David K. Shin Bryce M. Henson, Kieran F. Thomas
Magnetostatic field calculator for trapping neutral atoms Status: This Code is ready to be used by experts, it is still in DEV. Comparative Unit Testing is implemented for most functions. Integration/system testing against analytical trap calculations is not implemented.

• Multiple magnetic feild sources

  • arbitrary path numeric solver
  • loop (analytic)
  • line (analytic)
  • helix (numeric)

• Trap Charaterization

  • gradient decent to find the trap center.
  • finds trap frequency
  • Finds the trap depth via jacobian magnitude decent to find the critial points of the poential.

• Plots

  • 2d slice
  • 3d potential

• Traps implmeneted

  • Biquic https://doi.org/10.1016/j.optcom.2006.09.031

  

  

Install

then to update

git submodule update --remote --merge

To Do

contributors welcome! Drop me an email .

• Documentation
• fix trap depth caluclation to work in 3d
• implement flat spiral current source
• find the principle axes of the trap (dont just assume cartesian)
• implement other trap geometeries
• coherent output struct
• add in multiple potential sources
  • gravity
  • optical
• implement current helix
• build comparative test of sources
