Recent and future developments on TOSCA at ISIS

TOSCA is a high-resolution neutron spectrometer at the ISIS Pulsed Neutron and
\nMuon Source. The instrument is optimised for broadband vibrational spectroscopy in the
\n0 – 4000 cm-1 region and it has been operational since 2000. This paper describes how the
\ninstrument has been progressively upgraded in the intervening years to enable new science.
\nFuture upgrades are outlined.
