High Power Model Fabrication of Biperiodic L-Support Disk-and-Washer Structure
H. Ao, Y. Iwashita, T. Shirai +5
The high power test model of biperiodic L-support disk-and- washer was fabricated. Among some trouble in the fabrication, the main one was a vacuum leak in a brazing process. The r…

DFQ--Double Frequency RFQ
Y. Iwashita
RFQ with a harmonic higher order quadrupole mode is studied. Assuming that we superpose a higher order mode with twice the frequency of the fundamental mode, a sawtooth waveform is…

Study of Multiple-Beam RFQ
V. Kapin, M. Inoue, Y. Iwashita +1
There are applications, which require MeV-range multiple-beams consisting of a large number of identical highly packed beamlets. The multiple-beam RFQ (MB-RFQ) arranged as a matrix…
