Mushroom will provide a huge capability boost compared to the comparable existing ISIS instrument (LET), which is frequently oversubscribed.

Mushroom will provide unique information on the dynamics of samples two orders of magnitude smaller than the current state of the art, giving unique input into the functional materials design process much earlier than currently possible. Mushroom will support the materials science requirements of a large range of priority areas: clean growth, hydrogen economy and quantum technologies.
What will Mushroom do?
Mushroom will enable significant acceleration in the materials discovery and utilisation process. For example, the study of barocaloric materials, ideal candidates for environmentally friendly refrigerants in cooling applications from food storage to computing.
Watch Prof Andrew Goodwin from the University of Oxford talk about the applications of Mushroom:
Technical Success Criteria • Maximise the count rate compared to LET as much as feasible but at least x10 for same resolution
• Maximum sample size 1x1 cm (small sample spectrometer but also necessary for prismatic effect)
• Incident energy range 1 -20 meV (like LET)
• Energy resolution (PG002) not worse than 80 μeV (at elastic) as this is quite typical for LET in a common running mode (Ei=3.7meV)
• Q resolution similar to LET for Horace scans (typically ΔQx≈ΔQy≈0.07Å-1at 3meV)
• Incoming beam divergence maximum ±1.5degrees but can be controlled with jaws
• In plane detector coverage 5-170 degrees. Out of plane coverage of ±8 degrees (good for in-plane Horace scans plus for high magnetic fields and pressure cells)
• Velocity selector must not exceed 1m radius
