B_z Probe Analysis in CMFX

The Centrifugal Mirror Fusion Experiment (CMFX) expands on the established concept of the magnetic mirror,

implementing a radial electric field with a central electrode that causes the confined plasma velocity component

to point in the azimuthal direction, thus stabilizing and heating the plasma. Magnetic diagnostics are essential to

understanding the interactions between the plasma and the centrifugal mirror. The design method to construct the

Bz probes consisted of an array of three loops, each with 30 turns and a measured cross-sectional area of 6.5 ×

10^-5 m². The probes are mounted on a window exterior to the vacuum vessel. Each probe was shielded and

connected to a digitizer/oscilloscope for data acquisition. The signals are then filtered, integrated, and detrended

to produce ∆B graphs. FFT and spectral analysis were implemented to identify sources of noise within the ∆B

signals. This builds on our previous results by improving the signal-to-noise ratio using shielding techniques

and by employing Python within Jupyter Lab for data analysis. Preliminary results from the Bz probes suggesting

∆B signals on the order of 10² G at mid-plane will be presented.
