摘要： A thermal management system comprising: a thermal source of low to cryogenic temperature; a heating element for heating the source; a shield adapted to exchange heat by conduction to/from a sample and to/from the source; a controller calibrated for maintaining a gradient of temperature along the shield within a pre-determined range; a vacuum sealing feedthrough comprising a thermal insulator element, the vacuum sealing feedthrough delimiting around the first interface a vacuum sealed volume so that the shield exchanges heat with the thermal source exclusively by conduction and exclusively at a first interface. An exemplary purpose for this thermal management system is the sublimation of water ice and/or water ice trapped in a regolith, and positioned in a vacuum chamber. The heat insulator element is configured to separate physically the thermal source from a vacuum chamber into which the shield can protrude, so that sublimated compounds from the sample do not encounter colder point which would cause their deposition on the shield or on the walls of the chamber.

摘要： A system and method for sublimation of water ice and/or water ice from a regolith. The system comprises a sublimation chamber under high to ultra-high vacuum into which protrudes a shield of a thermal management system. Sublimated water is collected to be further analysed or analysed in-line. For instance, cold traps can be used to trap water and transfer it to sample tube for analysis.
