The eighth CTF3 collaboration meeting was held at CERN on 30th September and 1st October 2003. All collaborating institutes participated: LNF (Frascati), LAL (Orsay), RAL (Oxford), SLAC (Stanford) and Uppsala University. This year a new collaboration partner (North Western University Illinois) participated for the first time. In addition many CERN groups made important contributions.
Important results from operation of the Preliminary phase - the bunch combination by a factor of 4 and 5 - were reported, an important proof of principle for the CLIC Drive Beam scheme.
A highlight of the commissioning of the Initial phase was the successful operation of the accelerating structures with 100 % beam loading with nominal beam parameters.
Impressive progress was reported on all activities. The design and layout studies are far advanced and very active hardware design and prototyping is going on. Series production of many components has already started.
The major milestones for 2004 are the installation and commissioning of the Drive Beam Accelerator followed by the magnetic chicane and a 30 GHz high power RF test stand in the linac. For 2005 the installation of the Delay Loop is planned.
