High voltage pulse generator targets scientific and R&D instruments
The PVX-4000-2kV-EX is aimed at driving extraction grids and deflection plates for electrostatic modulation of particle beams in time-of-flight mass spectrometers and accelerators. The design also makes it well suited for pulsing or gating power tube grids, Pockels cells and Q Switches, acoustic transducers, microchannel plates, photomultiplier tubes, image intensifiers and high voltage testers.

To provide users with increased system design flexibility, the DC high voltage for the pulse generator comes from an external, user-provided, high voltage DC power supply. Using the external supplies, the output voltage can be set from 0 V to +/-2000 V. Duty cycles from 2% to 98% and repetition rates from 40 Hz to 30,000 Hz are supported by the internal trigger source. Pulse widths from 500 ns to 100% duty cycle and repetition rates from single-shot to 600 kHz are supported when an external trigger source is used.
For automated applications, complete control of the instrument is provided through RS-232 and USB computer interfaces. Up to five system configurations may be stored in internal non-volatile memory, providing instant recall of frequently-used configurations.
Front panel connectors allow the PVX-4000-2kV-EX to be externally triggered and it has a Sync output, synchronized to the leading edge of the output voltage pulse, for interconnection to other equipment. The output pulse waveform can easily be monitored through the Voltage Monitor BNC connection using an oscilloscope.
“The PVX-4000-2kV-EX expands on the capabilities of the PVX-4000-2kV,” said Stephen Krausse, General Manager of IXYS Colorado. “Providing the option for external DC power supplies provides more flexibility in system design, and a higher power capability, than the PVX-4000-2kV model. The performance of this pulse generator is enabled by IXYS’ unique power drivers.”
