In the Very Forward Region of the detectors for the International Linear Collider two
subsystems will be situated: LumiCal and BeamCal. These detectors cover a polar angle
range from 82 mrad down to a 4 mrad. LumiCal and BeamCal give the possibility of the
detection of single high energetic particles in their coverage region. Despite this a
precise measurement of the total luminosity will...

A way to determine luminosity at ILC is to measure Bhabha scattering in the
LumiCal. For physics requirements, one needs to reach a precision of 10^-4 for the
luminosity determination and thus the Bhabha cross section. Whereas studies on
theoretical uncertainties on the cross section and on mis-identified Bhabhas in the
LumiCal are fully performed, bias on Bhabha measurement due to...

The bunch fields at the interaction point of the ILC have a dominant effect on
background pair production. The Breit-Wheeler, Bethe-Heitler and Landau-Lifshitz
processes have all been studied in detail. The number of background pairs per bunch
crossing due to these processes is well known. However the effect of the bunch fields
on the Breit-Wheeler process has not been calculated. This...

We have performed a detailed study of the power losses along the post-collision
extraction line of a TeV e+e- collider with a crossing angle of 20~mrad at the
interaction point. Five cases were considered: four luminosity configurations for ILC
and one for CLIC. For all of them, the strong beam-beam effects at the interaction
point lead to an emittance growth for the outgoing beams, as...

The complete optics design for the 2mrad crossing angle interaction region and
extraction line was presented at Snowmass 2005. Since this time, the design task
force has been working on developing and improving the layout. The work has focused
on optimising the final doublet (including by using higher gradient magnet
materials), on reducing the power losses resulting from the disrupted...

The StaFF (Stabilisation of Final Focus) system will use interferometers to monitor
the relative positions of several key components in the beam-delivery and interaction
region. The most demanding application will be the relative position monitoring of
the ILCs final focus quadrupole magnets; whose mutual and beam-relative stability,
will have a direct impact on detector...

For the design of the ILC a polarised positron source based on a helical undulator
system has been proposed. In order to optimise the positron beam, i.e. to ensure
high intensity as well as high degree of polarisation, a measurement of the
polarisation close to the positron creation point is envisaged.
In this contribution methods to determine the positron polarisation at low...

The full exploitation of the physics potential of an International Linear Collider
(ILC), will require the development of polarized positron beams. Having both
positron and electron beams polarized will be a decisive improvement for
many physics studies in the linear collider, providing new insight into
structures of couplings and thus access to the physics beyond the standard
model. The...
