Directed Energy, Inc (DEI) provides information on its products and associated hazards, but it assumes no responsibility for the after-sale operation and safety practices. ALL PERSONNEL WHO WORK WITH OR ARE EXPOSED TO THIS EQUIPMENT MUST TAKE PRECAUTIONS TO PROTECT THEMSELVES AGAINST POSSIBLE SERIOUS AND/OR FATAL BODILY INJURY. Document Number 9100-0201 Rev 8 © Directed Energy, Inc. 2000-2002 Page 2 DEI PVM-4210 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 Document Number 9100-0201 Rev 8 © Directed Energy, Inc. 2000-2002 Page 3 DEI PVM-4210 photomultiplier tubes. The exceptional pulse fidelity of the PVM-4210 will optimize the performance of any system in which it is used. The module provides two pulse output channels, controlled by a common control logic. When the control logic receives a gate signal, both channels pulse simultaneously. One channel pulses from groun...
