The characteristics of the induced voltage of the high power disk amplifier, which is not grounding (suspended), is researched experimentally. Results show that the peak value of the induced voltage is dominated by the capacitance between the flash lamp and the cavity and the number of flash lamps in the amplifier, and the independent cavities don′t affect each other directly. Exprimental study on induction properties of the amplifier under a variety of grounding methods is conducted, and a grounding plan of wholly grounding the amplifier with the internal and external cavities electrically integrated is demonstrated, which is successfully applied to the 350 mm disk amplifier of the ninth beam of SGⅡ. The possibility of electrical breakdown inside the amplifier is eliminated radically, and the induced voltage of the amplifier is reduced to 18% of that when the amplifier is suspended. As a result, the reliability and safety of the disk amplifier are improved obviously, the compactness and cleanliness of the amplifier are also improved simultaneously. Since this grounding plan is adopted, the 350 mm amplifiers have operated reliably and safely for more than 400 shots without any electrical breakdown and interference.

实验研究了高功率片状放大器不接地（悬浮状态）时感应电压的变化规律，结果表明：感应电压的大小主要受到金属腔体与氙灯之间的分布电容、放大器充电电压以及氙灯数量的影响；腔体之间不产生直接影响关系。实验研究了放大器在多种接地方式下的感应特性，提出了放大器内外腔电一体化并整体接地的接地方案，并将其成功应用到了神光 Ⅱ 第9路350 mm片状放大器中，从根本上消除了放大器内部电击穿的可能性，并将放大器的感应电压降低到悬浮状态下的18%，提高了片状放大器运行可靠性和安全性，同时有助于改善放大器的紧凑性和洁净度。采用这种接地方案以来，350 mm放大器可靠运行400多发次，未出现电击穿或干扰现象。

A new testing system was developed for the instantaneous parameter of multiple pulses of Xe flashlamps discharge system, which can replace the traditional testing mode of manifold paths oscillograph. It had a powerful function and was easy to operate, directly perceived through the sense, resisted disturb. It had a enormous data bank for looking for to all computers of a network.
