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 \({\approx}6{\times}\) at \(\lambda=1.8\) Å, and improvements on discriminating electrical noise, allowing MARI t...

Zusammenfassung:	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.
