Abstract
We present a magnetic cooling chain designed to have a continuous heat sink below 50 mK. It has been focused on providing a cryogen-free and autonomous operation for the users. The challenge is to provide two levels of continuous cooling in order to control the heat balance on the coldest stage. Designed for scientific research and high sensitivity cryogenic detectors applications, the prototype has been validated with a kinetic inductance detectors array. A completely autonomous operation of the cryogenics system from 300 K down to 100 mK has been validated.
