2026-Oct-31 18:46:01 I was thinking about how to best order items in a to-do list when I realised this is a classic problem of one list with multiple orderings: you can order it by date task added, date task completed, percentage completed, task size and maybe others. |

2026-Oct-12 19:57:49 Connected the 397nm #laser to the wavemeter for the first time and got my first (open loop) frequency stability measurements. Doesn't look bad, the drift is slow so that noise might be reduced with more averaging. The linewidth for Ca+ ion Doppler cooling is 23MHz so it's in the right order of magnitude already. Ignore the five stacked attenuators. #physics #accelerators

2026-Oct-09 23:14:27 I got about 20mW coupled from both lasers, including the 397nm one whose fibre core is only 2.4 microns wide. By hand, using Allen keys. Only to discover the wave-meter I use has a 0.5mW input power maximum. |
2026-Oct-08 20:35:52 Coupling power from this 866nm #laser into a single-mode fibre took some aligning, but I got 1/3 of it in: 23mW of about 70mW total. It helped when I installed the lenses and fibres for the correct wavelength range (it also helped when I hadn't bolted the coupler to the wrong set of holes and lost most of the beam). #physics

2026-Oct-02 19:35:41 Turns out my pixel shader can be extended to simulating something more like a real accelerator cell with nonlinearities. This the dynamic aperture of a FODO cell with a sextupole defect in the F magnet, while I change the F magnet strength. Top left is real space XY, then X'Y', bottom left is XX' phase space, bottom right is YY'.
You can click and drag to change the F and D magnet strengths yourself at https://shadertoy.com/view/fXG3Wh (may require a strong graphics card) #physics #accelerators #nonlineardynamics |
