| ==Cleaning/polishing Targets and Substrate Holders== |
| |
| The process we use for cleaning targets/substrate holders includes a series of increasing grit sand paper. The grit sizes range from 200 to 2000 and depending on the density of the material we may start at a smaller or larger grit. For example a soft ceramic target will most likely require you to start with a higher grit (say 800 or 1000) while polishing the substrate holders may require a much lower grit (say 200 or 400) to remove as much of the deposited material as possible. One thing to keep in mind when polishing targets/substrate holders is that the type of material you are polishing may be toxic. A list of toxic metals which need to be disposed of through EH&S is posted on the fume hood and can also be found {{:pld:hazardous_heavy_metals.docx|here}}. |
