Characterization of a One Hundred Watt, Long Lifetime Hall Effect Thruster for Small Spacecraft

Effects of Magnetic Shielding Configuration on Discharge Characteristics and Performance of a 60 mm-Diameter Low-Power Hall Thruster

“…1. The magnetic shielding topology could take full advantage of the isothermality of the magnetic field lines (Szabo et al 2017), as shown in Eq. 1.…”

“…And the integral of the electric field along the magnetic field line from the centerline of the discharge channel can be expressed as Eq. 2, the thermalized potential equation, where Φ 0 and T e0 represent the plasma potential and the electron temperature in the centerline of the discharge channel, respectively (Szabo et al 2017).…”

“…2) was designed based on its unshielded counterpart. Giving that application of magnetic shielding configuration on low-power Hall thruster will decrease the efficiency, found in BHT-100 and ISCT200-Ms (Grimaud and Mazouffre 2018;Szabo et al 2017), and the strict requirement for magnetic components, a partial magnetic shielding configuration was achieved, in which part of the magnetic lines were allowed to intersect the walls of acceleration region. The magnetic configurations of LHT-60 and LHT-60M are shown in Fig.…”

“…Grimaud designed a 200-W Hall thruster under magnetic configuration called ISCT200-Ms, producing 11.4 mN thrust and 920 s special impulse (Grimaud and Mazouffre 2018). Busek developed a 100-W magnetic shielding Hall thruster, which has a performance of 6.57 mN and 1010 s special impulse (Szabo et al 2017). Expect for the feasibility of the magnetic shielding configuration, low efficiency was measured in these thrusters.…”

“…7. The selected thrusters are, in addition to the ISCT100: the BHT-100 American HT [34], the SPT-20 Ukrainian HT [35], the SPT-30 Russian HT [19] and the PSAC 100 [36] from Singapore. The ISCT100 has a relatively flat performance curve over a wide range of operating conditions, i.e.…”
