Ion sources based on Penning discharge cells are now widely used in small-size pulsed neutron generators of geophysical well-logging apparatus. The operating efficiency of the apparatus is associated with the amplitude and time parameters of the neutron pulse of the generator, which depend on the gas pressure, geometry of the electrode systems, and other factors. Therefore it is necessary to investigate Penning discharge regimes in the context of control and regulation of the working gas (hydrogen) pressure as well as to measure the amplitude-time characteristics of the discharge as a function of the periodic-pulse power supply parameters. The stable discharge ignition regimes in the ion source were determined experimentally, and it was shown that different discharge regimes exist. The operating regimes of ion sources with a descending voltage dependence of the discharge current were revealed at heightened gas pressure.

研究微型离子源中彭宁放电的幅时特性

基于潘宁放电室的离子源现已广泛应用于地球物理测井仪的小型脉冲中子发生器中。设备的运行效率与发生器的中子脉冲的幅度和时间参数有关，这些参数取决于气体压力、电极系统的几何形状和其他因素。因此，有必要在控制和调节工作气体（氢气）压力的背景下研究 Penning 放电状态，并测量放电的幅度-时间特性作为周期脉冲电源参数的函数。通过实验确定了离子源中的稳定放电点火方式，结果表明存在不同的放电方式。
