Description
The CSNS will refurbish the ion source, RFQ and MEBT sections this year, among which a new compact emittance meter at the MEBT is required. This emittance meter will be intergated with beam scraptor and wire scanner owing to the compact design of the CSNS MEBT section. This emittance meter consists slit in blades made of tungsten, and four SEM wires to visualize the beamlet profile. In this paper, we report the optimization of the slit structure, beamlet drift distance and wire diameters in the presence of realistic conditions. Moreover, the selection of material and accuracy of the transverse phase-space distribution measurement are also outlined.
