AJDISK is a 1D large signal klystron simulator developed at SLAC. A brief discussion of AJDISK's simulation algorithm is given and [1] is fully developed to show how AJDISK was extended to enable sheet beam klystron simulations. The primary requirement for extending "disk" simulators to sheet beam simulators is a space charge equation. Therefore, the electric field due to an infinitely thin plate of charge (infinitely thin in the direction of propagation) in a rectangular drift tube is derived. The derivation is extended to a "2D" space charge equation in which the plate is split into a series of rods with varying positions in y. The derived equations are compared with numerical simulations and measurement.

“…It turns out that for this condition the circuit impedance must be approximately equal to the dc beam impedance. The bandwidth of the drive and intermediate cavities is narrower unless some resistive loading is coupled in, but by stagger tuning it is possible to achieve bandwidths limited only by the output cavity [5]. This bandwidth can be improved fractionally by coupled cavity broadbanding techniques [19][20][21].…”

“…Over an extended period, several design categories for enhancing bandwidth in Klystron have been researched [8][9][10][11][12][13][14][15][16]. Sheet beam type Klystrons, extended interaction type Klystrons, and triaxial Klystrons are popular candidates among them [17][18][19][20][21].…”

The V-band frequencies are becoming popular due to their application potential towards secure high data rate communications. This article reports bandwidth enhancement of an 11-cavity V-band Klystron amplifier employing staggered tuning. A systematic approach is presented to stagger-tune the periodically allocated multiple cavities of the Klystron operating at 60.1 GHz. Using the three-dimensional particle-in-cell (PIC) simulation, it is shown that, employing the proposed approach, the −3 dB bandwidth of the device (with peak tuned configuration) has been increased from 165 MHz to 540 MHz, demonstrating a 260% increment. The −1 dB bandwidth of the device is estimated to be 270 MHz. The proposed approach of stagger tuning may be employed for similar devices employing multiple RF cavities to meet the requirement of wide bandwidth.
