This is a preview for the new '''MathML rendering mode''' (with SVG fallback), which is availble in production for registered users.
A '''Cherenkov (Čerenkov) detector''' is a [[particle detector]] using the mass-dependent threshold energy of [[Cherenkov radiation]]. This allows a discrimination between a lighter particle (which does radiate) and a heavier particle (which does not radiate).


It is a more advanced form of [[scintillation counter]]. A particle passing through a material at a velocity greater than that at which light can travel through the material emits light. This is similar to the production of a [[sonic boom]] when an airplane is traveling through the air faster than sound waves can move through the air. This light is emitted in a cone about the direction in which the particle is moving. The angle of the cone, <math>\scriptstyle \theta_c </math>, is a direct measure of the particle's velocity through the formula

Registered users will be able to choose between the following three rendering modes:  


where <math>\scriptstyle c</math> is the [[speed of light]], and <math>\scriptstyle n </math> is the [[refractive index]] of the medium.  Alternatively, if the momentum of the particle is known (from magnetic bending) the Cherenkov's information on the particle's velocity enables the mass to be deduced so that the particle can be identified.

This is a preview for the new MathML rendering mode (with SVG fallback), which is availble in production for registered users.

If you would like use the MathML rendering mode, you need a wikipedia user account that can be registered here [[1]]

  • Only registered users will be able to execute this rendering mode.
  • Note: you need not enter a email address (nor any other private information). Please do not use a password that you use elsewhere.

Registered users will be able to choose between the following three rendering modes:

MathML

E=mc2


Follow this link to change your Math rendering settings. You can also add a Custom CSS to force the MathML/SVG rendering or select different font families. See these examples.

Demos

Here are some demos:

To test the MathML, PNG, and source rendering modes, please go to one of the following test pages:
