I now have the drawings of my two fridges, designed by Arlette at Leiden Cryogenics. One fridge will have a solenoid magnet, and the other – a 2-axis vector magnet. One challenge was to keep the field centers (where magnetic field is maximum) in both fridges the same distance from the top. This is needed to be able to load samples into either of the fridges using the same probe, while the fridges are cold. After some negotiations with magnet manufacturers we worked it out!
Each machine will have two ports for loading samples, so two experiments can be performed in each fridge at the same time! Leiden promise to begin assembling the first fridge in July. Today is July 1st, so lets put some pressure on them using the power of blogging.
