Abstract
In the radioactive-beam facility at INS, unstable nuclei with a charge-to-mass ratio greater than 1/10 are accelerated from 170 to 1046 keV/u by an interdigital-H linac. Designed IH linac consists of four acceleration tanks and three sets of quadrupole triplets placed between tanks. Output energy is continuously variable by changing rf power and phase of the last operating tank. On the basis of an equivalent circuit analysis, low power models were constructed. For the tank-4 model, resonant frequency close to the design value was obtained by adjusting the size of the magnetic flux inducer. One set of the quadrupole triplet was constructed to investigate the coupling effect between an adjacent magnets and the effect of saturated magnetic flux on the field gradient. In this paper, a summary of the studies done so far and a present status on the IH linac are described together with a brief introduction of the new facility. (author).
