ISA meeting

Week 19, May 6, 1997.

Status of the ring: The changeover to Ion Run 1/97 is proceeding as planned. The cavity is mounted and baked, and the injection beamline and 'laser' chamber (in section 2) will be ready for pumping today or tomorrow, such that baking can be finished by Friday.
The separator is ready - VT has mounted an ion source, such that initial tests of the beam for the coming week can start Friday. We will start running Ba^- for TA & Co.

For Electron run 2/97, starting in week 32, a number of things must be made ready. These include:
X-ray microscope: Phase plate holder, shutter, MCP-translator.
The undulator beamline: Mirror chamber in front of monochromator, new 2-mirror chamber after monochromator, Interaction chamber with scanners, pump etc.
Electron cavity: renovation, perhaps including new plungers, if they are ready in time.
A more powerful kicker supply will be made to enable some experiments aimed at running a ring (ASTRID II ? ) with negative momentum compaction factor, which makes sextupoles superfluous as a means to avoid the head-tail instability.

The positron beamline will be mounted starting this week.

The Microtron needs a few changes: The new HV supply will be connected and tested. It is hoped, that this can increase the stability of the machine. Besides, the dipole coils have to be cleaned.

A new control system net has been installed by FS, and TW stresses, that ONLY control system PC's are to be connected to his net. Others should be connected to the standard net.

Our NT server is having some problems with available licenses, and TW asks that you log off the net when you do not use it. Do not map drives etc when they are not needed. There are steps being taken to improve the situation, but for the time being, do not tie up resources you do not use. If you experience problems printing etc, the computer people are unable to do anything - it is simply because too many users are using the system. All you can do is wait!
