ACTUATION SYSTEM
Completely new design never manufactured
Movement
- Two step motors each jaw Jaw tilting
- Stroke: -5 25 mm
- Spring-back: in case of electrical short-cut the jaws must not go in beam direction
Instrumentation
- 3x LVDT each jaw: 2x absolute movement, 1x relative movement (anti-collision)
- 3x switch assemblies each jaw : 2x absolute movement, 1x relative movement (anti-collision)

TANK
Completely new design never manufactured
- Manufacturing process based on Ph.II tank.Electron Beam welded Stainless Steel.
- No cooling system
Fix RF fingers
Flexible RF fingers
NEW DESIGN OF THE EXTREMITIES
To gain longitudinal space, the bellows after and before the collimator will be integrated into the tank transitions.Longitudinal stroke: +5; -15 mm
Radial stroke: ±10 mm

LAY-OUT
Vacuum Equipment
- 2x D-500-5 NEXTorr Pumps(integrated NEG Ion pump)
- 1x VVFMF DN 40 valve for mobile pumping
- 2x VGPB DN35 Penning pressure gauges
- 1x VGRB DN16 Pirani pressure gauge
This lay-out agree with VSC group allows to solve previews integration conflicts
