Proton TherapyCurrent Measurement

Downloads

The FX4 is a sophisticated 100 kHz, 4-channel electrometer, designed to accommodate nanoamp to milliamp currents, making it an ideal choice for precise and reliable measurements in conjunction with quadrant or segmented detectors. Equipped with an integrated high-voltage source, the FX4 facilitates compatibility with ionization chamber, low-voltage bias applications, and electron suppression rings, ensuring versatility in various experimental setups.

One of the key strengths of the FX4 is its ability to function as four separate electrometer channels, providing users with the flexibility to customize the device for their specific requirements. This adaptability optimizes both efficiency and accuracy, resulting in enhanced performance across diverse applications.

In addition, the FX4 boasts an extensive dynamic range, enabling the measurement of low currents from devices such as the BC-75 Faraday collector. This comprehensive range ensures the FX4's applicability in various fields, including Flash therapy and ultra-high dose rate measurements.
