H/D separation project

[Alexander Vasilyev <vassilie@mail.pnpi.spb.ru>]

Dear Claude,

Thanks for your mail.
The list of the dates will be sent to you by Marat today or tomorrow.

We are almost ready to pack our "separator"! During this week
EVERYTHING will be ready.

We do not have up to now COMMON opinion with Alexeev's team about
algorithm. Perhaps we will need few additional days for the tests with
separator itself. Can you find for temporary using additional pressure
sensor on 10 bar? We are going to measure (and perhaps stabilize)
pressure at the top of the separator.

I am strongly against using of the "natal" hydrogen for the tests.
I can assume that for the tests we will need additionally (1 m^3 -
basic value for the filling of CHUPS plus TPC) about 500-700 l of
protium. So, we have to have before separation (19.03 ... 23.03) about
1.7 m^3 of protium. Pressure of this protium does not meter.

So, I am positive, today we have as  separate pieces more or less all
for separation. I do not know now the situation with differential
pressure sensors (ordered by Peter).
Shapkin and Co. have a good progress with analyses. So, I understand
how to stat separation... (More info about Shapkin's success will be
later)


With best regards   Sasha.





CP> Please, inform Anita as soon as possible of your travel plans (arrival, 
CP> length
CP> of stay at PSI). We made preliminary guest house reservations from
CP> March-1 to June-30.

CP> Here are a few news:
CP> - the cold head is due to arrive next Monday
CP> - our beam time (April-6 to June-19) is approved

CP> I will be absent in Japan from Feb-23 to March-1. So you will not see
CP> me before March 2nd, but Malte and Anita are around, if you need help.

CP> I'm looking foreward to see you soon!
