Abstract
A temperature difference calculation unit determines a temperature difference between a temperature measured by a first temperature measurement mechanism and a temperature measured by a second temperature measurement mechanism. The first temperature measurement mechanism is disposed on an outer wall surface of an inner container at a position corresponding to an element-arrangement-side space in the inner container. The second temperature measurement mechanism is disposed on an outer peripheral surface of a heater. The heater is disposed outside an outer container that accommodates the inner container and positioned on a wall surface of the outer container.
