An impedance reduction had been detected in the J-PARC RCS cavity 7 in January 2009. After taking out and opening the cavity tanks, buckling at the inner radius was detected at some of the MA cores. Here we describe the development and application of magnetic sensors, which were expected to detect the buckling of the cores in the stainless steel water tanks without the need for taking out and opening them.
