Current Research in the Positron Annihilation Spectroscopy Lab at TCU

Positron Annihilation Spectroscopy (PAS) is a nano-scale experimental technique that can help us investigate the defects,voids and free volume in a wide varitety of materials such as polymers and polymer composites, polymer films, nanoparticles, pure metals and alloys, semiconductors, Zinc Oxide, Copper Oxide, and biological samples such as normal and tumor tissue.

Positron annihilation spectroscopy


To the student looking for a research project. . .

There are some very interesting research problems which are suitable for study using PAS. I would be happy to discuss a senior research project or a Junior/Senior Honors research project with you. Just send me an email to make an appointment to discuss the research. Funding is also sometimes available (2009 and 2010) for a qualified student to work on research during the summer.

There are some very useful and important skills to be learned in PAS research which have very practical applications in industry. Mastering the skills involved in this research may help you get a better job when you graduate.

If you decide to work on a research project in the PAS lab, you will have to become an expert in the techniques of positron annihilation spectroscopy. This includes learning how to use data acquisition and analysis software, x-ray and particle detectors, energy dispersive x-ray and gamma ray spectroscopy, modular electronics systems such as NIM and CAMAC, and time-coincidence techniques. You may also get experience with vacuum systems or need to master a variety of computer languages and systems, get involved with some computer interfacing, or do some computer modeling. You will work with x-rays, gamma rays and radioactive sources. But you will learn how to work safely with radiation so that you can concentrate on the physics!
