Beam-Beam Effect

Recently, beam effects and beam interactions are being studied in many parts of the world from European laboratories to American laboratories. Basically this problem involves many different types of effects, including accidents, due to proton beams. In addition to cross-firing of particles, the collision rate of protons usually produces a certain amount of energy. Today's problem is to concentrate on fixing new colliders to improve machine efficiency.

Raman effect, change in the wavelength of light generated when the beam is deflected by molecules. When a light beam passes through a transparent composite sample without dust, only a small part of light emerges in a direction different from the incident (incident) ray. Most of the scattered light has a constant wavelength. However, a small part of the wavelength is different from the wavelength of the incident light, and its presence is the result of the Raman effect. This phenomenon was named after Indian physicist Chandrasekhara Venkata Sir Raman who first announced observation of this effect in 1928. Austrian physicist Adolf Smekal theoretically described this effect in 1923. It was first observed by Russian physicist Leonid Mandelstam and Grigory a week before Raman. Landsberg; however, they did not publish their results in the months following Raman. )

Beams are structural elements that mainly resist the loads applied transversely on the axis of the beam. The deflection mode is mainly curved. A reaction force is generated at the beam fulcrum due to the load applied to the beam. The total effect of all the forces acting on the beam is the occurrence of the shear moment and bending moment in the beam. This will cause internal stress, strain, and deflection of the beam. Beams are characterized by their supporting method, profile (shape of cross section), length, and their material.

Bending of the beam also affects the shape and effect of the beam. When the beam is actively bent, the beam bends downward, and pressure is applied to the cross section of the lower part of the beam. This is called "slack". However, a negative bend bends the beam upwards and applies more pressure to the upper section of the beam; this is called "hogging". Both of these can distort the beam and make the beam unsuitable for its use. There are many materials available in the building. Different materials have different objectives and are suitable for preventing occurrence of specific things in the structure and aesthetic of the building. The three most commonly used materials as building materials are as follows. Wood, plastic and metal

Engineeringly, the beam was originally a hard piece of wood, such as a beam, a plow, a loom, a house balance. In the structure of the building, the beam is a horizontal member that supports the load across the opening and may be a brick or stone wall above the opening. The load can be on the floor or roof in the building. In that case, the beam is called a floor beam or a roof beam. In the deck, lightweight stringers are longitudinal members, heavier lateral members are called floor beams.
