The present invention relates to a high efficiency hollow cathode and a cathode system applying the same, and comprises: a tube comprising at least two refractory metal parts; a gas providing unit and a gas outlet which are respectively formed at the distal ends of the tube; and an insert mounted inside the tube. According to the present invention, since the present invention constitutes a hollow cathode using more than two substances, the present invention can not only enhance thermal stability, lifespan and efficiency, but also can reduce costs accordingly.
