Through developing a restoration device,we can resume the defective ion pump without damaging the vacuum system,within a shorter period.The ion pump restorer was designed under the following ideas.With the aid of a bracket the ion pump body was firstly rapped under the vacuum detecting element monitoring,so that the impurity between negative pole and anode,which could create short-circuits,was shaken off,Meanwhile a 6 kilovolt DC voltages between negative pole and anode was applied to discharges the impurity through Pan eliminates,that resume the ion pump to work.In the experiments of 5 times service,four incidents of the ion pump break-down were solved by restorer and the accelerator could reach its standard operating vacuum degree -5.8 Torr.The success rate of 80% indicated the restorer was effective pratically.
