Upgrade of the MARI spectrometer at ISIS

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 approximate to 6x at lambda = 1.8 angstrom, and improvements on discriminating electrical noise, allowing MARI to continue to deliver a high quality science program well into its fourth decade of life.
