The ALICE Central Trigger Processor (CTP) has been upgraded for LHC Run 2, amongst other motivations in order to improve the data-taking efficiency for the Transition Radiation Detector (TRD).
There is also a new CTP interaction record with a new DDL link , a 2 GB SODIMM DDR3 memory, an extension of the number of clusters and an extension of functionality for classes. The CTP switch has been...

The ATLAS New Small Wheel (NSW), comprising MicroMegas (MMs) and small-strip Thin Gap Chambers (sTGCs), will upgrade the ATLAS muon system for a high background environment. Particularly, the NSW trigger will reduce the rate of fake triggers coming from background tracks in the endcap. We will present an overview of the NSW trigger processor, the sTGC and MM trigger algorithms, and the...

The ATLAS Level-1 Central Trigger system is responsible for forming the level-1 trigger decision based on the information from the calorimeter and muon trigger processors. It has undergone a major upgrade of its key components to cope with the increase of luminosity and physics cross-sections in Run 2. In this presentation, we give an overview of the commissioning and the overall performance...

The ATLAS Fast TracKer (FTK) is a custom electronics system that will operate at the full Level-1 accept rate, 100 kHz, to provide high quality tracks as input to the High-Level Trigger. The event reconstruction is performed in hardware, thanks to the massive parallelism of associative memories (AM) and FPGAs. We present the advantages for the physics goals of the ATLAS experiment and the...

SuperNEMO is the next-generation (0νββ) experiment based on a tracking plus calorimetry technique. The demonstrator is made of a calorimeter (712 channels) and a tracking detector (6102 channels). These detectors front-end electronics use an unified architecture. The trigger system has for the calorimeter part 2 trigger thresholds, for the tracker part the possibility of a second triggering...

The ATLAS level-1 calorimeter trigger pursues a series of upgrades in order to face the challenges posed by the upcoming increase of the LHC beam energy and luminosity. The hardware built during the Phase-1 upgrade will be installed in 2018. The calorimeter data will be available with a tenfold increase of granularity which allows to employ more sophisticated identification algorithms. To cope...

The High Luminosity LHC (HL-LHC) will deliver luminosities of up to 5x10^34 cm^2/s, with an average of about 140 overlapping proton-proton collisions per bunch crossing. These extreme pileup conditions place stringent requirements on the trigger system to be able to cope with the resulting event rates. A key component of the CMS upgrade for HL-LHC is a track trigger system which would identify...
