An IPv6 tunnel broker is a service or organization that provides a way for users to access the IPv6 internet when their internet service provider (ISP) does not offer native IPv6 connectivity. This is typically done by encapsulating IPv6 packets within IPv4 packets and routing them through a tunnel to a remote server that has … Read more
In the context of nuclear fusion, the cross-section refers to the measure of the likelihood that two atomic nuclei will undergo a fusion reaction when they collide. It is typically denoted by the symbol “σ” (sigma) and has units of area. The cross-section for nuclear fusion depends on various factors, including the types of nuclei … Read more
from Wolfram Mathematica to JavaScript might require understanding the specific functionality of both languages, as they have different syntax and capabilities. Certainly! The FortranForm function in Mathematica is used to convert expressions into a form that is more suitable for use in Fortran code. It ensures that the syntax and formatting match the Fortran programming … Read more
The Coulomb potential barrier, also known as the Coulomb barrier, is a concept in physics that refers to the energy barrier that must be overcome for two charged particles to interact or come close enough to undergo a specific process, such as nuclear reactions or particle interactions. It arises due to the electrostatic repulsion or … Read more
Matrix is a tool to deal with the linear algebra. Vector is usually used to describe most of the physical quantities those have both the direction and amplitude. The vector operations are usually very complicated in the vector algebra. A vector is a simple matrix. I try to obtain the matrix form of vector operation … Read more
Electron cyclotron resonance heating is the simplest of the radio frequency heating methods. There is no evanescent region between the antenna and the plasma. However there may be cut-offs in the plasma. It turns out to provide remarkable advantages for heating of fusion plasma. An electromagnetic wave in the electron cyclotron resonance frequency range always … Read more
Circular waveguides offer implementation advantages over rectangular wave guide is that installation is much simpler when forming runs of turns and offsets. The uniform section in the gyrotron cavity is a circular waveguide. The working mode is usually a transverse electric mode in the cavity. Here is a calculator for the Transverse Electric mode in … Read more
Gyrotron is a microwave oscillators. It changes the DC energy to high power millimetre microwave. It has been successfully used in the magnetic confinement thermonuclear fusion research as the microwave source for the electron cyclotron resonance heating and current drive. A typical gyrotron cavity consists of a central section and one taper section at both … Read more
Weak form is an important tool for the analysis of electromagnetic problems. It is a bridge from the partial differential equations to the linear algebra. For example, the Helmholtz equation with wave number \(k_c\) is \(\nabla_t^2 \phi+k_c^2 \phi=0\) It is so-called “strong form”, in which the unknow is in the 2nd order differential operator. It … Read more
