[A1n_d2n] 'Run Group' Elastic Polarized 3He proposal to run w/ d2n 1-pass period

[Brad Sawatzky]

Some of the 1-pass kinematic data explicitly overlaps with our A1/d2
needs, but some time will need to be allocated to the Q2 scan for the
proposed measurement.

We will need to make an appropriate plan for the 1-pass run period in
Jan/Feb 2020, but the request is modest enough that I would not
anticipate a problem.  It'll be a topic of discussion for our upcoming
A1n/d2n collaboration meeting.

The SHMS momentum bite is large enough that we could probably just set
it to a nominal p0 in the range 1.9--2 GeV/c and it'll cover elastics
over the angular range of interest and periods in Table II.
