The brightness of a linac-based intense positron beam was enhanced for total-reflection high-energy positron diffraction (TRHEPD) measurements. The beam initially guided by a magnetic field was released into a non-magnetic region and followed by a tr

Positronium quenching through its collisions with gaseous atoms and molecules is discussed. It is found that the values of the normalized pick-off quenching parameter, 1Zeff, at room temperature are roughly proportional to the geometric collisional c
