BTVs @ ELENA BTV 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) BTV x ELENA IIC 2014_09_18 S.Burger, R.Sautier, N.Sharmazanashvili BE/BI

Connection structure of Drive thimble with pneumatic Rod BTVs @ ELENA MPPL 100 – 100 – P (1) Connection structure of Drive thimble with pneumatic Rod 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. Note : Connection structure of Drive Thimble also serves as a Anti – Rotation tool and assures linear movement of inner Vacuum Shaft !
