The Aladdin Frequency Accelerating System Power Amplifier: 140 KW at Considerably Less than a Dollar a Watt

Modern gridded power tubes offer enormous power gain and thus make possible very economical high power radio frequency systems provided that the often troublesome problems of stability can be solved. We have developed a grounded cathode 50 Mhz, 140 KW power amplifier that achieves a power gain of over 30 db to provide radio frequency power for the electron storage ring Aladdin. Because of the low drive power requirements and the simplicity of the mechanical and electrical design, the cost of this power amplifier, including development, was less than $100,000.
