Abstract

An intense slow positron beam has been produced for the first time using a compact cyclotron. Used in an ondashline mode, an intense positron source has been produced by making use of the ²⁷Al(p,n)²⁷Si reaction. A transmission type target system has been developed in order to avoid decreases in the slow positron beam intensity due to the damage induced in the moderator by proton irradiation. In the near future beam intensities of the order of 10⁷-10⁹ slow e⁺/s are expected from this system.
