Abstract
A new RFQ linac structure extends the useful range of beam velocity by a factor of 2 to 4 and beam energy by a factor of 4 to 16. Four-finger electrodes extend into each accelerating cell and provide quadrupole focusing of beam particles along a beam axis. The finger electrodes of adjacent cells also provide quadrupole acceleration of the beam particles along the beam axis. The finger of adjacent cells are oriented in accordance with a prescribed pattern. The pattern orientation of the fingers provides an additional degree of freedom that allows the periodcity of the focal structure to be independent of the periodicity of the accelerating structure. This makes it possible to double the rf frequency periodically to enhance the acceleration rate while holding the focusing strength constant.
