Upgrade of the MARI spectrometer at ISIS

Abstract

The MARI direct geometry time-of-flight neutron spectrometer at ISIS has been upgraded with an $m=3$ supermirror guide and new detector electronics. This has resulted in a flux gain of $\approx 6\times$ at $\lambda =1.8$ Å, and improvements on discriminating electrical noise, allowing MARI to continue to deliver a high quality science program well into its fourth decade of life.
