disrupted beam tracking studies of heavily disrupted post-collision electron beams. We find that the two codes in
most cases give an equivalent description of the beam transport.
The ILC Beam Dumps
The baseline configuration of the International
Linear Collider requires 2 beam dumps
per interaction region, each rated to 18MW of
beam power, together with additional beam
dumps for tuning purposes and machine

protection. The baseline design uses high pressure moving water dumps, first developed for the SLC and used
in the TESLA design, although a gas based dump is also being considered. In this paper we discuss the progress
made by the international community on both physics and engineering studies for the beam dumps.
A Laser-wire System at the ATF Extraction Line
A new laser-wire system has been installed
at the ATF extraction line at KEK, Tsukuba.
The system aims at a micron-scale laser spot
size and employs a mode-locked laser system.
The purpose-built interaction chamber,
light delivery optics, and lens systems are
described, and the first results are presented.

A Study of Laser System Requirements for Application in Beam Diagnostics and Polarimetry
at the ILC
Advanced laser systems will be essential for
a range of diagnostics devices at the ILC.
High average power, excellent stability and
reliability will be crucial in order to deliver
the information required to attain the necessary
ILC luminosity. The key parameters
are listed together with the R&D required
to achieve the necessary laser system performance.
