Sanja checked that increasing the
length of the shielding wall built in January 2010 might
be useful to provide a better shielding to the Linac 3
area. A check of the feasible increase will be made
(Action: S. Mataguez, J.-M. Lacroix).
-
The shielding blocks will be
installed on a simple table to avoid conflicts with the
bus bars. The design of such a table should be started (Action:
J.-M. Lacroix).
-
The energy deposition in the vacuum
chamber of MMU15 should be considered as input to decide
whether cooling is needed (Action: MG to contact
D. Bodart).
-
The proposed cooling system for the
dummy septum blade should be verified to be really
radiation hard (Action: ABT).
-
The option of having large size quick
connections for the flanges should be checked as this
would minimise radiation given during interventions (Action:
ABT).
-
The space required for RF by-pass
should be checked (Action: ABT).
-
It is agreed that the two motors
moving the dummy septum blade will be independent to
allow for position and angle tuning.
-
The optimisation of the thickness of
the upstream and downstream shielding walls should be
studied. In principle the tank length could be around
450 mm, i.e., 150 mm less that what was assumed in
earlier simulations. The available 150 mm should be
considered to be available either to increase the
thickness of the downstream shielding wall, or to add an
upstream shielding wall (currently not included at all),
or to provide some play to ease the activities in case
of need (e.g., connecting/disconnecting the flanges) (Action:
GS-SE).
-
Simulations with the current
simplified set-up, but with variable angle of the septum
blade should be performed to establish how to align the
dummy septum blade during operation and to find the best
location of a monitor to be used for optimisation of the
running conditions (Action: GS-SE).
-
Details for the tracking of particles
have been discussed and a set of input file will be
prepared (Action: GS-SE and ABP).
