Abstract
An X-ray detector used in an energy-dispersive X-ray spectrometer The detector comprises a cooling vessel containing liquid nitrogen and a protective container enclosing the cooling vessel. The space between the cooling vessel and the protective container is hermetically partitioned into a dewar tank portion and a nose portion by a partition wall. An X-ray detector device is accommodated in the nose portion. If the liquid nitrogen inside the cooling vessel evaporates, the produced gas stays only inside the dewar tank portion and does not enter the nose portion.
