“…Beam experiments were performed using ion beams generated by a 18 GHz superconducting ECR ion source at the Korea Institute of Fusion Energy (KFE) in Korea. This ion source is designed to extract a wide range of ion elements from gas to metal, and the maximum output current is optimized especially for the extraction of Ar 16+ [34], [35]. The pepperpot device is installed the downstream of the ion source.…”

A pepper-pot diagnostic device was developed to accurately and robustly retrieve particle distribution in horizontal and vertical phase spaces by single-shot emittance measurements. Two masks that differ in both composition and manufacturing method were fabricated: one made of phosphor bronze by an optical lithography process, and another made of stainless steel (SUS) by laser cutting. Scanning electron microscope measurements of the two masks revealed that the former is superior in terms of regularity and shape of the mask holes and is therefore more suitable to use. A new image-processing algorithm, namely the cluster noise removal method, was developed which improves the resolution of the phase-space distribution measurements over traditional methods. The device was tested in experiments with low-energy argon beams generated by an ECR ion source at KFE. Results show that the diagnostics can robustly and reliably retrieve the four-dimensional phase-space distribution of ion beams with a single-shot measurement.
