Performance Evaluation of Sealed Neutron Tube

Discusses the main specifications,such as neutron yield,operating lifetime,stability,efficiency, anti-shock and anti-vibration of sealed neutron tube. Proposesthe concept of composite quality evaluation.Quality index is used to indicate thequality of neutron tube. Introduces the way of how to define the quality index foreach characteristic of the tube and how to integrate them for composite evaluation.The above method is adaptable to auto-evaluatiqn of the tube.
