Analysis and mitigation of pulse-pile-up tail artifacts in warm-plasma pulse-height X-ray spectra
Taosif Ahsan, Charles Swanson, Christopher Galea +4
Pulse pile-up in pulse-height energy analyzers increases when the incident rate of pulses increases relative to the inverse of the dead time per pulse of the detection system. Chan…
The effect of rigid electron rotation on the Grad-Shafranov equilibria of a class of FRC devices
C. P. S. Swanson, S. A. Cohen
Rigid electron rotation of a fully penetrated Rotamak-FRC produces a pressure flux function that is more peaked than the Solov'ev flux function. This paper explores the implication…
Spontaneous multi-keV electron generation from Fermi acceleration and magnetic moment non-adiabaticity
C. Swanson, S. A. Cohen
X-ray emission shows the existence of multi-keV electrons in low-temperature, low-power, capacitively-coupled RF-heated magnetic-mirror plasmas that also contain a warm (300 eV) mi…
Using Poisson-regularized inversion of Bremsstrahlung emission to extract full EEDFs from x-ray pulse-height detector data
C. Swanson, P. Jandovitz, S. A. Cohen
We measured Electron Energy Distribution Functions (EEDFs) from below 200 eV to over 8 keV and spanning five orders-of-magnitude in intensity, produced in a low-power, RF-heated, t…
