Therac-25 had two modes of operation: • Direct electron-beam therapy - a low power electron beam is directly administered (5 MeV - 25 MeV) • Megavolt X-Ray therapy - the high-energy electron beam is converted to an X-Ray beam by colliding the electron beam into a so-called ‚‚target“. The target consists of a filter‚ which expanded the beam over a certain area‚ a so-called collimator to shape the X-Ray beam and a device to measure the strength of the beam. Figure 1: Sketch of the two modes of operation

Timber can be utilized and designed to fit nearly any project‚ one such example would be forming the project into the traditional look of a solid sawn timber structure from days of old. While the engineered laminate beams are taking designs into a new realm‚ such as offering new levels such as curved and other

consists of a pair of cuved timbers which are known as the cruck blades‚ these are often cut from the same tree by cutting right down the middle of the trunk‚ this means that whatever the shape (twist/bend) the pair will be identical. A collar/tie beam would sometimes be added in order to brace the frame and to stop it from bending/twisting. The cruck frame is the key element in cruck construction as the frame carries the whole load directly to the ground. “This type of construction continued until

use the light ray box to direct the incident light beam to the air-block boundary at an angle with respect to the normal. Observe the direction of the transmitted beam inside the block and the emerging beam at the block-air boundary. Next‚ use a ruler to draw a line to coincide with the path of the incident light beam. This is the direction of the incident ray. After that‚ use a ruler to draw a line to coincide with the path of the emerging light beam. This line represents the direction of the emerging

and SO3. When these gases react with atmospheric water‚ they turn into sulfuric and nitric acids such as H2SO4 or HNO3‚ eventually spilling back to earth as toxic acid rains. But when these oxides are mixed with ammonia (NH3) and exposed to electron beams‚ they can be turned into ammonium sulfate and ammonium nitrate‚ common fertilizers. The reaction creates dust-like particles that could be gathered with an electrostatic or centrifugal particle separator and put on the field. Kephart sees the idea

Hypothesis: It’s crucial to predict the outcome of the experiment and provide a hypothesis. A hypothesis allows the researchers to think about their prediction in relation to the experiment’s outcome. In this case‚ I had a few hypothesis and predictions on this experiment. First off‚ refraction is the bending of light when it travels through different medium. Therefore‚ the light will bend and it will shift away from the original location. However‚ I don’t know where the shift will be‚ but according

cathode ray is a beam of electrons which are emitted by the heated cathode (negative electrode) and accelerated toward the fluorescent screen. The assembly of the cathode‚ intensity grid‚ focus grid‚ and accelerating anode (positive electrode) is called an electron gun. Its purpose is to generate the electron beam and control its intensity and focus. Between the electron gun and the fluorescent screen are two pair of metal plates - one oriented to provide horizontal deflection of the beam and one pair

FREE SPACE OPTICS Free space optics or FSO‚ free space photonics or optical wireless‚ refers to the transmission of modulated visible or infrared beams through the atmosphere to obtain optical communication. FSO systems can function over distances of several kilometers. FSO is a line-of-sight technology‚ which enables optical transmission up to 2.5 Gbps of data‚ voice and video communications‚

Another example of this may be given. Focusing a very high energy laser beam on a piece of metal can actually melt the metal. Equipment using high energy lasers are used in industry to accurately cut and weld sheets of metal. As for surveying‚ everyone
