A body cavity search is either a visual search or a manual internal inspection of body cavities for prohibited materials (contraband), such as illegal drugs, money, jewelry, or weapons.Body cavities used for concealment include nostrils, ears, mouth, navel, penis (urethra and foreskin) or vagina, and rectum.n a thorough visual body cavity search, a flashlight is used to illuminate body orifices, including nostrils, ears, mouth, navel, penis (urethra and foreskin) or vagina, and rectum. Generally, the detainee is required to manipulate these body parts so that they can be examined.
A radiofrequency (RF) cavity is a metallic chamber that contains an electromagnetic field. Its primary purpose is to accelerate charged particles.RF cavities can be structured like beads on a string, where the beads are the cavities and the string is the beam pipe of a particle accelerator, through which particles travel in a vacuum.igh-power klystrons (tubes containing electron beams) drive each RF cavity on the LHC. A high-power electron beam inside the klystron modulates at 400 MHz. Power is extracted through a rectangular pipe of conducting metal called a waveguide, which leads to the RF cavity.
