abstract = {{In this paper, present status of improvements of the impedance matching circuit for the J-PARC main ring injection kicker magnet to achieve 1.3MW beam operation planed after 2022 is described. In order to reduce the temperature-rise of resistors under the higher repetition rate pulse excitation, number of paralleled resistors was doubled and volume of each resistor was enlarged 2.6 times. Ceramic-made beads with diameter of 3 mm were filled in the cylinder of the resistor to increase the heat conductivity. An aluminum-made water-cooled heat sink was attached to the resistors directly and an air-cooling fan was mounted to the side of the box containing the resistors. All resistors and their support structure have been replaced in March 2022. Temperature-rise of resistors during continuous pulse excitation was measured by commercial thermo camera and compared with numerical calculations. In addition, predictions about the beam induced heating of the resistors are discussed.}},
