Query: US Muon Workshop 2021: A road map for a future Muon Facility   The workshop titled "US Muon Workshop 2021: A road map for a future Muon
Facility" was held virtually on February 1-2, 2021. The workshop aimed to bring
together world experts in muon spectroscopy ($\mu$SR) and other techniques
along with interested stakeholders to evaluate the scientific need to construct
a new $\mu$SR facility in the United States (US). The more than 200
participants highlighted several key scientific areas for $\mu$SR research,
including quantum materials, hydrogen chemistry, and battery materials, and how
each area could benefit from a new, high flux pulsed muon source. Experts also
discussed aspects of the $\mu$SR technique, such as low-energy $mu$SR, novel
software developments, and beam and detector technologies that could enable
revolutionary advances in $\mu$SR at a next-generation facility. The workshop
concluded with discussion of a concept being developed for a new $\mu$SR
facility at the Spallation Neutron Source (SNS) of Oak Ridge National
Laboratory (ORNL). That novel design concept was first envisioned by many of
the same $\mu$SR experts at a workshop held previously at ORNL in 2016. The
participants expressed that the current design had the potential to be a
world-leading $\mu$SR facility, and strongly encouraged the principal
investigators to continue their work in order to refine the concept and
determine instrument parameters that would enable new scientific opportunities.
