RPA and Langmuir probe measurements were made in the near-field plume on the axis of a hollow cathode assembly (HCA). High-energy ions were detected at low-powers consistent with the detection of such ions at high powers in previous investigations. The absence of a potential hill in the testing conditions suggests that an additional source of high energy ions may be charge exchange ions in the luminous region of the cathode discharge. The peaks in the RPA data tend to support this theory. In addition, it was established that the conditions in the near-field of the HCA expellent would be condusive to laser-induced fluorescence (LIF) measurement.
