1. Early running planning process
Hall C User community discussions
Several Hall C User meetings
SHMS-HMS Users Group board meetings
Early running criteria/goals
1. Do mix of short experiments with modest requirements that provide calibration/performance information for subsequent experiments.
2. Do experiments of “young” spokespeople and contributors to upgrade.
3. Do A/A- experiments
4. Do some SIDIS early to support lab SIDIS effort
5. Utilize Hall C L/T capability
6. Utilize polarized beam (execise Compton/Moller upgrades)

2. Draft early running plan – Year 1
2015: ~25 PAC days – Commissioning “Experiment”
9 days of E search for color transparency (B+)
A(e,e’p) only – “easy” coincidence measurement
E F2p,d structure functions at large x (B+)
Momentum scans help understand acceptance
2 days E EMC Effect (A-)
Integrate light nuclei with F2 run,
Point target helps acceptance studies.
3 days of E d(e,e’p) (B+)
If time available
Push to lower cross sections
F2 and C12 scans good for acceptance studies

3. Draft early running plan – Years 2-3
2016: PAC days
E (A-) Pt dependence of basic SIDIS cross sections
Push particle ID capabilities of SHMS
E (A-) Precise +- ratios in SIDIS – CSV
Detector efficiencies
E (B+) L/T separated (e,eK+) factorization test
Easiest L/T separation
92 PAC days total – collaborations forming joint run plan and prioritizing
2017:
E (A-) g2n measurements at fixed Q2
First polarized 3He target experiment in Hall C
E (A) high x A1n

4. Polarized 3He target comments
Year 1 could slip beyond 2015 after 12 GeV re-baselining. But, as most Hall C 12 GeV funds have been committed, Hall C slipage “could” be minimal. Till now, has been assumed that target will run in Hall A first. Hall C OK with first 12 GeV use in Hall C if: Collaborations of approved 3He experiments supports Management supports and funding adequate Would like healthy time separation between 3He target use in different halls.
