Who’s doing what? • CPA mechanical • HV cup/arm - ANL providing all assembly except… - Davis - W&M making channels nuts, z • HV supply/feed through brackets, profiles, and connector tabs - KSU/UCLA - CERN providing resistive cathode sheet and frame covers • Resistor divider chain • APA mechanical - LSU (boards, nuts, bolts) - ANL making frame, sheets, and edge weldments, mounting feet for both - KSU (I cannot recall this morning) APAs - Yale (HV test) • FC mechanical • CPA/APA electrical connection - W&M providing FC and base - BNL providing profiles, end caps - ??? (not Wisc like in PD, right?) - SBU providing G10 pins for frames • Local electrical approval, PORC, • Top/bottom ground planes ORC… - CERN - FNAL 4 7/28/16 HV test mechanical

Assembly steps APA bolts to I beam of lower HV wall 5 7/28/16 HV test mechanical

Assembly steps • Add the top HV cages • Bolt to APAs & CPA • Then add the top ground plane panels • Comes in 6 parts 6 7/28/16 HV test mechanical

Assembly steps • End wall HV bolts to tabs in the APA frames 7 7/28/16 HV test mechanical

W&M Update • Still working to get a vendor for cutting Shop work the FRP parts; getting help from • Completed profile nuts Thomas and Vic • Completed connector plates for APA • Small parts to be ordered this week • Working in Z-clips • High bay prep Clean room prep - Next week cleaning and reconfigure space (students arrive Wednesday) • Got small parts heated ultrasounds cleaner - Epoxy coating for FRP parts, staging, shipping crate assembly, large • Take over clean room from a JLAB cleaning bathtub, Cherenkov (GRINCH) project next week • Clean up following week and arrange work space (students arrive Wed) • 20x20 foot^2 with an 8x8 cut out in one corner • Inside a 36x24ft^2 lab, which we own for project 8 7/28/16 HV test mechanical
