beam with cross section
1Cross section (physics) — A cross section is the effective area which governs the probability of some scattering or absorption event. Together with particle density and path length, it can be used to predict the total scattering probability via the Beer Lambert law. In… …
2cross-section — /ˈkrɒs sɛkʃən / (say kros sekshuhn) noun 1. a section made by a plane cutting anything transversely, especially at right angles to the longest axis. 2. a piece so cut off. 3. the act of cutting anything across. 4. a typical selection; a sample… …
3Neutron cross section — Science with Neutrons Foundations Neutron temperature Flux · Radiation  …
4Nuclear cross section — The nuclear cross section of a nucleus is used to characterize the probability that a nuclear reaction will occur. The concept of a nuclear cross section can be quantified physically in terms of characteristic area where a larger area means a… …
5Optical cross section — or OCS is a value which describes the maximum amount of optical flux reflected back to the source. The standard unit of measurement is . It is dependent on the geometry and the reflectivity at a particular wavelength of an object. Optical cross… …
6R (cross section ratio) — R is the ratio of the hadronic cross section to the muon cross section in electron positron collisions::R = frac{sigma^{(0)}(e^+e^ ightarrow mathrm{hadrons})}{sigma^{(0)}(e^+e^ ightarrow mu^+mu^ )},where the superscript (0) indicates that the… …
7Cross brace — is the cross beam connecting between arches meant to add rigidity to construction of mining tunnels, more often tubular round diameter (as a rule, it is made of scraps of pipes), on the ends with clips or apertures for screw fastening; serves as… …
8Beam propagation method — (BPM) refers to a computational technique in Electromagnetics, usedto solve the Helmholtz equation under conditions of a time harmonic wave. BPM works under slowly varying envelope approximation, for linear and nonlinear equations.The beam… …
9Beam (structure) — A statically determinate beam, bending (sagging) under an evenly distributed load. A beam is a horizontal structural element that is capable of withstanding load primarily by resisting bending. The bending force induced into the material of the… …
10Beam diameter — The beam diameter or beam width of an electromagnetic beam is the diameter along any specified line that is perpendicular to the beam axis and intersects it. Since beams typically do not have sharp edges, the diameter can be obtained in many… …
