Under the upgrade program of an azimuthally varying field (AVF) cyclotron in progress at the Research Center for Nuclear Physics (RCNP), an emittance monitor is being developed to improve the beam injection efficiency from ion sources to the AVF cyclotron. In order to evaluate the quality of the beams extracted from ion sources quickly, we developed the Pepper-Pot type Emittance Monitor at the RCNP. After improving an analysis method for emittance estimation using LabVIEW, we achieved a measurement frequency of 4 Hz.
