This Advent during the 24 days leading up to Christmas I thought it would be fun to have a quick introduction of scientific apparatus, in particular tools used in atomic physics research. This is a way to say thanks to their hard work for our research, and a look at how many things are really needed to make a laboratory work!
- Day 1: Acousto-Optic Modulator
- Day 2: Ion Pump
- Day 3: Photomultiplier Tube

Magnetic Field Coils
The physics of atoms is in general very sensitive to magnetic fields, so there’s two big area where a lot of work has been done: on one hand – how to control magnetic fields well so that we can make the atoms do what we want them to do (by changing the atoms’ energy levels and thus their interactions), and on the other – how to find atomic systems that they are not sensitive to magnetic fields, which does get rid of issues. There’s a lot more of the first case, and usually magnetic field coils are used in the lab to create the “right kinds” of fields for the specific experiments.
