A Swept Langmuir Probe at 150 V / μsec

Abstract
A technique is presented for generating a complete Langmuir probe characteristic in 2 μsec with sweep speeds greater than 150 V/μsec. Probe construction with stable lead capacitance is necessary when compensating for the cable displacement current with a current transformer. The probe characteristic is displayed using the X‐Y capabilities of a 'scope and results are given for an electron cyclotron resonance heated hydrogen plasma confined in a toroidal quadrupole.
