Nathan Belmore

M.Sc. Researcher

Master’s student in Physics researching at the Max Plank Institue for Plasma Physics in Greifswald, Germany. Studied physics, mathematics, computer science, and machine learning. Previously worked as a software developer (I also set up and maintain this website). Academic research focused on plasma physics and machine learning. 

Academic background

Worked for over 12 years as a programmer and networking engineer. Recently completed degrees in physics and mathematics with an emphasis in data science from U.C. Berkeley and intend to pursue a Masters in physics with topics related to ML at the Max Plank Institue for Plasma Physics in Germany. 

My principal research has been in low energy particle, plasma, and antimatter physics. 

Research objectives

I want to develop new tools for plasma and particle physics using machine learning.

CERN Summer Internship – ALPAH: Antihydrogen Spectroscopy

 

 

Proposed the use of Phase Space Objects as a possible process for mixing antiprotons and positrons to produce antihydrogen. After weeks of preparing the presentation, the idea was approved at the group meeting to be added to the physics agenda. It is still in the physics agenda queue. Several graduate students with ALPHA are looking into using PSE research as their thesis subject when the experiment comes back online. Implemented an automated plasma temperature fitter which would deconvolve the data, apply an iterative fitting process written for CUDA to speed up the calculations, and find the narrow region between the noise and the saturation regime where the data was accurate. Developed a client and server system for the temperature analysis software so the data can be queued up from multiple sources. The software is currently being used by the group.

Production of Coherent Phase Space Excitations – U.C. Berkeley: Physics

 

 

Was the first to notice the effects of the frequency dependence in confined plasma with an RF perturbation, spurring a new research direction. Phase Space Excitations (PSE) are a sub-population of the plasma that is excited by an RF perturbation and separated from the main body of the plasma, similar to autoresonance. Responsible for designing many of the plasma control sequences, circuits, and simulations to examine this phenomenon. Played a major role in the data collection, research direction, and theory development. Presented this research on behalf of our lab at the annual meeting of the APS Division of Plasma Physics (UP12.00041).

Cyclotron-Cavity Mode Resonant Cooling – U.C. Berkeley: Physics

 

 

This research focused on cooling plasmas through cavity mode coupling. Helped develop the plasma control sequences that allowed for a breakthrough in our data collection methods. Also responsible for redeveloping a program designed at CERN called the modes diagnostic, which allowed our group at Berkeley to examine the dipole and quadrupole moments of the plasma. Optimizing the diagnostic software to take data at several times the rate and implemented a better averaging scheme, producing much better signal to noise ratio. Collected a significant portion of the data. The cavity mode resonant cooling research was presented at the APS-DPP and is slated for publication in PRL early next year.

Permanent Electric Dipole of 199Hg – University of Washington: Physics

 

 

This research focused on searching for a permanent electric dipole moment of vaporized mercury in the hopes of finding a source of time reversal symmetry violation. Work was focused on reducing experiential noise by modeling the fields and field noise from the experiment and magnetic shielding. Presented research at UW Undergraduate Research Symposium (2013).

APS Division of Plasma Physics Conference

2015

 

Presented research on the production of coherent phase space excitations in trapped non-neutral plasmas (UP12.00041). Credited on Cyclotron-Cavity Mode Resonant Cooling in Single Component Electron Plasmas (UP12.00040) and Novel Microwave Cavity for Resonant Cooling of a Lepton Plasma (UP12.00043).

 

 

 

U.W. Undergraduate Research Symposium

2013

 

Gave a presentation on the use of finite element analysis to model magnetic flux from magnetic shielding on a low energy particle physics experiment. The symposium is quite large, with almost one thousand presenters.
