New paper published on analyzing and mitigating pulse-pile-up artifacts in PFRC-2 plasma x-ray spectra
A new paper, “Analysis and Mitigation of Pulse-Pile-Up Artifacts in Plasma Pulse-Height X-ray Spectra” by Taosif Ahsan and our team has been published open-access in MDPI Plasma. It describes the implementation of an algorithm, the two-photon trapezoidal uncorrelated-pulse model, to improve analysis of x-ray spectra emitted from PFRC-2 plasma. This model was developed to reduce…

Plasma oscillations seen in seed and RMF plasma using Phantom Camera
The plasma rotation of the PFRC is being analyzed by the Phantom Camera in the Princeton Plasma Physics laboratory. The above media was taken when we were running with the Rotating Magnetic Field (RMF) Heating System. The video from 10 to 23 seconds shows the plasma rotations are more pronounced and then stabilized later on.…

Upgrade underway of Princeton Field Reversed Configuration-2
The Princeton Field Reversed Configuration-2 (PFRC-2) upgrade in field and frequency is underway. We are currently installing new coils around the experiment to increase the magnetic fields and new capacitors to help lower the RF operating frequency – all to reach our target milestones of measuring ion heating! This is an essential next step in…
