Deuterium Lamp Filament Control
Before ignition, the deuterium lamp filament control circuit provides a constant voltage
of 2.5 VDC at approximately 6 A to the filament of the deuterium lamp. The deuterium
lamp filament control circuit is enabled by the processor on the DAM board.
Deuterium Lamp Current Control
The deuterium lamp current control circuit comprises two parts. One part generates an
ignition pulse of 600 VDC for the lamp, resulting in lamp ignition. After ignition this
voltage is disabled. The other part is a constant current source of 320 mA at an
operating voltage of about 85 VDC for stable operating conditions and light emission of
