Abstract:
Positron Annihilation Spectroscopy (PAS) is a spectroscopic technique that
makes use of positrons impinging on a material sample to perform ultra-
sensitive spectroscopic measurement of the defect concentration (and types)
and chemical environment in a material.

If this talk we will present the basic methodology behind PAS, as well as de-
scribe the SPOT-IL positron facility at the Hebrew University, which consists
of two independent and complimentary measurement setups. We will further describe our 
advances in graphene-based positron charge sensors, and their potential in 
probing positron transport. We will outline our vision for future applications 
of PAS-based local probes.
