The invention provides a patient shuttle system and an irradiation system for particle therapy. A patient shuttle system of one embodiment of the invention includes: a patient table () adapted to carry a patient; a patient table drive unit () that moves and/or rotates the patient table; and a transfer unit () having a base () on which the patient table drive unit is placed. In a home position state of the patient shuttle system (), the patient table and first and second arms of the patient table drive unit are configured to be folded in the height direction (Z-axis). A robot arm base connected to the second arm is fixed at a position off the center of the base in plan view, and thereby a helper space () where a helper may ride is secured on the base. The robot arm base is fixed in a recess () provided in the base.

The objective of the invention is to provide a microwave tube, or the like, wherein gas adsorption action of a getter may be satisfactorily performed independently from a microwave amplification operation. In order to solve this problem, this microwave electron tube comprises: a helix wherein a microwave may progress oriented from an input section to an output section within a helical tube; an electron gun emitting an electron flow oriented toward the helix; a focusing device causing the electron flow to traverse the vicinity of the helix in the direction of a collector; the collector absorbing the electron flow; and a getter having a heater insulated from the cathode provided in the electron gun.
