The field of cryogenics has developed hugely in the last century and now requires knowledge of a wide variety of scientific disciplines from low-noise electronics through to high vacuum technology, in addition to the basics of handling liquified gases and dealing with materials whose properties can be radically different from those at room temperature.
Before the invention of the internet and other collaborative tools it could take many years of practical design exposure to acquire the knowledge to be able to develop or use cryogenic equipment with confidence.
Here we hope to make that journey quicker and slightly more enjoyable - so sit back, grab a coffee and let's begin ...
