Combinaion of PBFA I lines in a disk feed
Sandia National Laboratories Particles Beam Accelerator PBFA I has 36 radially converging magnetically self-insulated triplate transmission lines. Each of these magnetically insulated transmission lines (MITL's) has a tapered section at the output which changes the configuration from triplate to coaxial. Some ion diodes proposed for testing on PBFA I are cylindrically symmetric about the machine center and require the combination of the individual PBFA I lines a triplate disk feed. The combination of many MITL's presents two potential problems. There is the possibility that an early pulse from one line might reflect into nearby lines destroying the magnetic insulation in these lines. A computer simulation of a two-line combination showed serious losses, but the line coupling in this 2-D simulation was significantly different. Another possibility is loss of energy in the regions of zero magnetic field between individual lines at the beginning of the disk feed. An experiment on PBFA I is reported which combined two MITL's into a sector of a disk which showed current losses of 12% or less in the later line for pulse arrival time differences of zero to 200 ns, and no evidence of significant losses in the regions of low magnetic filed.
