Hi Chris, 

We do not need it at the moment (and probably not until after the 4th of July) for target operations in Hall A or C.

Hi Chris 
I know Halls B and C are using 4 atm helium. 

Hall B can go for the 3 days with out 4atm helium. 
Will we be able to float on recovery? 

Steve 
Will you want to go on and off or just 
Float like B?
