October 2017 – IXYS 2000V Pulse Generator for Time-of-Flight Mass Spectrometer & Accelerator Apps

Published on: 03/10/2017

Earlier this year IXYS announced the introduction of the PVX-4000-2kV Bipolar 2000V Pulse Generator by its IXYS Colorado division

IXYS PVX-4000-2kV, 2000V Pulse Generator


2000V Pulse Generator

The PVX-4000-2kV is an air cooled, high voltage pulse generator optimised for high impedance, capacitive loads. The pulse generator is well suited for driving extraction grids and deflection plates for electrostatic modulation of particle beams in time-of-flight mass spectrometers and accelerators and other scientific applications requiring precision high voltage pulses.

It features a robust and versatile design which make sit well suited for pulsing or gating power tube grids, pockels cells and Q switches, acoustic transducers, microchannel plates, photomultiplier tubes and image intensifiers.

The output voltage can be set from 0 Volts to Bipolar 2000 Volts with pulse rise and fall times of 50 nanoseconds. It provides pulse widths from 500 ns to DC, with duty cycles from 2% to 100% and repetition rates from single-shot to 30,000 Hz. With a built-in trigger source and internal positive and negative high-voltage DC power supplies, the PVX-4000-2kV can be used as a standalone test system.

Manual instrument control is achieved through a front panel interface. For automated applications, complete control of the instrument is provided through RS-232 and USB computer interfaces. Up to five system configurations can be stored in the internal non-volatile memory, providing instant recall of frequently-used configurations.

The front panel BNC connectors are conveniently located to allow the PVX-4000-2Kv to be externally triggered. It also has a sync output, synchronised 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.

Stephen Krausse, General Manager of IXYS Colorado commented on the launch,

“The PVX-4000-2kV builds upon the successful design of our field-qualified PVX-4100 series pulse generators by incorporating an integrated microprocessor controller and DC power supplies to offer an easy to use, standalone system. Furthermore, it leverages the advanced device technology of our parent company, IXYS Corporation to achieve new levels of reliability and cost effectiveness.”

The PVX-4000-2Kv is available directly from GD Rectifiers, IXYS’ Official UK Distributors.
