Design for X-ray source strength on intermediate ballisties velocity meter

Tube-current & voltage are the important parameter of the X-ray source, these directly affect the measurement accuracy of the intermediate ballistic velocity meter based on X-ray. This paper analyses systematically the determination method of the minimum tube current and tube voltage for X-ray in the precondition of satisfying the measurement precision and the minimum radiation protection. The experiments have proved that the analytic method is feasible. For related dynamic detection simplify the whole system of radiation protection designed to reduce cost have guiding significance.
