"Impact of new CLIC parameters on bunch compressors and turn around loop"
I report on the implications of the new CLIC parameters on beam dynamics in the main beam bunch compressors  as well as in the drive beam bunch compressors and the turn around loop. First a short overview on the status of  the beam lines before the parameter change is given, followed by a comparison of old versus new parameters.  I discuss the expected influence of the new parameters on CSR emittance growth in the aforementioned beam lines  and will present first results of beam dynamics simulation using them. An outlook is given on the work required to adapt the beam line layouts and optics functions to the new conditions. Some open questions regarding the new parameter set are identified.

"Summary of POSIPOL 07 workshop"
The POSIPOL 07 workshop, concerning the production of polarized positron for the ILC and CLIC, was held in Orsay in May 2007. The ILC reference scheme is based on the undulator. However alternative options are strongly under studies (Compton ring, Linac, ERL). CLIC is considering these different options. A brief overview of the workshop, with the related recommendations, will be presented.
