We have been preparing to move the blue tube to it’s final position. The Velocity Selector is aligned, as is the neutron guide between Velocity Selector and Blue Tube. Vacuum is OK in both systems. We still have to build some shielding around them and the Velocity Selector still has to be fixed to the floor.
In July we’ve had some help from Oliver Frank adjusting the detector translation mechanism. It was a very stimulating visit and Oliver provided a lot of information on what is under the SANS-hood.
To access the blue tubes the tube sections can be moved along the axis of the setup. Due to space issues it will be very difficult to disconnect the cooling water when SANS is at its final position. We have therefore changed the cooling water in- and outlets so that spiralled tubing can be used.
The new parts for the blue collimator tube are finally here: ITEM tables, mounting material and steel beams.
