The PosiPl 2008 is joinly hosted by


KEK High Energy Accelerator Research Organization


Hiroshima University

The PosiPol is a series of workshops dealing with the physics
aspects, the suggestions and the open questions concerning
a polarized positron source in the framework of the ILC and
CLIC projects. The PosiPol 2008 is the third workshop
following Posipol 2006 at CERN and 2007 at LAL, Orsay.

A primal topic of the workshop is the polarized positron source
by laser Compton back-scattering schemes and attention will be
paid to a comparison between the Compton and the undulator
baseline solution.
However, conventional positron sources with various target material,
such as metal, liquid metal, and crystal, for the linear colliders
will also be topics of the workshop.


The meeting will also focus on the development and coordination
of the R&D programs under way and the need for a costing of
the different solutions.

This workshop is addressed not only to experts and participants
in the ILC and CLIC projects, but also to a wider audience and
may prove of particular interest to the community studying the
application of the Compton radiation source to the industrial and
medical field.
