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
- Day 7: Optical Fiber
- Day 8: Electro-Optical Modulator
- Day 9: CCD Camera
As mentioned in the ion pump article, vacuum is very important part of most atomic physics research: have to have a “can” (the vacuum system) where almost everything removed (mostly meaning air, water vapor, other gases), so we can put our physical system there to experiment on. Vacuum pumps do the removal step, and vacuum gauges tell us how much stuff is still in there? Hot filament ionization gauges, or ion gauges for short are such measurement devices to be used for Ultra High Vacuum (UHV).
