The invention discloses a superconductive cyclotron extraction region beam measurement detection target head, which comprises a probe target head and a fixation structure. The probe target head is formed by a multi-wire probe, a ceramic block and a connecting rod. One end of each tungsten wire passes through a through hole in the ceramic block and extends into the connecting rod; each tungsten wire is fixedly arranged in the ceramic block through welding; and the ceramic block is fixedly arranged in one end of the connecting rod through welding. The fixation structure comprises an aluminum alloy connecting piece and a drive rod. The connecting rod and the drive rod are connected through the aluminum alloy connecting piece. The detection target head can carry out measurement based on intensity of electrical signals on different wires and through a point motion mode of the drive rod to obtain axial and radial position information of the beam, so that beam debugging can be carried out, and stable and effective operation of an accelerator is realized; and the detection target head has the advantages of high resolution, high precision, simple measurement and capable of replacing the probe without opening the cavity.
