The logbook

One short entry per spaced session — not a report, a thinking trace. The tutorial is built around these, so write them as you go, not the night before.

Five fields, ninety seconds

Each interactive ends by asking for one logbook entry. They all use the same five prompts. The one that matters most is the fourth — it is where the critical thinking shows.

Tried what you actually did — which interactive, which setting, which exercise.
Stuck where you got stuck, and roughly how long before it moved (or didn't).
Hub resource used which anchor, reference card, or “go broader” source you reached for.
Changed my mind because… the one belief this session overturned. If nothing changed, say why you started right.
Still unclear the question you are carrying into the tutorial.

What a good entry looks like

A strong entry names a specific wrong turn and the evidence that corrected it — not “I learned about magnetometers.” Example, from Anchor 1 (the trade-off triangle):

Session 1 · Anchor 1 — choose a magnetometer for 10 nT @ 1 kHz

Tried

Dragged P into the 1 kHz target zone; read the four magnetometer rows against it.

Stuck

~10 min — I assumed I needed the most sensitive sensor (SQUID), but the target-zone readout kept insisting sensitivity wasn't the binding constraint.

Hub resource used

Anchor 1 reference card — the boundary line “more sensitivity is not strictly better” — and the magnetometer table.

Changed my mind because…

10 nT is a large field; every row resolves it, so bandwidth, not sensitivity, decides. I'd been optimising the wrong corner.

Still unclear

Whether NV-diamond's room-T, µm-scale advantage outweighs its modest sensitivity for a real 1 kHz job, or whether SERF-OPM's fading bandwidth rules it out first.

The rhythm — three sittings, not one

Spread the three entries across the week (the workshop tracks your ticks). Each 30-min session is ~2 anchors and one entry; the tutorial discusses all three.

Session	Anchors	One entry about…
1 · early week	1 triangle · 2 noise/Allan	the design task + the noise-trace task
2 · mid week	3 SQL · 4 ladder	coin-flip / photon-counting + pick-the-rung
3 · late week	5 back-action · 6 transduction	squeezing-band task + a broken transduction chain
