, highly energetic objects resulting from LHC collisions. It is composed of three main sub-systems. The PreProcessor system first conditions and digitises approximately 7200 pre-summed analogue calorimeter signals at the bunch-crossing rate of 40...

98. Precise Timing Adjustment for the ATLAS Level1 Endcap Muon Trigger System

Mr Yu Suzuki (KEK)

23/09/2009, 12:15

Trigger

Oral

The ATLAS level1 endcap muon trigger system consists of about 4000 Thin Gap Chambers (TGC) with 320,000 input electronics channels in order to find level1 trigger candidates for muons in both endcap regions. We had already adjusted channel-to-channel timing difference in overall TGC system with 1.2ns level, and found its consistency with the observation of beam halo events in the first proton...

95. Framework for Testing and Operation of the ATLAS Level-1 MUCTPI and CTP

Mr Ralf Spiwoks (CERN)

23/09/2009, 12:40

Trigger

Oral

The ATLAS Level-1 Muon to Central Trigger Processor Interface (MUCTPI) receives information on muon candidates from the muon trigger sectors and sends multiplicity values to the Central Trigger Processor (CTP). The CTP receives the multiplicity values from the MUCTPI and combines them with information from the calorimeter trigger and other triggers of the experiment and makes the...
