  An asynchronous accelerator is described, in which the principle of its
operation permits the active longitudinal bunch compression of accelerated
proton beams, to overcome the space charge limitation effects of intense
bunches. It is shown that accelerated bunches from an RFQ linac can be adapted
for Asynchronac injection for a multiple of choices in the acceleration
frequencies of the RFQ and the Asynchronac. The offered new type of accelerator
system is especially suitable to accelerate proton beams for up to 100MeV
energy and hundreds of mA average current.
