There are several methods for measuring transverse emittance. The emittance is calculated from the phase space distribution of the beam measured by Allison scanner. Quadrupole scan with wire scanner or multi wire scanner for RAON injector were also performed to compare with these data. RAON injector consists of ECR-IS, LEBT, RFQ, MEBT. Various diagnostic devices such as 8 Wire Scanners and 1 Allison Scanner were installed in beam transport line. Each diagnostic device was driven by PLC and the current was measured with microTCA-based DAQ system. EPICS was used to control the diagnostic system, and each device was driven and measured according to the sequencer module. In this paper, the measurement result of each diagnostic device and result of the emittance measurement on Ar-40 beam are presented. PB - JACoW Publishing CP - Geneva, Switzerland ER -
