Oscillation of emittance and Twiss parameters in the negative ion (H⁻) beam is measured by application of a double-slit emittance monitor located at the RFQ entrance. The systematic error was valued in emittance measurement of CSNS RF ion source. This article mainly discussed the measurement accuracy and reliability of the double-slit emittance meter. Therefore it is shown that the working principle, mechanical disign, electronics and the application in CSNS RF ion source were introduced. PB - JACoW Publishing CP - Geneva, Switzerland ER -
