Contract Number:

ERBFMGECT950001

Contractual Period:

1 February 1996 to 31 January 1999, 36 months

Objectives of the Project:

The development aims at making ultraslow muon spectroscopy available for studying the structure and dynamics of thin films, surfaces and interfaces using the pulsed muon source at ISIS. The ultraslow muons are produced following moderation in cold inert gas thin films and a principal objective of the project will be to increase the efficiencies of these moderators. The development comprises: a) the design and construction of a UHV vacuum system incorporating a helium cryostat, b) a demonstration of the ability to deposit controlled thicknesses of solid inert gases and c) the design and construction of a beam transport system up to a simple ultraslow muon mSR spectrometer.

Keywords:

Muons, Surfaces, Thin Films

Results and Achievements:

The period 1st February 1996 - 31st January 1997 has been devoted mainly to designing the ultraslow muon apparatus, together with initial assembly and testing of the major components. Initial trials of the moderator and demonstration of ultraslow muon production are scheduled for the DEVA beamline at ISIS in May 1997.
