Improvement of Positron Annihilation Lifetime Spectrometer Resolution: A Comparative Study
Positron life time spectroscopy (PALS) is a variant of positron annihilation spectroscopy (PAS), which is of great interest to researchers for a wide range of applications such as medical sciences: Molecular imaging by positron emission tomography1, tumors2, as it can also provide a plus regarding the harmfulness of a new drug3, or biology4. It is also used in astrophysics5, development and manufacturing of telecommunication equipments6 for high reliability critical service applications. The objective of my work is to improve the PALS coincidence system, to have a better instrumental (temporal) resolution combined with a high count rate. For this purpose, we opted for a FAST-FAST system.
