Aims |
|
To give a practical and theoretical knowledge of gamma ray detection using scintillation, semiconductor and gas detectors to use a modelling code to predict detector performance. |
Learning Outcomes |

(LO1) Knowledge of the interaction of gamma-rays with materials |
|
(LO2) Knowledge of scintillation and semiconductor detectors (construction and uses) |
|
(LO3) The ability to set up and use scintillation and semiconductor detectors |
|
(LO4) The ability to use the MCNP code to model detector performance |
Syllabus |
|
Interaction of gamma rays with material (solid and gas); photoelectric effect, Compton scattering, pair production. Scintillation pricniples, types of scintillator, scintillation mechanisms, organic molecules, fluorescence and phosphorescence, quenching, inorganic scintillators, band structure and activators. Types and properties of organic and inorganic scintillators. Light collection and photoelectron production. Photomultiplier tubes; basic elements, photocathodes, electron multiplication. Spectroscopy with scintillators. Properties of spectrometers including resolution, linearity, gain stability and efficiency. Arrays of scintillation detectors, whole body, PET and CAT scanners. Semiconductor detectors; types of semiconductor (silicon, germanium, cadmium telluride, cadmium zinc telluride etc). Different types of detector geometry; planar, coaxial. High resolution spectroscopy for X-rays and gamma-rays. Use of the MCNP code to model various situations involving gamma ray detectio n. |
