摘要

模拟了0.14 THz相对论返波管中电子束与氩气相互作用产生等离子体的过程, 研究了在不同气压条件下, 等离子体对相对论返波管的输出功率、频率以及起振时间的影响. 模拟结果表明, 等离子体背景能引起太赫兹波段真空电子器件脉冲缩短, 并出现新的频率分量; 适当地注入等离子体能减少0.14 THz相对论返波管的起振时间, 提高器件的输出功率.

In this paper, a 0.14 THz relativistic backward-wave oscillator (RBWO) filled with neutral argon gas is simulated by using the UNIPIC code. The effects of plasma on the output power, frequency, and the start-oscillation time of the RBWO filled with different-pressure gases are studied. The simulation result shows that the background plasma can cause the pulse-shortening and new frequency appearing in the 0.14 THz RBWO. Appropriate plasma infusion can reduce the start-oscillation time and increase the output power of 0.14 THz RBWO.
