1. Polarized 3He target installation
A sequential breakdown of installation during a summer down.
Revised
Itemized schedule will be made after all parts are accounted for.
Installation schedule is based on:
All assumed existing parts are recovered and usable
All Platforms are fabricated
2 days of magnet/target preassembly in workshop
Minimum of 4 Technicians available at all times
Participation of experimenters as per schedule
Beam schedule remains as is
10/17/2019
