(a) With the aid of a labeled sketch, describe an apparatus for the generation of x-rays. (2 marks) (b) With the aid of labeled sketches, describe the three primary physical mechanisms for the absorption ofx-rays in solids. (2 marks) (c) Make a sketch of a typical x-ray spectrum generated by a hospital apparatus, labeling three primary features of the spectrum (3 marks) (d) For an x-ray apparatus containing a molybdenum target of atomic number, z - 42 (i) What is the wavelength for the shortest characteristic x-ray emission? You may use the relationship for the energy of a quantum state, En- 13.6eV (z-1)2/n2 where is the atomic number of an element, n is the quantum state number where n-1 represents the ground state (2 marks) (ii) Where the accelerating potential is 60 keV, what is the minimum wavelength of emission? (1 mark)
