• In order to measure the number density of charged particles in a high speedflow on slightly ionized argon, the hollow electric collector probe has been shownto be useful. This work is to investigate effects of the dimension of hollow probesand the strength of applied electric field on capture of charged particles. Theexperimental results show that the lower aspect ratio (=the ratio of the distancebetween electrodes to the electrode length) and the higher applied electric fieldare effective for capturing all charged particles entering into the probe. Evenwhen an ion number density is relatively high (< 10" cm '), the hollow probecan be used for measurement of plasma density in a flowing plasma, though thereare restrictions on minimum dimensions of probes and maximum strength ofapplied electric field.
