Secondary Emission
In particle physics, secondary emission is a phenomenon where primary incident particles of sufficient energy, when hitting a surface or passing through some material, induce the emission of secondary particles. The term often refers to the emission of electrons when charged particles like electrons or ions in a vacuum tube strike a metal surface; these are called secondary electrons. In this case, the number of secondary electrons emitted per incident particle is called secondary emission yield. If the secondary particles are ions, the effect is termed ''secondary ion emission''. Secondary electron emission is used in photomultiplier tubes and image intensifier tubes to amplify the small number of photoelectrons produced by photoemission, making the tube more sensitive. It also occurs as an undesirable side effect in electronic vacuum tubes when electrons from the cathode strike the anode, and can cause parasitic oscillation.

Secondary (football)
In gridiron football, defensive backs (DBs), also called the secondary, are the players on the defensive side of the ball who play farthest back from the line of scrimmage. They are distinguished from the other two sets of defensive players, the defensive linemen who play directly on the line of scrimmage, and the linebackers, who play in the middle of the defense, between the defensive line and the defensive backs. Among the defensive backs, there are two main types, cornerbacks, which play nearer the line of scrimmage and the sideline, whose main role is to cover the opposing team's wide receivers, and the safeties, who play further back near the center of the field, and who act as the last line of defense. American defensive formations usually includes two of each, a left and right cornerback, as well as a strong safety and a free safety, with the free safety tending to play further back than the strong safety. In Canadian football, which has twelve players on the field co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Secondary Market
The secondary market, also called the aftermarket and follow on public offering, is the financial market in which previously issued financial instruments such as stock, bonds, options, and futures are bought and sold. The initial sale of the security by the issuer to a purchaser, who pays proceeds to the issuer, is the primary market. All sales after the initial sale of the security are sales in the secondary market. Whereas the term primary market refers to the market for new issues of securities, and " market is primary if the proceeds of sales go to the issuer of the securities sold," the secondary market in contrast is the market created by the later trading of such securities. With primary issuances of securities or financial instruments (the primary market), often an underwriter purchases these securities directly from issuers, such as corporations issuing shares in an IPO or private placement. Then the underwriter re-sells the securities to other buyers, in what is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
