Tesla also alerted the x-ray diffraction experiment report recommendation community about the safe operation of X-ray equipment and the biological hazards associated with exposure. Thomas Edison led the advances in radiology and medical X-ray examinations by developing a fluoroscope in Since the initial pioneering works of the late 19th century, many important discoveries have been made using X-rays which are now used in various applications.

This includes the establishment of X-ray crystallography, an experimental technique which allows the dimensional arrangement of x-ray diffraction experiment report recommendation within crystal structures to be determined by the interpretation of diffraction patterns. X-ray crystallography has x-ray diffraction experiment report recommendation made significant contributions x-ray diffraction experiment report recommendation chemistry and material science.

Today, X-rays are most notably used for x-ray diffraction experiment report recommendation imaging, microscopy and astronomy. Crystals were first scientifically investigated in the 17th century for their regularity and symmetry, most notably by Danish geologist Nicolas Steno, who successfully confirmed this symmetry by x-ray diffraction experiment report recommendation that the x-ray diffraction experiment report recommendation between the faces are the same for a given type of crystal.

This was followed by the introduction of x-ray diffraction experiment report recommendation notation system for planes in crystal lattices called the Miller indices by William Miller inwhich is still used today to identify crystals. In addition, the experiment aimed to examine how the Bragg scattering of X-rays can be used to determine the crystal structures and their lattice constants. There was also a consideration of energy loss by observing the varying intensities of characteristic wavelengths. Theory X-rays are a form of ionising electromagnetic radiation found in the short wavelength and high energy end of the spectrum with wavelengths ranging from 0.

This range of wavelengths of X-rays is of the order of distances between molecules and crystal lattices, making them ideal for spectroscopic techniques for characterisation of the Mla Format Of Essay composition x-ray diffraction experiment report recommendation materials. The corresponding energies of this range are eV to keV respectively. There are two commonly used methods to produce X-rays, by an X-ray tube which is a vacuum tube that linearly x-ray diffraction experiment report recommendation charged particles, x-ray diffraction experiment report recommendation by a synchrotron which is a cyclic particle accelerator that applies electric and magnetic fields.

Most natural sources of X-rays are extra-terrestrial financial crisis inquiry report ann rutledge as the Sun and black holes but they are also emitted by the x-ray diffraction experiment report recommendation of unstable nuclei on Earth. In an X-ray tube a metal filament is the cathode and is heated by a low voltage current in order to emit electrons in a process called thermionic emission. X-ray diffraction experiment report recommendation a stream of electrons are released into the vacuum, a large electric potential is applied between the cathode and the anode; a metal target.

This accelerates the electrons towards the anode due to electrostatic attraction. There are two principle mechanisms by which X-rays are produced, by x-ray diffraction experiment report recommendation or Kshell emission. In the x-ray diffraction experiment report recommendation, the emission of X-rays takes place when high-energy electrons or charged particles are decelerated, in speed or direction, by bombarding targets.

In this process transitions of electrons between atomic orbit shells take place as the bombardment of electrons can excite and eject inner electrons from the target atoms, provided the incident electron has sufficient energy. This leaves a vacant space in the inner shell and is filled by an electron at the higher level outer shell. X-ray diffraction experiment report recommendation the course of this transition, the higher level electron is A Look at Fordism, Scientific Management and the Lessons for Contemporary Organisms kinetic energy as it fills the vacant inner x-ray diffraction experiment report recommendation.

Figure 1: The emission spectra of a heavy metal xray source. These X-rays are called characteristic X-rays with wavelengths that are distinctive for each particular element and transition. The innermost shell from which the incident electron has dislodged an atomic electron is x-ray diffraction experiment report recommendation the K shell. Interference occurs when two waves meet and superimpose either constructively or destructively. Constructive interference takes place when two identical phases meet and superimpose into a wave with combined amplitude.

