There is an accuracy limit of LLRF control over cavity rf phase and amplitude. This limited accuracy of control gives rise to beam energy and phase jitter, emittance growth, and beam loss.

DTL of SNS linac accelerates the 2.5 MeV H/sup -/ beam from the RFQ and the MEBT to 86 MeV. For longitudinal setpoint, two standard phase scan methods will be used, because they are complementary. Numerical simulation using the Parmila code indicates that only the phase scan with the absorber and collector is effective for DTL tank 6. But for the rest of the DTL tanks, both methods are effective.Show More

The structure is of the rod and post type, novel in that each of four rods is supported by two posts oriented radially with respect to the beam axis. Although the geometry has four-fold rotation symmetry, the dipole-quadrupole mode splitting is large, giving good mechanical tolerances. The ...Show More
