ISA meeting

Week 18, April 29, 1997.


Status of the ring: The first electron run this year ended Sunday night. The machine has been performing very well up to the end.
In conclusion this run has been very successful with a very good performance giving 180-200 mA of accelerated beam at each injection and with a lifetime in excess of 15 hours. And this with the new undulator chamber and with the undulator closed to 25 mm gap. Also the successful installation of the undulator beamline including monochromator and David Fields experiment is worth mentioning.

The next ion run will start on Monday 12-05, and the hardware changes in the ring is being made now. This includes change of cavity, change of vacuum chamber in section 2, replacement of lens in flourescence port in section 1, replacement of bunched beam current transformer, and installation of cleaned injection beamline.
Our vacuum system is presently being connected to the new control system, and this means that the bake-outs late this week and next week also will be made on the new NT control system.

Additions/changes to hardware needed before the next electron run starting in week 32 should be collected next week. So please prepare a list of such jobs. Known things are modifications to undulator beamline, electron-cavity, modified kicker?, mirrors on SGM, new HV for microtron.

Most ISA-employee's will be represented in IFA's "sikkerhedsorganisation" by a special "sikkerhedsgruppe" called "ISA Drift & udvikling". Jens Vestergaard has been elected "Sikkerhedsrep." and Søren Pape Møller as "Arbejdslederep.". Niels Hertel is still responsible for radiation safety at ISA. Furthermore EU and RL belongs to the "sikkerhedsgruppe Bygning & kontor" whereas US, GC and PL belongs to "Mekanisk værksted".
