ISA meeting


Week 4, Jan. 21, 1997.

Status of the ring: During the past week we have been running negative clusters for Phv and his group. The clusters were Al, Ag and Ni. We used the sputter source, which by the end of the week had been running well for 2 weeks without interruption!

Yesterday we started running Mg+ for JH & Co. They will be running this last week of ion run 2/96.

The present run, ion run 2/96, will end this week. On Monday morning, construction of the new platform for visitors will start. This should finish in week 5. We will then start running electrons in the ring, such that we hopefully have a good beam ready in the beginning of week 7, when experiments are scheduled to start.

This means that the ring hall will be closed in the last half of week 6 and all of week 7, at least for a large part of the time.

During the shutdown, a plain beam pipe will be mounted from just after the cryo pump to the second pair of electrostatic quadrupoles in the injection beamline. This is in order to have the present injection beamline cleaned.

The positron test beamline is active, and positrons have been observed by JM. Because of the location of the beamline (above the microtron) there is a large background, which makes it more difficult to determine the numbers of positrons observed.

JM is working on that, but it will be easier when the real beamline is set up, such that the positrons are transported into the new positron lab.

The new SGM: At a meeting to discuss the new SGM on January 8th , some decisions were made. A memo from that meeting is reproduced on the back of this page.

Tools are often borrowed from the ISA toolboxes in the ring hall. KI says that it is OK to borrow tools, but you MUST put them back as soon as you finish your work. Too much time is wasted by the technical staff looking for tools.

In addition, please keep the ring hall clean and tidy. If you have worked on something down there, clean up when you are done, and make sure everything is back in its proper place.
