THE ELECTRICAL SYSTEM OF THE BEVATRON RAPID BEAM EJECTOR (BEAM-KICKER)

Description: The operation cycle of a bubble chamber includes a brief period during which charged particles entering a chamber produce optimum tracks. Following the lead of Rahm at the Brookhaven Cosmotron, a group at the Berkeley Bevatron constructed a rapid beam ejector to produce brief pulses of particles. Energy stored in a capacitor bank is transferred to an air-core magnet suarrounding the proton beam of the Bevatron. The protons are displaced from their normal orbit and strike a suitably located targ… more

NOTES ON THE DESIGN OF FLOW DISCHARGE VOLTAGE STABILIZERS FOR PHOTOMULTIPLIER TUBE POWER SUPPLIES

Description: A series of high-stability neon glow discharge tubes (OG3/85A2) was used to stabilize 1685 volts for the dynode resistance divider of a photomultiplier tube to an accuracy of plus or minus 0.2%. The limit of stability and the aging phenomena for the tube operating at reduced currents are discussed but not understood. (auth)

BEVATRON OPERATION AND DEVELOPMENT. XIII. Period covered February, March, April 1957

Description: During this entire quarter, the Bevatron was shut down for major rework of the magnet-coil air shroud and for the scheduled construction of a new experimental area at the north straight section. The existing west and northwest experimental areas were also improved. The Bevatron motor-generator sets and associated ignitrons were overhauled. At the end of this period, the magnet coil rework is concluded and the scheduled shutdown work is well advanced. (auth)

A GENERATOR OF FAST-RISING LIGHT PULSES FOR PHOTOTUBE TESTING

Description: The UCRL light-pulse generator provides flashes of light accompanied by electrical pulses generated at an impedance level of 50 ohms. The usual repetition rate is 60 cps. The 10 to 90% rise, both for the light and for the electrical pulse, is less than 0.5 m mu sec. The light pulse rises and then falls to 50% peak amplitude in less than 1.5 m mu sec. The time relation between the light and electrical pulses is fixed. The electrical pulse power available is large. In conjunction with an oscillos… more

TUBE DESIGN AND CIRCUIT CONSIDERATIONS FOR FAST-HEATING ELECTRONIC SYSTEMS

Description: Fast-heating electronic systems are becoming increasingly important in military applications. Operational requirements in the range of 10 to 12 seconds must be accomplished with a combination of tube and circuit design. Definitions of tube and system operational time are numerous and interrelated so that selection of an appropriate test depends on the circuit application, ease of measurement, and test equipment capabilities. Circuit designs which minimize differences among tubes will also minim… more
