FIELD: electron and X-ray sources for radiation physics and chemistry, etc. SUBSTANCE: novelty in flash tube that has evacuated envelope and insulator-mounted explosive-emission cathode with electron emitters on current-conducting base is that electron emitters are made in the form of identical laminated projections by their incomplete cutting and bending from base material. Laminated projections may be of triangular, semi-circular, or trapezoidal shape. EFFECT: enlarged area of uniform spot, extended service period, simplified design of tube. 2 cl, 4 dwg
