Electron sources from STAIB produce an electron beam that can be pulsed to produce sharp power pulses up to the microsecond range. Applications include sample annealing, heat treatment, evaporation, heat shocks, and luminescense studies.

Beam pulsing is available on all focused electron sources offered by STAIB Instruments. Several standard pulsing options are available to cover a wide range of frequencies. Customization is also available to meet the needs of specific experiments, such as additional ranges of pulse widths.

Fast pulsing systems
Pulsing to 100 Hz can be provided as an option to the electron source power supply. For pulsing beyond this frequency, in addition to the electron source and power supply, a pulsing unit plus a special high voltage cable, that provides an input from the pulse unit (a pulse control signal), are needed. The pulsing unit has an internal clock or allows an external TTL pulse signal to give it a reference signal. Several standard pulsing units are available to cover a large range of frequencies. Other ranges of pulse widths are available on request.

Pulsing unit	FP-1	FP-10	FP-100
Minimum pulse length	3 μs	10 μs	100 μs
Maximum pulse length	50 μs	200 μs	20 ms
