[b1_ana] slides

[Long, Elena]

Good evening,

I haven't finished up all the changes from Friday's discussion, but I did include Dustin's slides in the same format as the rest of the talk, and began updates from Friday. Current versions can be found at http://nuclear.unh.edu/~elong/analysis_files/2013-06-16/

Take care,
Ellie

The statistic gets worse as (20/12)^2, or (20/15)^2, so I think the smallest
Pzz we can mention is 15% (Pz ~ 44%).

i forgot to share the tech notes on ND3 polarization that Don sent me last
week, although I think they are the same ones we used for the proposal. The
field dependence is on p. 6 of the note on the research run in B28.

My bet is that at constant microwave power, ND3 Pz will be definitely higher
at 6.5 T than at 5 T. And remember that Pzz increases much faster than Pz,
above Pz = 45%, so a 10% Pz increase results in more than 20% Pzz increase.
So, even if Pz  increased by only 10% from 5 to 6.5 T, we would gain a lot.

Also there is FM modulation of the microwaves, which was used at SLAC, and I
think at JLab too, which, if I recall correctly, it at least slows down the
decay with dose.

Cheers,

Oscar
