Development of a compact high-density blue core helicon plasma device under 2000 G magnetic field of ring permanent magnets
文献摘要：
A helicon wave plasma source in a tube of ring permanent magnets(PMs)has been constructed to study the effect of the configuration of the magnetic field with zero magnetic points on plasma parameters.This device also serves as an exploration platform for a simple,compact helicon wave plasma source adaptable to engineering applications.A small-diameter(26 mm)high-density(～1018 m-3)blue core plasma is produced in～1 Pa argon by helicon RF(radio-frequency)discharge using a Nagoya Ⅲ antenna under magnetic field(～2 kG)of compact ring PMs(length～204 mm).Operational parameters,i.e.RF power and neutral gas pressure are scanned and plasma density is measured by an RF compensated probe to explore the operating characteristics of the device.Iconic feature of a helicon discharge,such as blue core plasmas and E-H-W mode transitions are well observed in the device,despite the wavelength calculated using the conventional dispersion relation of a bounded whistler waves(Chen 1991 Plasma Phys.Control.Fusion 33 339)is order of magnitudes longer than the length of the plasma in this device which seems to suggest that such helicon device is impossible.Surprisingly,the wavelength calculated by the unbounded whistle wave dispersion formula in turn suggests the occurrence of a half wavelength resonance.
