I am currently investigating the ability of a plasma to attenuate a stream of ion beams. During the
process of generating ultraviolet light by means of hitting a tin (Sn) droplet with a laser, a high energy
tin plasma is created. ASML, the company funding the research, would like to understand how different
parts of their chamber, some filled with gas and some with a hydrogen plasma, will interact with these
high energy tin ions. My work currently includes running experiments on the HARP chamber which
has an ion beam and helicon plasma source as well as modeling different components of the
experiment. One such modeling effort can be seen in the figure which shows a simulation of an ion
beam like one used on the HARP experimental platform.
