[Dsg-mvt] MVT with premix in hall B

[mdefurne]

Hi all,

I just would like to comment on Stephan's e-mail. 10 days is an 
optimistic evaluation, especially if we run both FMT _*and*_ BMT 
micromegas. Unfortunately we cannot really be thrifty on the gas 
consumption. Indeed we tried to save some gas this summer and the 
micromegas does not work properly if you are not running with nominal 
gas flow.

Thank you,

Maxime
