In our experiment we have a 1 W closed-cycle, low-vibration 4 K cryostat which  refrigerates the Paul trap of the highly charged ion (HCI) experiment.  An extreme high vacuum is achieved providing long HCI storage times on  the order of 45 min. A vibration suppression system ensures a  mechanically...
