Parallel computing for helix TWT

Designing an octave bandwidth helix TWT for phase and gain matched operation in the EHF region presents many obstacles, the dimensional controls which must be imposed in the design and fabrication of parallel-operating are difficult. Parallel computing offers the possibility to evaluate the effect that slow-wave structure parameter and operating parameter variations, such as manufacturing tolerances, this will enable manufacturers to determine the cost effectiveness of controlling the dimensions of the component parts of the TWT. Computation of beam and wave nonlinearly interaction should cost many time. For analyzing the gain and phase matched characterristic, parallel computing is necessary.
