A new dynamic method for thermomechanical characterization of candidate target materials (tungsten, tantalum and molybdenum) has been developed
as part of the program advancing high power targets for the UK Neutrino Factory. The materials used in the target systems of next generation high power particle accelerators are frequently exposed to a combination of high stresses, high strain rates and very high temperatures. To estimate the lifetime of target and target system components in this environment, the candidate materials have to be tested under extreme conditions.

A thin wire made from the candidate material was heated and stressed by a fast high current pulse generated by a power supply for the ISIS synchrotron (Rutherford Appleton Laboratory) kicker magnets.
