1.0 Safety
The high voltage/high current nature of this device dictates the use of
caution when operating or servicing this equipment. OBSERVE ALL
SAFETY PRECAUTIONS LISTED BELOW. FAILURE TO DO SO COULD
RESULT IN SERIOUS INJURY.
Precautions:
1. The Pulser should be serviced only by personnel experienced in high
voltage pulsed power systems.
2. Service personnel should be instructed to observe all safety precautions
as stated in the operating instructions, and those safety precautions
standard to the high voltage pulsed power community. Failure to do so
could result in serious injury.
3. Do not handle the load or terminations, or remove the input or output
cables, while the driver is in operation. Ensure that the high voltage
power supplies have fully discharged before handling the load. Failure to
observe these precautions can result in potential electric shock to
personnel, arcing, and damage to the connectors and system.
4. The Pulser contains reference planes which are elevated to the potential
of the output pulse. Extreme caution should be exercised when servicing
the equipment.
5. Pulsed power systems are capable of random triggering via transients
and therefore when the driver is turned on, or high voltage is present in
the module, assume it is possible to get a pulse on the output cable.
2.0 Overview
The PVM-4210 is a compact, OEM-style pulse generator module providing
two simultaneous differential voltage pulses of up to
± 950V (1,900V
differential), with pulse rise and fall times <15 nanoseconds, and pulse
widths continuously adjustable from <40 nanoseconds to DC. The pulser
operates on +24VDC to +28VDC support power, and features integrated
DC high voltage power supplies.
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
