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
- Day 4: Vapor Cell
- Day 5: Analog-Digital Converter
- Day 6: Magnetic Field Coils
A lot of work in atomic physics is done with laser light, and the problem there is how to get the light from where it is to where it is, to where it needs to be. Sometimes that can be done just in the air (or “free space”) pointing the light onto the target. But sometimes it is not possible. It might be because of safety, maybe because of issues with stability how well we can point things, or even just as simplicity to decouple the “where is it coming” and “where does it go” parts from each other. In this latter case usually an optical fiber is used.
