Re: List of the components - visits to PSI
Dear Peter, dear Alexei and friends,
thanks for the shopping list for CHUPS. It corresponds to what
we already discussed the day before your departure. I will try
to make sure that all things are at hand when we resume tests
in September.
Conc. the Membrane pump, I can agree with the proposal that
it shall be purchased by the PSI vacuum group and we get
reimbursed from Gatchina.
********************
Here is a general comment conc. visits to PSI next fall:
We have some new rules about procedures and what documents
need to be presented, applying to all visitors which plan
to stay in Switzerland for more than 3 weeks. I will
foreward the new instructions as soon as I get it from my
secretary.
The duration of obtaining multiple entry visas is about
6 weeks. Therefore it is rather urgent to define our
visitors program if some visits to PSI shall be done in
September. (Be aware of the holiday season!)
Next week (Monday, July 18 ff) Peter Kammel will be at PSI.
This might perhaps be a good chance to discuss the visitors
program for mucap run 9.
I hope for a successful mucap research program next fall!
With best regards, yours
Claude
