Imaging Plasmas with Coded Aperture Methods Instead of Conventional Optics [ PDF ]

Pakorn Wongwaitayakornkul and Paul M. Bellan

Summer Undergraduate Research Fellowships (2012)

I worked on the prototype of coded aperture imaging camera to be used for imaging X-ray coming from magnetic reconnection.

A Tellurium Frequency Reference For Re-pumping During Laser-cooling of Strontium [ PDF ]

Pakorn Wongwaitayakornkul and Thomas Killian

Physics Senior Thesis (2013)

I worked on the development of a new repumping system for laser-cooled strontium atoms using a laser operating at 481 nm. The project includes characterization of the new laser, construction of the temperature control system, and the spectroscopy of the tellurium cell.

A 3D High-Speed Probe for Measuring the Magnetic Components of a Whistler Wave [ PDF ]

Pakorn Wongwaitayakornkul, Xiang Zhai, and Paul M. Bellan

Summer Undergraduate Research Fellowships (2013)

I made a 3D fast (10-30 MHz) magnetic probe for measuring whistler wave from magnetic reconnection

A Non-Invasive Diagnostic Tool for Cardiac Pressure Gradients [ PDF ]

Pakorn Wongwaitayakornkul, Muhammad S. Shamim, Craig Rusin, Elijah Bolin, and Matthias Heinkenschloss

CAAM Senior Project (2014)

We developed a mathematical model to accurately transform echocardiogram data into pressure gradient information accessible to clinicians.

Apex Dips of Experimental Flux Ropes: Helix or Cusp? [ DOI ]

Pakorn Wongwaitayakornkul, Magnus A. Haw, Hui Li, Paul M. Bellan

ApJ, 848, 2 (2017)

We presented a new theory for the presence of apex dips in certain experimental flux ropes.

Reverse Current Model for Coronal Mass Ejection Cavity Formation [ DOI ]

Magnus A. Haw, Pakorn Wongwaitayakornkul, Hui Li, and Paul M. Bellan

ApJL, 862, L15 (2018)

We reported a new model for explaining the three-part structure of coronal mass ejections (CMEs). We proposed that the cavity was formed due to a diamagnetic effect of the plasma in ideal MHD regime. The dynamics of the obeservational, experimental, and simulated flux rope is tested with a simple 1D equation of motion.

Magnetically Induced Current Piston for Generating Extreme-ultraviolet Fronts in the Solar Corona [ DOI ]

Pakorn Wongwaitayakornkul, Magnus A. Haw, Hui Li, Paul M. Bellan

ApJ, 874, 137 (2019)

We proposed a hybrid model where EUV waves are compressional fronts driven by a reverse electric current layer induced by the time-dependent CME core current.

Magnetic Rayleigh-Taylor Instability in an Experiment Simulating a Solar Loop [ DOI ]

Yang Zhang, Pakorn Wongwaitayakornkul, Paul M. Bellan

ApJL, 889, L32 (2020)

We presented an observation of a hoop force driven magnetic rayleigh-Taylor instability in a laboratory experiment simulating a solar coronal loop

Determination of a Macro- to Micro-Scale Progression Leading to a Magnetized Plasma Disruption [ DOI ]

Byonghoon Seo, Pakorn Wongwaitayakornkul, Magnus A. Haw, Ryan S. Marshall, Hui Li, and Paul M. Bellan

PoP, 27, 022109 (2020)

We reported observations and a model of a sausage-to-kink instability sequence that breaks off the plasma and causes a fast magnetic reconnection.

Dynamics of an Arched Magnetically-Twisted Current-Carrying Plasma [ DOI ]

Pakorn Wongwaitayakornkul

PhD dissertation (2020)

Experimental and numerical studies of a dense magnetically-twisted plasma and their applications to solar plasmas are the subject of this dissertation.

3D Numerical Simulation of Kink-Driven Rayleigh–Taylor Instability Leading to Fast Magnetic Reconnection [ DOI ]

Pakorn Wongwaitayakornkul, Hui Li, Paul M. Bellan

ApJL, 895, L7 (2020)

We simulated the kink-driven Rayleigh-Taylor, an MHD instability cascade, using 3D MHD code and compared it with the previous theoretical and experimental results.

Inviscid damping of an elliptical vortex subject to an external strain flow [ DOI ]

Pakorn Wongwaitayakornkul, James R. Danielson, Noah C. Hurst, Daniel H. E. Dubin, and C. M. Surko

PoP, 29, 052107, Cover Article (2022)

We studied the oscillatory motion of a two-dimensional vortex under the presence of an applied strain field. The experiments were performed using columnar electron plasmas in Penning-Malmberg trap. We found that interestingly the damping rate does not change significantly over a wide range of strain rates and we explored other high amplitude perturbation effects.
