[esa-t474] EPAC abstracts

[Alexey Lyapin]

Hi everyone,

I am going to submit 2 abstracts to hold the place. The deadline is this 
Monday, so will submit tomorrow late.

1. ILC Energy Spectrometer Development

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. Hardware for the ILC Energy Spectrometer

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 - the 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.

Cheers,
Alex
