    A design of a superconducting accelerator for a pulsed positron beam of ∼1 MeV for positron annihilation lifetime spectroscopy is proposed. The total system can be extremely small with an application of super-conducting technology. Both a miniaturization and easy maintenance of the accelerator can be achieved by usage of a small liquidless refrigerator for cooling of a superconducting RF cavity. Moreover, the operation duty cycle of the superconducting cavity is ∼100% which is much larger than that of a normal conducting one. The required RF power to drive the system is ∼10 W, therefore a large-size klystron is not necessary. The designed system including a slow positron source is small (∼2 m3 ) enough to be used in a general laboratory.
