WebSep 15, 2004 · 디바이 차폐(Debye sheath)는 플라즈마의 특성에 의해 내부의 전하가 감지되지 않는 현상으로, 플라즈마 내부의 전하 주변으로 . 반대부호를 가진 전하들이 모이면서 이 전하가 만들어낸 전기장을 상쇄하기 때문에 나타나는 현상입니다. WebA Debye sphere is a volume whose radius is the Debye length. Debye length is an important parameter in plasma physics, electrolytes, and colloids ( DLVO theory ). The corresponding Debye screening wave vector for particles of density , charge at a temperature is given by in Gaussian units. Expressions in MKS units will be given below.

WebDec 6, 2024 · The Debye sheath is known to vanish completely in magnetised plasmas for a sufficiently small electron gyroradius and small angle between the magnetic field and the wall. This angle depends on the current onto the wall. When the Debye sheath vanishes, there is still a potential drop between the wall and the plasma across the magnetic … WebThe properties of sheaths formed on the divertor plates have a strong influence on plasma behavior in the scrape-off-layer. What makes these properties quite different from those of standard Debye sheaths is that the magnetic field in the SOL intersects divertor plates at a shallow angle.

Let us imagine a sphere about one of its electrons, and compare the number of electrons crossing this sphere with and without Coulomb repulsion. With repulsion, this number is smaller. Therefore, according to Gauss theorem, the apparent charge of the first electron is smaller than in the absence of repulsion.
