We have mounted a new nose on the exit of the neutronguide that will be used for SANS. The new nose will protrude into the Velocity Selector shielding so that no extra shielding is needed. We have also incorporated an internal BN-diaphragm that will reduce the beamsize to 30x40mm.
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.
Movements in the blue tube have been tested to see if they work properly. We need to change some connections so it seemed wise to check the current situation before that. Everything works fine. We have also connected the Velocity Selector (VS). It works, but more tests are necessary.
At the moment we are trying to solve a problem with the detector translation stage. It seems to skip some of the built in microswitches and therefore changes its current position along the way. On the next valid switchposition the current position is corrected and the cycle restarts.
The design of the support for the collimator tube is finished by Ruud van Tol.
Here you can see this design and an overview of the complete line up.
The detector on its way to the new support.
The detector of our SANS instrument is a He-3 gas-filled detector.
The detector tube is now mounted at the right heigth by extra feet. The electronics are installed on top of the tube.
