The final aim of the work package is to deliver disc targets to the interaction area and suspend them without physical means of attachment, because such supports are known to perturb the ion-beam production mechanism and generate unnecessary debris. Recently established target technology (using techniques common in the semi-conductor industry) will be developed to cheaply fabricate targets of different shapes, thickness and composition. In particular, by exploiting the expertise available within the consortium (including advanced modelling and simulation), we envisage a coordinated approach which will allow optimal target delivery for a high repetition particle source. For ion and proton sources, a crucial point will be the large volume production of limited mass targets. We will develop a target injection system, resident within the interaction chamber, based on electrostatic delivery techniques and additionally the optical levitation concept for fine control, positioning and orientation of ultra-thin disk targets, enabling target systems operating at greater than 1 Hz.

As listed in the left hand column, the multi-disciplinary group is constituted by experts from several organisations in the UK, such as Rutherford Appleton laboratory, University of Southhampton, and Imperial college London, and the group will be accessing highly sophisticated, state-of-the-art facilitites located at Rutherford Appleton Laboratory.
