Y-chamber Laser Window - Evaluating the best window to minimize birefringence under stress

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 of reliable design to operate at 200 kV with shorter throw

WF Wien Filters (200 kV upgrade) - Upgraded Wien filters with 20 A magnetic coils and >18 kV electrodes to rotate spin of 200 keV electrons

QW Wien quadrupoles (200 kV upgrade) - New quads designed for 200 keV energy, w/ improved magnetic field quality

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

HD steering coils - New steering coils for the A1/A2 aperture cubes, improved design and for 200 keV energy

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
