Reproduction of the head of the Robbins target at ISOLDE

A new type of liquid metal target for the isotope separator, ISOLDE. An alternating current (the high current leads can be seen behind the target) keeps the metal at this glowing temperature in a tantalum container which is placed axiaily in the path of the SC beam, ions of barium, cesium, xenon, iodine and tellurium, for example, can be obtained from a lanthanum target.
