A high dynamic range data acquisition system for a solid-state electron electric dipole moment experiment.

Area of Science:

• Experimental Physics
• Particle Physics
• Metrology

Background:

• Precise measurements of fundamental particle properties, like the electron electric dipole moment (EDM), are crucial for testing the Standard Model and searching for new physics.
• Existing data acquisition systems may suffer from noise and ground loops, limiting measurement precision.

Purpose of the Study:

• To design and implement a high-precision, 24-bit data acquisition (DAQ) system for electron EDM experiments.
• To achieve galvanic isolation between components to minimize noise and cross-talk.

Main Methods:

• Development of a custom DAQ system with a master control board and eight individual analog-to-digital converter (ADC) boards.
• Implementation of fiber optic communication for galvanic isolation between the master board and ADC boards.
• Simultaneous sampling of eight input channels for high-throughput data collection.

Main Results:

• The custom DAQ system achieves 24-bit precision.
• Galvanic isolation effectively reduces ground loop interference.
• Low levels of channel cross-talk were attained, crucial for sensitive measurements.

Conclusions:

• The implemented DAQ system provides a robust and high-precision platform for electron EDM measurements.
• The design successfully addresses challenges related to noise and signal integrity in sensitive experiments.
