ISA meeting

Week 32, August 8, 2000.

Status of the ring: There has been up to 130 mA of stored beam all of last week, including the weekend. Lifetime has been gradually improving. Yesterday, during the Monday machine time, we modified the tune at injection energy, and managed to store about 160 mA, which was repeated this morning. The microtron is running very well, and injections have been extremely stable. Last week we looked at the new white noise vertical excitation setup, but it was no improvement over the old system in terms of stability and lifetime, so we went back to the old system. Tomorrow (Wednesday) we will use the new system during the day in order to get feedback from the users on its performance.

Monochromators: Our Chinese guests are still running on the SGM I for the remainder of this week together with ZL. They report to having obtained all the results they had planned for, and are now expanding the experiment schedule. They will also use the SX-700 for some measurements. They are investigating Erbium on Silicon, a system used in IR photoelectric devices for fibre transmission systems.
There has been light through the X-ray microscope. A pinhole has to be changed, but the system will be ready for measurements next week, when Eric Chantler will visit us once again.
The UV1 is being set up, first with some absorption experiments for calibration, and next with some known CD samples.
The SGM II is running experiments for DF et al.

S.A.L.A. - "Synchrotrons, Accelerators and Laboratory Astrophysics" will be held at IFA during August 30 - September 1. See info on http://www.isa.au.dk/sala/index.html.
