This is what the neutrons will see when they travel through the flight tube. Sections of tapered Boron rubber so neutrons that plan not to participate in the measurement will end up in the small edges of Boron rubber.  

Michel is now winding our biggest guide coils ever that will be used on the first table. The coil is slowly spinning with an strong electrical motor and Michel is running and climbing to feed in the wire.

We have tested the movement and locking system on the magnet. This appears to work better than expected. After this we even changed the gearing ration so it will move a bit faster than in the short movie made by … Continue reading →

  Thanks to a big effort from our student Maurice we just measured the first oscillations that are the signature of LARMOR diffraction. On the photo the 4 RF flippers create a B-field parallel to the crystal plane in the … Continue reading →

We are building a High Resolution Larmor Diffraction instrument in the reactor hall of RID. The key components, the RF flippers are from the FLEX Triple axis instrument. With these flippers the first Larmor diffraction experiments were performed years ago in Berlin! … Continue reading →

Check out the LARMOR twitter from ISIS for more on the first SANS data with the final detector…

The RF flipper is almost ready to be tested. It does look pretty with all the shiny copper but there is quite some development underneath. A RF coil is fixed by epoxy in a 3D printed mold. On top is … Continue reading →

One other box that is ticked. The magnetic field regulation does work perfectly. We can set and control the magnetic field of the magnet from -100 mT to +100 mT with an accuracy of 5µT. A set-point is reached in … Continue reading →

It is not the best picture, however we are very happy that the first magnet set arrived. The picture shows one half of this set that is just installed on the small rotation stage that sits on a translation stage … Continue reading →
