PVX- 4110
±10,000V PULSE GENERATOR
±10,000V Pulse Output <60ns Rise Fall Times <200ns Pulse Width Optimized drive deflection plates, grids other capacitive loads Protected against arcs, short circuits load transients Voltage Current Monitor Outputs
PVX-4110 pulse generator produces fast, high voltage wave forms 10,000V. Optimized high impedance capacitive loads, PVX-4110 well suited driving extraction grids deflection plates electrostatic modulation particle beams time-of -flight mass spectrometers accelerators. robust versatile design also makes well suited pulsing gating power tube grids, Pockels cells Switches, acoustic transducers, microchannel plates, photomultiplier tubes image intensifiers. exceptional pulse fidelity PVX-4110 will optimize performance system which used. PVX-4110 generates output voltage pulse 10,000 volts with rise fall times less than 60ns, with very flat voltage pulses into capacitive load. generate singled-ended output pulses from ground +10,000V from ground -10,000V, also generate pulses originating from voltage offset from ground using both VLow VHigh power supply inputs. This offset from -10,000V +10,000V, with maximum power supply voltage differential 10,000V. PVX-4110 requires gate signal, high voltage power supply optional offset supply inputs. output pulse width frequency controlled gate signal. pulse output voltage controlled amplitude input power supplies. When input gate high, VHIGH supply connected output. When input gate low, VLOW supply
connected output. Therefore PVX-4110 used generate negative-going pulse logically inverting input gate, that input gate high until unit pulsed. When input gate goes low, VLOW input supply connected output, thereby generating negative-going pulse. PVX-4110 features front panel indicator LEDs monitor status pulse generator. Front panel voltage current monitors provide straightforward means view output voltage current waveforms real-time, eliminating need external high voltage oscilloscope probe. pulse generator direct-coupled, air-cooled solidstate half-bridge (totem pole) design, offering equally fast pulse rise fall times, power dissipation, virtually over-shoot, under-shoot ringing. over-current detection shut-down circuitry protect pulse generator from potential damage arcs shorts load interconnect cable. control protection logic circuitry, support power, energy storage output network incorporated into PVX-4110. connected directly load, does require series shunt resistors, impedance-matching networks between pulser load, additional energy storage (capacitor banks). this taken care within PVX-4110.
