ISA meeting

Week 48, Nov. 24, 1998.

Status of the ring: The injection beamline is now ready. It looks good: we have good transmission, and have had stored beam in the ring.
We started with an Argon beam in order to test injection, storage and acceleration with the new beamline and control system, and the only problem has been with the FAF-system, which generates the RF-frequency. The frequencies were not completely synchronous with the dipole field changes, but the problem has been identified, and is being solved.
We hope to be able to accelerate later today, after which we will set up a ¹³C¹⁶O⁺⁺ beam for the electron cooler group.

The new control system has performed very well during the past week, in which all parts of it have been used. It is a significant improvement compared to the old one.

The microtron had the o-ring in one of the main dipoles changed. It is now under vacuum again, and it looks good. A new type of o-ring has been used, which is slightly larger then the old one, and which should be more resistant to radiation damage.

ELISA is now running various metal clusters, and is performing very well. It is extremely well suited for this type of study due to the good vacuum and electrostatic optics, which allow all ions to be run at a given energy with the same ring settings.

The SGM II success will be celebrated this afternoon at 14:00 in the ring hall, outside ASTRID. There will be drinks and snacks.
