已制成一种使用5949闸流管阴极部件的大功率氢闸流管栅——阳极结构。其中一个这样的管子在2000 A,32 KV,1400c/s,脉宽0.3μs吋工作了10小时。而另一只则在1000 A,100 KV,工作比0.00004时工作了220小时。此工作比为我们实验调制器线路目前条件所限.对触发器的要求是:在2.5μs脉宽,50Ω内阻时输出2KV。当我们用一台Tektronix 517示波器测量管子前沿抖动时,它为0。示波器用50ns/cm的速度扫描。阳极延迟时间在1/4-1/2μs的范围内。阳-栅极的几何形状是为获得最小的栅极-阳极电容而设计的,这就使管子能在较高的重复频率下工作。这种结构在100 KV之内场致发射通常不明显。
A high-power thyristor grid-anode structure using a 5949 thyristor cathode has been fabricated. One of these tubes worked for 10 hours at 2000 A, 32 KV, 1400 c / s, 0.3 μs pulse width. While the other worked at 1000 A, 100 KV for 220 hours at 0.00004. This work is more limited than the current conditions of our experimental modulator line. The requirements for the flip-flop are: 2KV at 2.5μs pulse width with 50Ω internal resistance. It is zero when we measure the pipe edge jitter with a Tektronix 517 oscilloscope. Oscilloscope with 50ns / cm speed scanning. The anode delay time is in the range of 1 / 4-1 / 2μs. The geometry of the anode-gate is designed to achieve the smallest gate-anode capacitance, which allows the tube to operate at higher repetition rates. Field emission of this structure within 100 KV is usually not obvious.
