The HMPS series of sub-nanosecond pulse generators allows very high voltage, fast rising pulses to be obtained from a compact bench top unit. Low jitter means that multiple units may be used to drive synchronized loads such as deflection plates, or be combined to drive low-impedances. This aspect makes the pulsers particularly useful for driving microchannel plate systems.

This pulser can feed into a short circuit load without damage. This allows it to be used in sub-nanosecond pulse chopping systems by feeding through a pockels cell into a shorting stub.

This unit requires AC power and a trigger signal to operate. The trigger signal, which is applied to the trigger input (BNC), should be approximately 10 V with a fast rising edge of <5 ns to achieve the lowest possible jitter. When triggered, the "triggered" light on the front panel will flash.

The main output of the unit appears at the front panel connector (BNC). If it is necessary to monitor or characterize this pulse, suitable attenuators should be used. Kentech recommends the use of a high voltage, high speed attenuator manufactured by Barth as the first attenuator in a series. The high voltage pulse from this unit is capable of destroying many lower power attenuators, including GR types. The output may be characterized using a >3 GHz bandwidth oscilloscope.

If the output of the HMPS pulser is to be used directly or via any passive network it is essential that cable lengths are kept as short as possible and that only high quality cable is used. This will enable the fast rising edge generated by the unit to reach the load without serious degradation.
