AB - The KHIMA (Korea Heavy Ion Medical Accelerator) project is launched to construct the carbon and proton beam base ion therapy machine. It, which consists of the injector with RFQ and IH-DTL linacs, medium beam transport line, synchrotron, and high energy beam transport line, will be provided the carbon beam up to 430 MeV/u and proton beam up to 230 MeV for cancer therapy. The high precision beam position monitor is required to match and control the beam trajectory for the beam injection and closed orbit in synchrotron. It was also used for measuring the beta-function, tune, and chromaticity. Since the bunch length at heavy ion synchrotron is relatively long, a few meters, a box-like device with long plates of typically 20 cm is used to enhance the signal strength and to get a precise linear dependence with respect to the beam displacement. In this presentation, we show the electromagnetic design of the electrode and surroundings to satisfy the resolution of 100 um, the criteria for mechanical aspect to satisfy the position accuracy of 200 um, the measurement result of position accuracy by using the wire test-bench, and the beam-test results with long (~ 1.6 us) electron beam in PAL.
