Biography

Alex Creely is a PhD student in the Department of Nuclear Science and Engineering working at the Plasma Science and Fusion Center.  He is interested in various aspects of magnetically confined fusion energy. Alex's thesis work focuses on detailed measurements of plasma turbulence and comparison to turbulent transport simulations, with the dual goals of better understanding turbulence and using these codes to predict the performance of future experiments. This research has taken him to various fusion experiments around the world, most recently to Munich, Germany and Nagoya, Japan.  Before coming to MIT, Alex completed his Batchelor of Science and Engineering in Mechanical Engineering at Princeton University.

Research

MIT Plasma Science and Fusion Center, 2014 – Present 
Alcator C-Mod Core Transport Research GroupInvestigated perturbative thermal transport on the Alcator C-Mod and ASDEX Upgrade tokamaks via heat pulses generated by the partial sawteeth.  Constructed Correlation Electron Cyclotron Emission (CECE) diagnostics for C-Mod and ASDEX Upgrade.  Validated gyrokinetic and gyrofluid simulations with GYRO, GENE, and TGLF.

National Institute for Fusion Science, Toki, Gifu Prefecture, Japan, Summer 2016
MIT International Science and Technology Internship (MISTI) Intern
Investigated differences in turbulent density fluctuations measured on the reflectometer, phase contrast imaging (PCI), and charge exchange spectroscopy (CXS) on the Large Helical Device (LHD) stellarator.

Princeton University Senior Thesis, 2013 – 2014
Thermal Desorption from Hydrogen-Carbon Co-Deposition Layers for Fusion Applications
Investigated the prospect of removing hydrogen isotopes from co-deposition layers of carbon via thermal desorption. Utilized a modified quartz crystal microbalance (QCM) setup with GaPO4 crystals.  Confirmed qualitatively that such desorption is possible and merits further research.

General Atomics DIII-D, San Diego, CaliforniaSummer 2013
National Undergraduate Fellowship Intern                        
Analyzed data collected from the Beam Emission Spectroscopy diagnostic on the DIII-D magnetically confined fusion Tokamak.  Used IDL code to study the evolution of turbulence and its effect on plasma containment near the edges of the containment field.

Princeton Plasma Physics Laboratory, Summer 2012
Science Undergraduate Laboratory Internship (SULI) Summer Intern
Conducted simulations to investigate the slowing of energetic particles in background plasma with different magnetic fields using the Large Scale Plasma (LSP) Particle in Cell (PIC) code.  Utilized results to determine the differences in plasma heating in Tokamaks and in Field Reverse Configurations.
