Polarized 3He target installation A sequential breakdown of installation during a summer down. Revised 07-16-2019 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

Polarized 3He Target Installation summary Assumptions: Installation starts Tuesday August-06, 2019 – Nov. 30, 2019 (*) Manpower: 4 Mechanical Techs, 1 Supervisor, plus Hall A Tech support when needed Modest support from: Spectrometer support group (Segal, et al + M. Taylor) Electrical / Cable / Fiber / Power installation (Joe B.) Survey and Alignment Group has been made aware (*)Installation schedule is conservative and based on one shift per day (see next slide) Existing equipment and parts will be grouped in 2018 Some cable and fiber installation will start in 2018 (Joe B.) 10/17/2019
