The beam monitor data exceeded this count limit several times and posed major problems in normalising the data ... This was used in the data save routines; the first twelve or so values were read from electronics (beam monitor, time etc.) and the ...

Simulated experiment Beam from cold guide H15 arrives at vertically focussing graphite monochromators. The monochromatic beam passes through a Be filter and arrives at the supermirror bender polariser

Coulter and collaborators [1] first showed that it was possible to polarise a polychromatic neutron beam by simple transmission/absorption through a polarised helium-3 filter. At the same time, Francis Tasset
