AB - Hadron experimental facility(HD hall) at Japan Proton Accelerator Research Complex (J-PARC) is designed to provide high intensity beam for particle and nuclear physics. Slow-extracted proton beam(2 second spill per 6 seconds) from main ring is injected to a production target at the HD hall. On May 2013, proton beam was instantaneously extracted to the HD hall in 5 milliseconds. The short pulse beam melted the production target. After the accident, the beam operation was stopped at the HD hall. For the recovery of the HD hall, we upgraded the beam line of the HD hall in many aspects to sustain the abnormal beam injection. The monitor system of the beam line was also upgraded to detect the abnormal beam injection. The rate monitor of second particles from the target was prepared to detect short pulse injection. The beam profile monitor was upgraded to measure at several times during one pulse to detect a sudden change of the beam profile. The beam loss monitor was upgraded to read out always to detect unexpected high intensity beam promptly. These signals were included in the interlock system. In this paper, the detail of the beam monitor system upgrade will be reported.
