Re: D2 measurements

[Claude Petitjean <claude.petitjean@psi.ch>]

Dear Sasha,

unfortunately I was sick one week, that's why I answer only today to 
your proposal of residual D2
concentration measurement. About additional equipment which you need, I 
see no problem conc.
a precise pressure sensor and some additional valves. They can be 
organized with moderate
money within a few weeks.

However, your inquiry to order 4 more 10 liter pressure bottles is 
difficult because I hardly
can get them produced by our local people. This means huge time delays 
and large costs.
Perhaps we can use the dummy TPC as additional 30 liter volume? What is 
the maximum
pressure you need for the D2 measurements?

As you may have noticed in my last mail, the period from mid April to 
mid June 2006 is most
suitable for me, since I could support your group 100%.

With best regards

Claude
