Outline For Thesis

Ionization Simulations with GPT Custom Element

Ionization Theory

• Can be pulled from PSTP proceedings and tech notes. Will include:
  • Ionization Cross Section & Production Rate
  • Secondary Electron Differential Cross Section (SEDCS)
  • Ion Energy Distribution (Maxwellian)
  • Momentum/Energy Conservation?

GPT Custom Element Algorithm

• Description of how the custom element works and is used to simulate ionization
• Benchmarking with theory and IBSimu (Can be pulled from future GPT/IBSimu paper)...maybe put in the LIfeSize Runs Section?

Biased Anode To Mitigate Ion Back-Bombardment

• Ion back-bombardment theory & how the biased anode will mitigate it (Can be pulled from PSTP)
• Summer 2019 Biased Anode Experiments
  • Experiments at CEBAF
  • QE Measurements & Charge Lifetime Analysis
  • QE Scan Analysis
  • GPT Simulations (w/custom element)
  • Results/Discussion
• Similar for Winter 2019-2020 Experiments?

Analyzing 2017 LifeSize Runs with GPT/IBSimu

• Description of Experiment
• Analysis of results with GPT custom element
• Comparison & benchmarking with IBSimu

Ion Trapping at the Gun Test Stand (GTS)

• Theory
• Ion Trapping Experiments - Ghost Beam and Steel Shield
• GPT Simulations (w/custom element)
• Results/Discussion
