The acceleration of different specific charge ions in the heavy ions RFQ linac.

The acceleration of ions with different specific charge in the heavy ions RFQ linac has enabled to determine both several linacs experimental characteristics and the ion beam parameters at the injector output which is undetermined by the another technique. They are: the dependence of the capture efficiency on specific charge of ion; the magnitude of the limit current for the linac and its dependence on the ion specific charge. In particular there is the possibility to fmd non-linear disturbance in RF field distribution. The technique is acceptable to test any RFQ accelerator in action.
