ISA meeting

Week 11, March 14, 2000.

Status of the ring: ASTRID is still running well: We have about 200 mA of stored beam almost every morning, and the lifetime is such, that there is about 100 mA left after 24 hours! Monday, we tried to leak Argon into the ring, but saw no improvements in injection. This was an attempt to simulate a 'new' ring, in which the vacuum is often less than ideal.

The EBIS has now been running with an electron beam for 2 weeks, and the vacuum has improved. With gas injection of Ne, charge states 1 to 6 are dominating over the residual gas spectrum, and there is about 1 microamp in the pulse. This is now being mass separated in the 'Risø' magnet, in order to determine the content of each charge state.

ELISA is now taken apart in order to have the new cylindrical electrodes mounted.

Welcome to Nykola Jones from University College London. Nykola is employed in a post doc position, and will be working with SL and DF initially for 1 year.
