Test method for position of accelerate grid of megawatt level high current ion source
Background:Accelerate grid for producing several tens of MW ion beams is a critical component of the megawatt level high current ion source for the high power neutral beam injection.Purpose:To measure and analyze the position of accelerate grid.Methods:Taking the exit grid module of EAST-NBI high current ion source as the measurement object
the observation point coordinates of accelerate grid rail’s actual axis are obtained by using 3 quadrantel points sampling method and the point coordinates are analyzed by using MATLAB optimal function. Results:The position error that tallies with minimum zone and the distribution regularities of accelerate grid rails are obtained.Conclusions:This method has simple and stable course of evaluating
can realize automatic measurement and provide the basis for improving and finalizing the grid module’s processing technic.
