ESLEA Task E1: VLBIProject Definition Document v 5.0

33 .. PPRROOJJ EECCTT DDEEFFIINN II TT IIOONN 3.1 TASK E1OVERVIEW

This task brings two of the most network-intensive application areas, High Energy Physics (HEP) and VeryLong Baseline Interferometry (VBLI), onto the switched optical network. The demonstration of benefits tothese two applications would represent a major success in UKLight exploitation.

Two HEP application areas are involved in Task E1: Collider Detector at Fermilab (CDF) and A Toroidal

LHC ApparatuS (ATLAS). The next generation of collider experiments will produce datasets measured inPetabytes per year that can only be processed and analysed by globally distributed computing resources.High-bandwidth data transport between federated processing centres is therefore an essential componentof the reconstruction and analysis chain.

CDF is a particle physics experiment trying to elucidate the fundamental nature of matter. It is presentlytaking data from proton anti-proton collisions at the worlds highest energy colliding beam facility, theTevatron at Fermilab, Chicago. This data is being analysed by almost 800 physicists located at 61

institutions in 13 countries in three continents. In order to effectively utilise the distributed computingfacilities of this network, it is necessary to have h
