Cleaning the 10-inch Ceramic Break
Equipment/Beam Line: 

2015 Sept ~ 10 - 30

Due to unwanted sputtering process of gold and copper on 10-inch ceramic break, conditioning the BNMR HV cage faces difficulty. Ceramic piece was removed and cleaned.

Cleaning of the Al2O3 inner surface was done with diamond paper abrasive, wetted initially with water, then ethanol in final stages. When completed the inner surface was a visibly lighter and more uniform shade. About 6 hours of sanding was done. Not all surface defects were removable.
