  15. Parameters Set in Piece Windows • Units choices for each parameter - standard units (i.e. eV, keV, MeV, …) - “smart units” (i.e. b, g, p0, …) • “Green Dots” provide feedback - Indicate parameters that will be used for calculation with the optics code displayed in “Context Switch” • Several “Feedback Only” parameters G.

  28. Optics Codes: How PBO Lab Works • Optics code executions run from GUI -applied to Model Space object model • Object model also contains optics code specific instructions • PBO Lab writes input files, calls optics code to execute instructions, then displays requested outputs G.

  33. Example of Use (LLUMC) • Determination of beam parameters at the exit of the Loma Linda University Medical Center (LLUMC) proton therapy synchrotron Utilized 2 Modules (+ Basic) TRANSPORT Module Optimization Module G. H. Gillespie Associates, Inc.

  34. Example of Use (LLUMC) • Designing an advanced scanning capability for proton treatment requires detailed knowledge of extracted beam • More details of beam extracted from synchrotron needed, but no room in beamline for new diagnostics • Can the existing beam size monitors be used to determine the beam? G. H. Gillespie Associates, Inc.

  35. Example of Use (LLUMC) • TRANSPORT to compute beam size • Select beam x, x’, y, y’, r12, r34 as Optimization Variables • Add Optimization Constraints on: emittances, momentum spread, … • Optimization Module fits TRANSPORT beam sizes to measured sizes (s) G. H. Gillespie Associates, Inc.

  36. Example of Use (LLUMC) • All initial conditions converged to the same solution • Sensitivity studies easy to perform G. H. Gillespie Associates, Inc.

Gillespie Associates, Inc.

  38. Why this Example (LLUMC)? From page 703 of reference 3 (preceding slide): “In a previous publication, we adjusted the emittance parameters by “trial and error” using TRANSPORT until a good visual agreement with measured beam sizes was obtained. This was quite laborious and not as precise as the use of an objective function to minimize the difference between measured beam sizes and TRANSPORT calculations. The PBO Lab implementation of the NPSOL and MINOS optimizers can rapidly change the initial beam properties, and recalculate the beam size at selected points and then compare them to the measured values.” From an earlier presentation of results at a PTCOG meeting: “The beam transport optimizer from AccelSoft has shown great value in saving many days and even months in finding the best emittances for beam studies at the LLUMC proton accelerator facility.” G. H. Gillespie Associates, Inc.

  39. Plans for Future Enhancements • More Modules Built with OASIS • ATMG – “Quick and Easy” Transfer Maps – From Computed Field Data – From Measured Field Data • Open to Suggestions! G. H. Gillespie Associates, Inc.
