Query: Using Thin Film Targets for Muonic Atoms and Muon Catalyzed Fusion
  Studies   Studies of muonic atoms and muon catalyzed fusion have been conventionally
done in a bulk target of gas, liquid or solid hydrogen isotopes. The use of
thin film targets developed at TRIUMF have notable advantages in tackling some
of the most important questions in the field, which could be further exploited
at future high intensity muon sources. We review the technique of the thin film
method with emphasis on recent results and a future proposal.
