Progress update

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.

 

 

 

Setup allignment

To help us align the instrument we have recently purchased an optical level (Leica DNA03). We decided to design the support ourselves so that we could optimize the stability and handling of the level.

News

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.

Cooling water: new connections

Progress

The polariser and collimator tubes are mounted on the new support. There were some issues but overall the transfer went flawless. The cable ducts will be mounted soon. When the cables are reconnected and the neutron guides replaced we can start alignment.

 

 

Small Angle Scattering school in Delft

We organised a small angle scattering school on 28-29 June 2012 at the Reactor Insitute Delft in collaboration with Wim Bras from the beam line DUBBLE at the ESRF.  Some 40 students from the Netherlands and Belgium came to learn from 11 teachers different aspects of theory, techniques and applications of X-ray and neutron small-angle scattering.  You can find the programme at http://www.rrr.tudelft.nl/sasschool.
