Abstract
The UK programme of high power target developments
for a Neutrino Factory is centred on the study of high-Z
materials (tungsten, tantalum). A description of lifetime
shock tests on candidate materials is given as part of the research into a solid target solution. A fast high current pulse is applied to a thin wire of the sample material and the lifetime measured from the number of pulses before failure. These measurements are made at temperatures up to 2000 K. The stress on the wire is calculated using the LS-DYNA code and compared to the stress expected in the real Neutrino Factory target. It has been found that tantalum is too weak at these temperatures but a tungsten wire has reached over 26 million pulses (equivalent to more than ten years of operation at the Neutrino Factory). Measurements of the surface velocity of the wire using a single point Laser Doppler Vibrometer are in progress, which, combined with LS-DYNA modelling, will allow the evaluation of the constitutive
equations of the material. An account is given of
the optimisation of secondary pion production and capture in a Neutrino Factory and of the latest solid target engineering ideas.
