Content:

  • Fluorescent/phosphorescent decay time: use of an optical setup with a pulsed laser to excite a variety of fluorescent and/or phosphorescent materials in order to determine characteristic decay times. The time dependent information is obtained via the use of boxcar integrator electronics.
  • Gamma ray Spectroscopy: use of an ultra-pure Ge detector at low temperature for measurements of gamma ray spectra. Use of specialised pulse amplification and conditioning electronics.
  • Non-ionising Radiation: use of a spectrum analyser for the analysis of electromagnetic signals ranging in frequency from 10 Hz to 10 GHz.
  • Photothermal radiometry: Measurement of photoinduced thermal response. Use of cryogen cooled infrared photodetector and acousto-optically modulated photoexcitation in combination with a lock-in technique.
  • Paramagnetic Resonance: Measurement of the gyromagnetic ratio of the electron using an electron spin resonance experiment and lock-in techniques.

Assesment

1. Lab report:
• Lab reports are required for each of the experiments from each student.
• The grade average of the reports of all the lab exercises contributes to the final grade of the course.

2. Final Presentation
• Each student carry out an 30 min presentation of one of the experiments of their choice.