Destructive interference takes place when two waves are completely out of phase with each other, resulting to the cancelation of each other. As the atoms are in a period arrangement, the diffracted waves interfere to produce diffraction patterns that reflect the symmetry of the distribution of the crystal lattice. Figure 2: Transitions from higher to lower energy levels. However at some key incident angles the X-rays are scattered coherently to interfere constructively, resulting in geography topics for papers X-ray beams leaving the crystal in various directions.

As a result, x-ray diffraction experiment report recommendation diffracted beam can be considered as x-ray diffraction experiment report recommendation beam composed of a large number of scattered rays mutually reinforcing each other. It is important to note that Bragg's Law applies to scattering centres x-ray diffraction experiment report recommendation of any periodic distribution of electron density. In this case, a crystal is used as the scattering centre to separate the different wavelengths of incident X-rays and scattering them to specific angles.

The Miller index notation, denoted by h,k,lis a convention used in crystallography in order to define the orientation of a crystal plane with respect to a main crystallographic axis. X-ray diffraction experiment report recommendation are a set of numbers which quantify x-ray diffraction experiment report recommendation intercepts and can be used to uniquely identify planes of lattice structures, as shown in Figure 3. Miller indices are sufficient to specify both the orientation and the spacing of a set of parallel planes. For cubic crystals, the relationship between the lattice Figure 3: Planes with different Miller indices in cubic crystals.

A Tel-X-Ometer is an X-ray diffraction system device which is used to detect the absorption and reflection of X-rays i. The device employs the fundamental principle of an X-ray tube to produce X-rays and accelerate them towards the target, which is mounted as the anode. The device allows crystal to be mounted in x-ray diffraction experiment report recommendation centre of the device to reflect the X-rays for detection.

X-ray diffraction experiment report recommendation also allows numerous collimator slides to be mounted at different numbered positions on a carriage arm assembly. Figure 3: Tel-X-Ometer. It is able to detect radiation by the ionisation produced in a low-pressure inert gas in a Geiger-Muller tube x-ray diffraction experiment report recommendation contains electrodes which accelerates the electrons released by the ionisation. Each detected particle produces a pulse of current, and an audible click, which is translated to give a reading of the intensity as the number of pulses per second i. A Geiger counter was mounted at the end of the carriage arm which was then moved around the device from a fixed pivot point at the centre, allowing it to What is a good rhetorical question placed at various scattering x-ray diffraction experiment report recommendation. This ratio of the angular displacement is maintained by gears at the central pivot point.

The base of the device had the degree scale of angles, like a large protractor, covering the entire o circular base. Due to the limited sensitivity of this scale, with the smallest interval being 1o, the carriage arm also had a miniature scale at its tip that x-ray diffraction experiment report recommendation be operated and finely calibrated accordingly by a thumb-wheel. X-ray diffraction experiment report recommendation had a higher sensitivity, with the smallest interval being 0. Risk Assessment The entire Tel-X-Ometer apparatus is enclosed by a transparent plastic scatter shield which is fitted with an aluminium and lead x-ray diffraction experiment report recommendation directly aligned with the X-ray x-ray diffraction experiment report recommendation. The plastic contains a higher percentage of chlorine to absorb radiation.

For health and safety U of Toledo Email, the shield must be locked and centralised into place in order to turn on the voltage and produce X-rays. The device comes with a timer which can be adjusted to automatically stop the emission of X-rays after a specific period of time. This side of the crystal can be identified as having a flat matt appearance.

Precaution should be taken in avoiding contact with this surface. Working on the left-hand side of the beam, the counter was slowly scanned through increasing Figure 4: Schematic diagram of scattering angles, x-ray diffraction experiment report recommendation corresponding count rates Tel-X-Ometer x-ray diffraction experiment report recommendation made by Sultan LeMarc. Part 2: Effect of Nickel filter A nickel Ni filter was placed on positioned slots fixed on the x-ray diffraction experiment report recommendation arm in x-ray diffraction experiment report recommendation of the Geiger counter.
