    • In a Hall thruster 10, an acceleration channel 12 ionizes propellant flowing into an annular discharge space 11 to generate ions, and accelerates and discharges the generated ions. A distributor 37 supplies propellant from a plurality of holes 13 arranged azimuthally, via an anode 14 penetrating to the discharge space 11 of the acceleration channel 12, to the discharge space 11 of the acceleration channel 12, an amount of the propellant varying according to positions of the plurality of holes 13, thereby generating a plurality of regions, between adjacent ones of which the mass flow rate of the propellant is different, azimuthally in the discharge space 11 of the acceleration channel 12. During that time, the distributor 37 adjusts, with respect to the mass flow rate of the propellant in the discharge space 11 of the acceleration channel 12, a differential within a range of 5 to 15% between the mass flow rate of the propellant in a region with a large mass flow rate of the propellant and the mass flow rate of the propellant in a region with a small mass flow rate of the propellant. Thus, the width of a operation parameter region with reduced discharge current oscillation of the Hall thruster 10 is expanded.
    • 在霍尔推进器10中,加速通道12将流入环形放电空间11的推进剂电离以产生离子,并加速和排出所产生的离子。 分配器37经由穿过加速通道12的放电空间11的阳极14方位排列的多个孔13向加速通道12的放电空间11供给推进剂,推进剂的量根据位置而变化 ,从而在加速通道12的放电空间11中在方位角之间产生多个区域,其中相邻的区域之间的推进剂的质量流量不同。在此期间,分配器37调整, 相对于加速通道12的放电空间11中的推进剂的质量流量,在推进剂的质量流量与质量流量的大的质量流量之间的差为5〜15% 推进剂和推进剂在推进剂质量流量较小的区域中的质量流量。 因此,扩大了霍尔推进器10的放电电流振荡减小的动作参数区域的宽度。
