Abstract

The Orion facility is used mainly for studying high energy density physics. It has ten “long” pulse UV laser beams, two “short” pulse Petawatt beams and ancillary beams for probing of the experimental conditions. Occasionally experimental teams are requested to perform dedicated shots of a given configuration to obtain information on laser target fragments and their effects on surfaces within the target chamber. After these test shots witness plate surfaces were inspected by optical microscopy so that palliative measures could be taken or modifications to the experiment undertaken to minimize any deleterious effects on laser optics or diagnostic instrumentation.
