ISUAL HIGH VOLTAGE SUPPLIES
P.BERG
CDR 9 JULY 2001 2NCKU UCB Tohoku High Voltage Supplies P. Berg
HIGH VOLTAGE P0WER SYSTEM OVERVIEW
•HIGH VOLTAGE IS REQUIRED ON ISUAL TO SUPPLY THE PHOTOMETER, THE IMAGER MICRO CHANNEL PLATE DETECTOR, AND THE IMAGE PHOSPHER
•THE HIGH VOLTAGE POWER SUPPLIES ARE DESIGNED TO OPERATE AT
AMBIENT PRESSURE OR UNDER VACUUM ( MINIMUM 2HR PUMPDOWN)
•HIGH VOLTAGE DISTRIBUTION IS ACCOMPLISHED USING CUSTOM UCB CONNECTORS AND PLUG-IN INTERFACES, AVOIDING CABLES

SPECTROPHOTOMETER HIGH VOLTAGE SUPPLIES
• DESIGN BASED ON SUPPLIES FLOWN ON EUVE, FAST, AND IMAGE FUV– TWO TRANSISTOR PUSH-PULL COLPITTS OSCILLATOR DRIVES COCKCROFT-WALTON STACK– CIRCUIT INCLUDES VOLTAGE AND CURRENT MONITORS AND OVER CURRENT LIMITING
• MULTIPLIER STACKS BASED ON CW CARLSON DESIGN– COMPACT IMPLEMENTATION WITH VERY GOOD CONTROL OF E-FIELDS AND SURFACE
BREAKDOWN PATHS
• HVPS HEAT CONDUCTED TO SIDEWALLS AND THEN TO BASE
• PROGRAMMABLE TO FULL OUTPUT VOLTAGE WITH 0 TO 5 VOLT INPUT
• CAN DELIVER 100 uA
• QUIET OUTPUT - <1MV UNLOADED NOISE
• POUR POTTED TO SAVE WEIGHT
• SERIES OUTPUT RESISTOR TO ABSORB BRIEF SHORTS
• OPERATE FROM SINGLE +12 VOLT SUPPLY
• THERMISTOR TEMPERATURE MONITOR
