2026-Sep-01 20:18:55 Here's the calculation for the #RF field model derived from behaviour near the axis. The RF multipole case got quite complicated, maybe there's a simpler way but I wanted to see if this method, which I'd used for magnetostatics (magnet field models), could be generalised.

2026-Sep-01 16:06:08 The electric (blue) and magnetic (orange) fields in an analytic model of an #RF dipole deflector. I wanted a series solution that I could use in particle tracking calculations, taking a function f(z) that's the intensity of the field on-axis and then working out the rest using Maxwell's equations and the desired frequency and symmetry. It took a while to derive and debug but it does appear to satisfy Maxwell's time-dependent equations now! #physics #accelerators |

2026-Aug-30 18:35:42 Did a lazy mow of the lawn. Some bits are growing faster than others, so I just mowed what seemed long. 🌱 |
