In this case, the emittance is determined by the initial particle distribution.

The emittance of an object quantifies how much light is emitted by it.

Indus-2 lattice has been designed in such a way as to give low beam emittance and high brightness.

The dimension parallel to the motion of the particle is called the longitudinal emittance.

It is often more useful to consider the normalised emittance:

Thermal emittance is the ability to emit absorbed heat.

One should distinguish the emittance of a single particle to that of the whole beam.

The cavities must have a large aperture in order to avoid significant scraping from the high emittance beam.

The program does not, however, specify minimum requirements for solar reflectance or thermal emittance.

Thus overall the angular spread and hence the geometric emittance in the beam will be reduced.

For building products, thermal emittance measurements are taken for wavelengths in the infrared.

Most building materials have a high emittance ε, so all surfaces in the room can be assumed to be black.

This is the single particle emittance.

The normalised emittance does not change as a function of energy and so can track beam degradation if the particles are accelerated.

More elaborate analysis of the emitted visual radiation may allow for the determination of and emittance.

During its peak fragrance emittance in the early morning, the scent is fruity, resembling an apple.

Between 1980 and 1982 regulations governing RF emittance from home computers were phased in.

Thus the normalised beam emittance is reduced.

A low emittance particle beam is a beam where the particles are confined to a small distance and have nearly the same momentum.

In a synchrotron light source, low emittance means that the resulting x-ray beam will be small, and result in higher brightness.

The arithmetic definition of a transverse emittance is:

Similarly, luminous emittance is the luminous flux per unit area emitted from a surface.

Luminous emittance is also known as luminous exitance.

The most energy-efficient roofs also have high emittance, which means they're efficient at releasing any solar heat they have absorbed.
