Dear Alexei,

Thanks for your summary. I talked with Claude today and could call
you at a suitable time tomorrow. Within 5-7 PM your time would be fine
with me. Please suggest a time.

Ad 1. We managed to accelerate the ePC2 ring production at the company by
2 weeks. So Andreev and Fetisov should come already around April 24. 

We should also discuss 
 the Be window plans
 potential Kentucky contributions to the gas system tomorrow. 
 A colleague mentioned to me that one could use a zeolite trap as an oil
 free forepump, I don't know how realistic that is.

With best regards

Peter
