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
In atomic physics experiments the sequence is usually preparing the physical system in a particular way, then doing something with it, finally measuring somehow what is the outcome of our manipulation. This last step is quite often done by “taking a look”, literally, recording some kind light signal of the system. If we are only interested in the amount of light, then might just use a photomultiplier tube. On the other hand, if we also want to know how things are laid out in space, then we need a camera, and to get handy electric signal as the image, it can be a charge-coupled device (CCD) camera.
