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".
