Louis stated that the working group had parallel sessions at times and that there was not enohg time for discussion except for the very end when a number of participants had already left. Bunch compressors were not discussed as people assumed that there is no problem. There was hardly any progress on polarised RF guns. The surface charge limit has been overcome for electron sources, and the NLC demonstrated a charge compatible with 78% polarisation. Multi-bunch electron production remains to be realised. People at NLC are worried about their target for positron production because the SLC one broke. They are also investigating a micro undulator for a TESLA-like positron source. At KEK and CERN, there has been some progress using channeling in crystals for positron production. It was stated that there is good confidence that the damping rings for each of the projects can meet the requirements. At the same time, a number of problems is still not solved and may lead to design changes; among them are collective effects and R&D in all areas of instrumentation. Also demonstration of the required vertical emittance is lacking.
Gilbert informed about working group 5 in which the site evaluations, civil engeneering, construction plans, power handling, operation and reliability were discussed. Tunnel layouts exist for all projects and for a number of sites ground motion measurments have been performed. Experiments of the stabilisation of elements agains vibrations are ongoing in different labs. The total power consumption of the NLC and the JLC are quite high, about 180MW for NLC and 250MW for JLC, some overhead needs to be foreseen in the installations. The usefulness of the global accelerator network (GAN) was also discussed with split opinions. At least, a common conclusion seems to have been the the GAN would not suffice to justify the staffing in the non-host laboratories.
