Abstract :
Simulation codes are commonly used in the design and enhancement of TWT performance. A suite of TWT design codes developed under ONR-NRL sponsorship has been validated against 750 watt Ku-band communication TWTs manufactured by CPI (VTU-6397). The design code suite includes: MICHELLE, a 3D gun and collector code; CTLSS, a 3D cold test code; CHRISTIN, 1D & 3D large signal codes; and mPPM/lesPPM, magnet design code. The corresponding role of each code in TWT simulation is described in this paper.
