An FPGA based Topological Processor Prototype for the ATLAS Level-1 Trigger Upgrade
2012
By 2014 the LHC will collide proton bunches at 14TeV with an increased instantaneous luminosity up to 3·10³⁴cm⁻²s⁻¹. The resulting higher event rate will challenge the existing ATLAS trigger system. A reduction on the trigger rate can be achieved by selecting interesting channels based on their expected decay topology and thus reducing background. This will be achieved by introducing of a new FPGA based module in the Level-1 trigger: the Topological Processor L1Topo. With L1Topo it will be possible for the first time to concentrate detailed information from the entire calorimeters and the muon detector into a single module. L1Topo will receive a total aggregate bandwidth of 1Tb/s. The data …
Upgrade of ALICE forward detectors
2019
ALICE will upgrade its subsystems in 2019−2020 to fully benefit from the increased collision rate and luminosity of the LHC at CERN. Two new forward detectors will be installed at the core of ALICE: the Fast Interaction Trigger (FIT) and the Muon Forward Tracker (MFT). Additionally, during the shutdown between Run 3 and Run 4, there will be an opportunity to install the Forward Calorimeter (FoCal). This paper describes these new forward detectors, their physics justification and goals, selected design features along with performance of detector prototypes and simulated performance figures. peerReviewed
Ultrascale+ for the new ATLAS calorimeter trigger board dedicated to jet identification
2018
To cope with the expected increase in luminosity at the Large Hadron Collider in 2021, the ATLAS collaboration is planning a major detector upgrade to be installed during Long Shutdown 2. As a part of this, the Level 1 trigger, based on calorimeter data, will be upgraded to exploit the fine granularity readout using a new system of Feature EXtractors (FEXs), which each reconstruct different physics objects for the trigger selection. The Jet FEX (jFEX) is one of three FEXs and has been conceived to identify small/large area jets, large area tau leptons, missing transverse energy and the total sum of the transverse energy. The use of the latest generation Xilinx Field Programmable Gate Array …
Upgrade of the ATLAS Central Trigger for LHC Run-2
2015
The increased energy and luminosity of the LHC in the run-2 data taking period requires a more selective trigger menu in order to satisfy the physics goals of ATLAS. Therefore the electronics of the central trigger system is upgraded to allow for a larger variety and more sophisticated trigger criteria. In addition, the software controlling the central trigger processor (CTP) has been redesigned to allow the CTP to accommodate three freely configurable and separately operating sets of sub detectors, each independently using the almost full functionality of the trigger hardware. This new approach and its operational advantages are discussed as well as the hardware upgrades.

Révision spécifique des campagnols du sous-genre Microtus (Terricola) (Mammalia, Rodentia) de l'abri Mochi (Ligurie, Italie).
2010
8 pages; National audience; Une nouvelle analyse morphométrique de la population des campagnols du sous-genre Microtus (Terricola) de l'Abri Mochi (Ligurie, Italie), comparée à de nouvelles populations de référence de M. (T.) multiplex et M. (T.) savii, aboutit à une révision de leur appartenance spécifique en les attribuant exclusivement à M. (T.) multiplex. Comparée aux populations liguriennes actuelles de M. (T.) multiplex, la population gravettienne de l'Abri Mochi se caractérise par une petite taille et une boucle antérieure ouverte. L'isolement géographique de la population probablement lié à une phase climatique froide, semble être l'explication la plus probable de cette divergence o…
