Need
: 1 BTV for beam injection measurement 1 BTV for circulation beam measurementLocation between injection septum and kickerLimited space for 2 systems (!) -> choice turned into a common vessel for the 2 devices Default position of screen:OUT for BTV on injection lineIN 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.

Slide10Device description
P
rovides 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.BTVs @ ELENAMPPL 100 – 100 – P
