IOPP Forum:Dr.Weiming Qian 3:00PM, Dec.8,2016, Thursday

Time:3:00PM, Dec.8,2016, Thursday

Venue:Room 9409

Speaker:Dr.Weiming Qian (Rutherford Appleton Laboratory)

Abstract:This presentation consists of two parts. The first part gives a brief introduction of the Science & Technology Facilities Council of the UK, including its programmes and facilities with a focus on the challenging technologies needed for world-class scientific research. The second part is about the Phase-I Upgrade of the Level-1Trigger system of the ATLAS experiment at CERN. Rutherford Appleton Lab played a critical role in the original ATLAS Level-1 trigger system design, which has been running successfully since 2009 and led to the discovery of Higgs-boson in 2012. Starting in 2021, the LHC luminosity will double, which will increase the pileup rate. However, the ATLAS front-end detector electronics will remain largely unchanged. Hence the total ATLAS Level-1 Trigger rate will still be limited by the readout bandwidth of the front-end electronics to 100 KHz or less. Moreover, the Level-1 Trigger must retain sensitivity to the physics electroweak processes and stay within the current ATLAS Level-1 latency envelope of 2.5µs. To meet these new challenges, the Phase-I Upgrade to the ATLAS Level-1 Trigger system is needed. The focus of the second half of this presentation is on the overall architecture of the Phase-I Upgrade, the trigger algorithms and performance, the prototype design and test results.
