Fridge update

Meanwhile in Leiden they have installed the pulse tube on our first fridge. This is a major component that allows the fridge to operate without consuming liquid helium, in the dry mode. The pulse tube cools the system down to a few Kelvin by running helium in a closed loop. This makes a dilution fridge more like a fridge in your kitchen, a plug-in electrical appliance.
