The FECMAIN program for the beam diagnostics is
definitively showing failures quite often. It fails every couple of hours. Ivan
Deloose has been asked to fix this problem when he is
back from vacation on 18th of July.
v
The order of the NI electronic parts and
software which have to be used as the basis of the new control system has been
sent (Twincat programs and Profibus master PC interface card).
v
Michael O’neil
accepted to look at the broken optical to TTL connection box. It is already
repaired; however Michael wants to change some components to make it more
reliable.
v
Lisa the student of Peter Butler should join
Romain to do the last tests of rotating wall cooling
with REXTRAP as soon as this box is ready.
v
The Li ion source sample should be put in place
at the end of the week possibly by Lisa and Anne, the other summer student of
Peter.
v
The LMU emittance
meter has been removed and given to Ivan. At its place on the WITCH beam line
the silicone detector has been installed. Tests should start when Fredrik is
back with Lisa and possibly Anne.
v
The outer vacuum chamber (OVC) is still pumped.
Now that the temperature is becoming higher (100K measured by means of the Allan
Bradley resistors) the outgasing rate is quite big.
The pressure inside the OVC this morning was 3 x10-2 mbar before the
daily pumping.
v
Nicolas David has finished to
install the Spellman 6kV supply in the EBIS cage. Electrical installation
inside the racks should be improved. From what he observed there is no straight
way to switch off completely the racks one by one.
v
Mats got from the RF group that the
commissioning of the last amplifier was not so easy. More details from Thomas in
the near future.
v
Welcome to Lisa Willenegger and Anne Holm who will work for two months on
REX-ISOLDE and MINIBALL experiments.
