Observation cameraCan be standard CCD or
Vidicon tube camera
OUTIN
Insertion deviceHolding an
in-vacuum radiator
LightsMainly used for system calibration and beam
steering
CTRL ROOM
- Beam observation- Beam steering- Emittance measurements
RadiatorCan be scintillating
(Al2O3, ZrO2 etc…) or reflecting material (C, Ti, etc…) depending on the application and type of
beam

BTVs @ ELENABTV general description / principle
Relocation of DE.MTV7045
Location of new BTVsBetween Speta and Kicher
BTV x ELENA IIC 2014_09_18 S.Burger, R.Sautier, N.Sharmazanashvili BE/BI
BTVs @ ELENABTV general specs
- Need: - 1 BTV for beam injection measurement - 1 BTV for circulation beam measurement
- Location between injection septum and kicker- Limited space for 2 systems (!) -> choice turned into a common vessel for the 2
devices (See Roland’s section)
- Default position of screen:- OUT for BTV on injection line- IN for BTV in circulating beam -> EIS system (means an action is needed to take the screen OUT)
- Try to have a common design of screen insertion device despite the difference in functionality. Development based on a pneumatic magnetic coupling device
(See Nikoloz’s section)

BTVs @ ELENAControl and acquisition chain
VME based card• CTRL of the camera• CTRL of the lights• CTRL of the filter wheel (not foreseen for ELENA)• CTRL of the movement• Digitalization (400x300 pixels)• Interlock interface if needed
Camera• Analogue B/W to match the standard CERN BTV system• S/N > 50dB• Minimum illumination 0.0002lx (F1.4)
Rack / Crate• No need for new hardware since space available for 2 BTV cards in cfv-193-btv2 (AD extraction line + BASE)

Connection structure of Drive thimble with
pneumatic Rod
Note : Connection structure of Drive Thimble also serves as a Anti – Rotation tool and assures linear movement of inner Vacuum Shaft !
Device description:• Provides linear motion of the
vacuum shaft.• Vacuum shaft and Drive Thimble are
magnetically coupled.• Both the driver and the follower
consist of arrays of equal numbers of permanent magnets with poles.
• Removes the need for edge-welded bellows ‘stacks’, incorporated within traditional ‘push/pull’ designs - their elimination maximises vacuum integrity!
• Unlike a bellows-sealed device, the MPPL is not subject to the thrust due to vacuum, resulting in smooth free-moving operation.
Assembly components:• Inner Vacuum shaft• Drive Thimble• Flange DN100 – 316LN• End Cap • Position Locking screw
