IN8 with 15T

158OXHV26 (15T)

Stray Magnetic Field and Siting Issues on IN8

We present below the magnetic forces measured on IN8 with the 15T symmetric split-pair coil magnet 158OXHV26. The measurements have been performed for a few positions of A2 and each time for the whole range accessible with A4. The graphs below are extracted from the data.

To summarize, the acceptable maximum field is 11 T for a distance of 450 mm between the monochromator shielding and the edge of the cryomagnet (distance measured on the incident beam axis).
