An 11-channel switch tube with 5 stages of electron multiplication was developed. In some applications the switch tube will replace the camera- oscilloscope system for recording the rise times of electrical signals. This tube will be used to convert wide-band information from a single channel into eleven channels of lower bandwidth information which can be transmitted over standard telephone cables for telemetering operations. Venetian-blind dynodes are used for the multiplier structure. Each channel is defined by a pair of louvers on the dynode disk. U-shaped shields which just straddle the louver edge of the preceding dynode, are used to minimize crosstaik. The channel width is 0.120 inch. or a total length of 1.32 inches for the 11 channels. The collector system provides a method for equalizing the gain of ill the channels. The switch tube is 3 inches in diameter and 24 inches in length. Operating at a 4-kv beam potential with 2- mu a beam current, the tube talk to adjacent channels. The electron optics and the performance of the tube are described. (auth)
