In this work, an energy-variable positron age-momentum correlation (AMOC) measurement system with a pulsed, 22Na-radioisotope-based beam at AIST was developed for investigating thin materials. Preliminary results for fused silica and polyethylene were obtained using the developed system. The obtained AMOC data agreed well with the previous data for similar bulk samples.
