9. The ALICE trigger electronics

Marian Krivda (University of Birmingham, UK)

Oral

The ALICE trigger system (TRG) consists of a Central Trigger Processor (CTP) and up to 24 Local Trigger Units (LTU) for each subdetector. CTP receives and processes trigger signals from trigger detectors and output from CTP are 3 levels of hardware triggers L0, L1 and L2. 24 trigger detectors are dynamically partitioned into up to 6 independent clusters. The trigger information is...

22. Data transmission and selection for the L0 calorimeter trigger of LHCb.

Mr Giulio Avoni (Istituto Nazionale di Fisica Nucleare (INFN))

Oral

This report describes the Selection Crate, designed by INFN for the L0 calorimeter trigger of the LHCb experiment. The Selection Crate is a modular system which consists in 8 Selection Boards (SB) used to select the most energetic clusters detected by the electromagnetic and hadron calorimeters, as well to evaluate other global trigger variables. A SB is equipped with 28 x 1.6 Gbps...

81. A first-level track trigger architecture for Super-CMS

Dr Dave Newbold (University of Bristol / Rutherford Laboratory)

Oral

We present a first architectural study of a first-level hardware track trigger for CMS at SLHC. The design of a hardware track trigger at 10^35cm-2s-1 is challenging. A primary constraint on implementation will be power consumption within the detector, in turn driven by the data transmission bandwidth to off-detector electronics. We therefore emphasise the minimisation of the data flow through...
