6. Simulation studies on precise timing information during High Luminosity LHC at the CMS experiment.

Mr Luca Pernie (Universite Libre de Bruxelles (BE))

04/03/2015, 17:08

We present prospects for the usage of precise timing information during the high luminosity phase of the LHC, where the instantaneous luminosity is estimated to be greater than 10^34 cm-2s-1, resulting in about 140 simultaneous proton-proton (pileup) collisions that occur every 25 nsec. It is shown that time information could be exploited for the association of photons to their collision...

28. The CMS Data Quality Monitoring software: experience and future improvements

Atanas Ivanov Batinkov (University of Sofia (BG))

The Data Quality Monitoring Software proved to be a central tool in the Compact Muon Solenoid experiment. Its flexibility allowed its integration in several environments: online, for real-time detector monitoring; offline, for the final, fine-grained data certification. The usage of the Data Quality Monitoring software in the different environments and its integration in the Compact Muon...

27. CMS Alignment and Calibration Workflows:Lessons Learned and Future Plans

Salvatore Di Guida (Universita degli Studi Guglielmo Marconi (IT))

04/03/2015, 17:10

We review the online and offline workflows designed to align and calibrate the CMS detector. Starting from the gained experience during the first LHC run, we discuss the expected developments for Run II. In particular, we describe the envisioned different stages, from the alignment using cosmic rays data to the detector alignment and calibration using the first proton-proton collisions data (...

29. Upgrade of the TOTEM DAQ for the LHC's Run Two

Michele Quinto (Universita e INFN-Bari (IT))

Data acquisition systems in High Energy Physics process data produced by particle detector at colliders or fixed target experiments. With the LHC era collisions are produced at the bunch crossing rate of 40MHz. Data volumes and trigger rates pose requirements for Data Acquisition Systems. The TOTEM Experiment at the LHC collider measures total p-p cross section at the accelerator energies and...

33. CMS Level 1 trigger upgrade and its performance for Run 2 Heavy Ion data taking

38. The ATLAS Tile Calorimeter for Run II and towards Phase II

Leonor Cerda Alberich (Instituto de Fisica Corpuscular (ES))

04/03/2015, 17:14

This poster will present the status of the ATLAS Tile Calorimeter at the beginning of the LHC Run II, with emphasis on the electronics consolidation during LS1 and recent operation experience with cosmics. The status of the Phase II upgrade R&D will also be briefly presented.

40. Getting the ATLAS IBL detector ready for Run 2 data taking

Laura Franconi (University of Oslo (NO))

The Insertable B-Layer was inserted in May 2014 in the centre of the ATLAS detector. This new layer will enhance the tracking robustness of the inner detector, improve the vertexing and b-tagging capabilities and preserve the high performance of the Pixel detector, in spite of the radiation damage, particularly important in the B-Layer. The poster presents an overview of the structure of the...

57. Demonstrator for the ATLAS LAr calorimeter Phase-I Trigger Readout Upgrade

Adriana Milic (CERN)

04/03/2015, 17:16

From 2019 – 2021, during Run 3, the LHC will achieve luminosities of about L ~ 2.2×10^(34) cm−² s−¹ and an integrated luminosity of ~ 300 fb−¹ is expected. In order to exploit the higher luminosity while keeping the same first level trigger bandwidth of 100 KHz, higher transverse granularity and depth information for the ATLAS Liquid Argon (LAr) Calorimeter Trigger is required.

69. The Evolution of the Region of Interest Builder in the ATLAS Experiment

Othmane Rifki (University of Oklahoma (US))

04/03/2015, 17:17

ATLAS is a general purpose particle detector at the Large Hadron Collider (LHC) at CERN designed to measure the products of proton collisions. Given their high interaction rate (1GHz), selective triggering in real time is required to reduce the rate to the experiment’s data storage capacity (1KHz). To meet this requirement, ATLAS employs a combination of hardware and software triggers to...
