Design and performance of a non-destructive beam-profile monitor utilizing charge-division method at HIMAC

A non-destructive beam-profile monitor employing micro-channel plates and a resistive anode that can be applied to a detector has been developed. The monitor works by a method of charge division to determine the spatial position for an event of residual gas ions on a detector. Two monitor units for measuring the transverse horizontal and vertical density distributions of a circulating beam were installed in the HIMAC synchrotron. The monitor has been used for an electron-cooling experiment with a spatial resolution of less than ±0.38 mm, as well as for studies of beam dynamics under routine operation in the synchrotron. The design and reliability of the monitor as well as some results of the performance are described.
