[esa-t474] EPAC abstracts submitted

[Alexey Lyapin]

Hi Everyone,

Here are the two abstracts I've submitted to EPAC. You have 1 more day 
to criticise me for not including some or including too many people and 
correcting the text.

Cheers,
Alex


1. (#2995) In Linear Colliders section

Title: 	ILC Energy Spectrometer Development
Presenter: 	Alexey Lyapin - University College London Department of 
Physics and Astronomy
Authors: 	Alexey Lyapin, Filimon Gournaris, Bino Maiheu, David John 
Miller, Matthew Wing (UCL, London), Heinz Juergen Schreiber, Michele 
Viti (DESY Zeuthen, Zeuthen), Sergey Kostromin, Nikolay Morozov (JINR, 
Dubna, Moscow Region), Michael Hildreth (Notre Dame University, Notre 
Dame, Iowa), Stewart Takashi Boogert, Gary Boorman (Royal Holloway, 
University of London, Surrey), Chris Adolphsen, Ray Arnold, Douglas 
McCormick, Jonny S.T. Ng, Zen Szalata, Mike Woods (SLAC, Menlo Park, 
California), Frank Jackson (STFC/DL/ASTeC, Daresbury, Warrington, 
Cheshire), Maria Vladimirovna Chistiakova, Yury G. Kolomensky, Erik 
Petigura (UCB, Berkeley, California), Mark Slater, David Ward 
(University of Cambridge, Cambridge)

The next TeV scale electron machine for high energy physics research 
will for obvious reasons be a linear collider. One of the key beam 
parameters affecting the physics measurements is the average energy of 
the particles in interacting bunches, and in case of the linear collider 
it can only be determined by a dedicated instrument. We have been 
working on an energy spectrometer based on a magnetic chicane to deliver 
the required accuracy of 10e-4. In this paper we review the recent 
results of our experiments and simulations.

2. (#2664) In Instrumentation section

Title: 	BPM System for the ILC Energy Spectrometer
Presenter: 	Alexey Lyapin - University College London Department of 
Physics and Astronomy
Authors: 	Alexey Lyapin, Derek Attree, Bino Maiheu, Matthew Wing (UCL, 
London), Michael Hildreth (Notre Dame University, Notre Dame, Iowa), 
Stewart Takashi Boogert, Gary Boorman (Royal Holloway, University of 
London, Surrey), Chris Adolphsen, Ray Arnold, Douglas McCormick, Jonny 
S.T. Ng, Zen Szalata, Mike Woods (SLAC, Menlo Park, California), Maria 
Vladimirovna Chistiakova, Yury G. Kolomensky, Erik Petigura (UCB, 
Berkeley, California), Mark Slater, David Ward (University of Cambridge, 
Cambridge)

Independently of the technology used and the time scale of R&D work, the 
next linear collider will certainly be a collection of technical 
challenges. The energy spectrometer is not an exception - it will be 
required to provide an energy measurement accurate to 10e-4 or better 
over periods of multiple ours and days. In this paper we report on our 
studies of the hardware solutions able to provide the required 
resolution and stability. We also give some details on our work to 
simulate the behaviour, process the signals and analyse the data 
generated by one of the main components - beam position monitors. One of 
the results of this work is the first version of the software library 
containing a set of helpful BPM simulation and analysis tools - libbpm, 
which we recently made available for the community.
