TRIFL: A design tool for modeling complex magnetically insulated transmission line geometries
- Sandia National Labs. Albuquerque, NM (United States)
Vacuum power flow in modern high-power pulsed accelerator transmission lines requires field stresses at the conductors that are so high that negative surfaces become space-charge-limited electron emitters. The performance of these lines can be calculated using two- and three-dimensional, time-dependent, particle-in-cell electromagnetic codes such a TWOQUICK and QUICKSILVER. Extensive design of complex systems using these simulation codes would be extremely expensive and, perhaps, impossible for many of the new pulsed power systems being planned. An analytic model has been developed which predicts the behavior of magnetically insulated transmission lines. The model uses flow impedance parameters with an expanded set of Telegrapher`s equations to calculate radial currents in the transmission lines. This model has been implemented in a code, TRIFL (TRIple-equation-FLow model), on workstations and PC`s and allows one to do detailed designed studies on systems far too complex for similar treatment using a PIC code. TRIFL has been used to design hardware for the PBFA-X accelerator and to analyze PBFA-X data.
