PUL 03

The PUL 03 is a 10 nanosecond, 400 volt pulser, primarily designed for use with Ionoptika ion beam systems to provide a fast pulsed beam. However, it may also be used with other systems that have suitable termination.

Description

The PUL 03 comprises a control box, a 24 V dc power supply and an amplifier that connects directly to the ion column feedthrough . The pulser is controlled by means of a touch pad on the top of the unit. Mode of operation, voltage, and pulse width are selectable. It is designed to drive an open circuit load of 4 to 10 pF capacitance. It is not intended to run into any resistive load or short circuit of less then 10 Mohm.
The Pulser has 4 modes of operation:


1. Volts to Ground Mode

This is the main mode of operation – the pulser output normally sits at the set voltage (set between 10 V and 400 V). When triggered, the output drops to zero for the set duration, then returns to the set voltage. It requires a trigger pulse of 0 to 5 volts, remaining at 5 volts for longer then the duration of the output pulse. It also needs to be at the set voltage for a minimum of 100 nsec prior to the rising edge that it triggers on. The minimum pulse width is about 10 nsec.


2. Ground to Volts Mode

The second mode of operation is with the pulser output at ground, pulsing to the set voltage when triggered then back to ground after the set time. Note that this mode has a minimum pulse width of about 100 nsec.


3. Follow Mode

This sets the output high when the input is high, and low when it is low (or this can be inverted).


4. Internal Clock Mode
This allows you to set a frequency for it to run at – e.g. 10 kHz – and it will then run at that speed, with pulses as set by mode 1 or 2. There is a maximum frequency of 10kHz.

Connections

The PUL 03 has a separate 24 V dc psu, that runs from a universal mains input. This connects to the control unit in the socket on the right hand side of the box.
There is a BNC trigger input. This requires a 0 to 5 volt pulse, of duration longer than the required output pulse. The output pulse occurs 194 ns after the trigger. The trigger pulse needs to be able to drive a 50 ohm load.
There is a circular 5 pin connector that connects the control unit to the head amplifier via a 1m cable, on the left hand side of the control unit.
There is a separate head amplifier with a BNC connection that is connected directly to the BNC vacuum feedthrough. Note that this unit is intended to drive an open circuit, and must not be used to drive a load of less then 10Mohm.
