ERR Planning
Information stuffs
Silviu's Hall C talk Includes a proposal for a new target system (that may or may not be built). Yes, there's more room for solid targets, but because there's no loop 3 (Meekins already said that's a way to add more targets).
Food for Thought and to help us make decisions
PRIMARY PHYSICS TOPICS:
0) 2 <= A <= 12 - Extract EMC effect and SRCs for nuclei where detailed ab initio calculations can be performed - Examine nuclei with significant cluster structure - Use nuclei which differ by single proton(neutron) to extract contribution of 'smeared' nucleon to F2A
1) 2 <= A <= 96, |n/p-1|<20% [11 nuclei] - A-dependence over maximal range in A with minimal isoscalar correction
2) A ~ 50, 1 <= n/p <= 1.4 [6 nuclei] - Map out variation with n/p with minimal A-dependence
3) 12 <= A <= 232, n/p grows as ln(A) from 1 to 1.6
