Transverse multipole moments (quadrupole and more) of the beam may give important informations of the beam such as beam sizes, nonlinear resonances and so on. However higher moments are difficult to measure because signal-to-noise-ratio becomes smaller proportional to the n-th order of the beam-radius-to-vacuum-duct-radius ratio. In order to increase the SNR and to extend the multipole order, we developed and installed a 16 electrode beam monitor in the J-PARC MR, which consists of guard-potential-separated 16 striplines. The calibration method, beam test results will be presented.
