Abstract: Apparatus for the production of a charged particle beam, comprising: an ion source plasma chamber (104), having a door (106), and an accelerator (102) mounted on the face of the door remote from the ion source plasma chamber.

Abstract: A flash strobe power supply adapted for controlling alternately the energization of a pair of flash lamps includes a trigger timing device for generating a series of positive pulses and a series of negative pulses spaced in time from the positive pulses by a predetermined interval. First and second energy storage devices are provided for repeatedly charging incrementally during successive charging cycles and for storing a charge to be applied to respective first and second flash lamps. An inverter oscillator circuit includes a pulse width modulator and a transformer for generating a quasi-squarewave signal whose frequency is greater than the frequency of the positive and negative pulses to control the incremental charging of the energy storage devices. First and second switching devices deliver when conductive the charge stored in the first and second energy storage devices to their respective first and second flash lamps.

Abstract: A high frequency fluorescent lamp circuit for operating two or more fluorescent lamps connected in electrical series. A capacitor is connected between one end of the series-connected lamps and electrical ground and/or an electrically conductive fixture for holding the lamps. This causes the lamps to start more reliably and at a lower starting voltage.
