The Full Form of PSST is‍ Plasma Sources Science and Technology.

Plasma Sources Science and Technology (PSST) reports on low-temperature plasmas and ionized gases operating over all ranges of gas pressure and plasma density, with varying degrees of ionization. The emphasis of PSST is on the fundamental science of these plasmas, their sources and the physical and chemical processes initiated or sustained by them, as elucidated through theoretical, computational or experimental techniques. PSST also reports on new experimentally or theoretically derived fundamental data (e.g. cross sections, transport coefficients) required for investigation of low temperature plasmas. Reports that relate to the technology and applications of these plasmas should be closely linked to the science and fundamental processes occurring in the plasma state.
