Construction of a complete pneumatic transport system (PTS) for automatic Activation analysis The International Atomic Energy Authority (IAEA) requested that an economic and complete pneumatic transfer system (PTS) for short-time activation analysis be developed and fabricated. The system will be implemented in a new nuclear analytical laboratory, which will be established by IAEA in Vietnam. A software package, a control unit and irradiation capsules will be developed and fabricated to facilitate optimal automatic irradiation-measurement procedures. Additionally, 11 essential units and chambers will also be constructed in order to guarantee efficient and fully-automatic analysis.
