Major Beamline Components

DR dipole (15 deg) - New 15 deg air core bend dipole replaces pre-existing DS dipole

FX beamline and FY chopper solenoids - New double-coil sw/cw capable solenoids with 38 mm (FX) and 46 mm (FY) ID

PSS Kicker (upgraded for 200 kV upgrade) - New PSS kicker has been designed to operate at higher momentum and with more reliable design

WF Wien Filters (200 kV upgrade) - Wien filters are upgraded with new coils (20 A) and new high voltage (+/- 18 kV) for operation at 200 keV

QW Wien quadrupoles (200 kV upgrade) - New quadrouple are designed for higher 200 keV energy, but also of improved magnetic design w/ minimized dipole component

Chopping System (200 kV upgrade) - Choppers get higher power amplifiers, maybe a new chopping chamber

Pre-buncher cavity (200 kV upgrade) - Existing stainless steel pre-buncher replaced by copper cavity for higher power.

NEG coated 2.5 inch OD BPM's - Replacing (2) existing with (3) new BPM's, provide (x,x',y,y') from gun, help tuning

A1/A2 Aperture Steering Cubes - Reinvented A1/A2 apertures define beam size and PSS kicker destination, include upgraded HD steering coils

Injector upgrade vacuum improvements - Improvements in the vacuum design, use of getter and ion pumps

SRF Booster
