Progress with ELETTRA, the synchrotron light source in Trieste

ELETTRA, the third generation synchrotron radiation source under construction in Trieste, has passed the design phase. The present schedule calls for a start of commissioning by the second half of 1993. The buildings are under construction and prototypes for all main concepts of the accelerator complex have been constructed and industrial production has started. A high-power cavity fully equipped with cooling circuit and input coupling loop, as well as mechanical tuning system, has been tested and measured. Prototype cavities equipped with higher order mode suppressors are under development. In-house prototypes for each magnet type have been built and magnetic measurements have been performed. The vacuum chamber prototype has been baked under vacuum and tested with its pumping system. A prototype pure permanent-magnet undulator has been assembled and measured. The first 100 MeV sections of the 1-5 GeV injection linac will go in operation in August 1990.<>
