MICE target issues during run 2nd-5th August 2013

On 30th July, prior to MICE running, HN observed some unexpected numbers being read back on the Target Drive panel, which were traced back to faulty cards in the Control Crate in the Target Vac-Rack. This crate provides the interface to the target drive and also to the target frame stepper controller. An ADC and a carrier card within the crate was replaced resolving the problem. The ISIS Gate valve was closed during the replacement as a precaution.
