The PVM-4210 is a compact, OEM-style pulse generator module providing two simultaneous differential voltage pulses. It is optimized for differential drive of deflection plates for electrostatic modulation of particle beams in time-of-flight mass spectrometers and accelerators.
The PVM-4210 is a complete pulser solution with high voltage power supplies, energy storage and output network. The module includes two pulse output channels that are controlled by a common control logic. Each channel is a half-bridge (totem pole) design, offering equally fast pulse rise and fall times, low power dissipation, and virtually no overshoot.
The block diagram on the page below shows the main functional blocks of the pulser:

The PVM-4210 is optimized for differential drive of deflection plates for electrostatic modulation of particle beams in time-of-flight mass spectrometers and accelerators. It will also drive any high impedance, capacitive load such as Pockels Cells and Q Switches, electrodes, microchannel plates, acoustic transducers, image intensifiers and photomultiplier tubes. The exceptional fidelity of the PVM-4210 will optimize the performance of any system which it is used |
