Abstract
In a multipole linear accelerator such as of a quadrupole type, fine positional adjustment of the tip portions of the electrodes constituting the multipole structure can be made with electric contact kept substantially unaffected between the electrodes and the cavity drum in which the electrodes are mounted. Each of the electrodes are provided with a series of contact plates on both sides of the root portion of the electrode over the whole length thereof. Each of the contact plates, which are held to the root portion of the electrode by means of an adjusting screw bolt, slantwise bridges the root portion of the electrode and the inner surface of the cavity drum with elastic contact pieces interposed. Tightening or loosing the adjusting screw bolts on both sides of the electrode displaces the electrode with electric contact kept unchanged between the electrode and the cavity drum by the elastic effect of the above contact pieces made to interpose between the contact plates and both the electrodes and the cavity drum.
