F100 - Fast Digital Electrometer

The F100 measures currents from nA to mA from an external detector. For example Faraday cups, ion chambers, beam position monitors, or photodiodes.

The primary application is real-time dosimetry for proton therapy. The F100 integrates current into a total charge. It generates a monitor pulse for each defined aliquot of total charge. After the total charge reaches a predetermined target its digital logic output triggers. This digital output connects up to a beam command or pneumatic actuator. The unit could be stand-alone or integrated into a larger control system.

The F100 can use an auxiliary high-voltage output up to 2kV. The source is suitable for electrical suppression of secondary electrons in Faraday cups like the BC-75.

Fiber Optics

Measurement data is transmitted through state-of-the-art fiber-optic cables. The benefits are numerous compared to other forms of data transmission.

  • Fiber-optics are immune to electrical interference
  • Minimal attenuation of light through fibers
  • Fast messaging over enormous distances
  • Radiation hard fiber materials
