御装置。[Scope of Claim for Utility Model Registration] An economizer installed in the middle of the outlet piping of the cold trap and configured to use the sodium in the outlet piping as a cooling source, and an economizer installed to pass through the economizer and cooled by the economizer. a detector that detects the lowest temperature of the sodium in the cold trap; a function generator that generates a target value of the cold trap inlet temperature based on the temperature signal from the plaking meter; a circuit that takes an inlet temperature deviation from a cold trap inlet temperature target value; a generator that sets a target value of the cold trap minimum temperature; a circuit that takes the minimum temperature deviation between the minimum temperature target value and the minimum temperature; and an inlet temperature. Calculate deviation and minimum temperature deviation. a proportional-integral-differential calculator; a controller that controls the 117 rotation speed of the cooling device or the damper opening degree based on the calculation result; and a cold trap minimum temperature target value and a minimum temperature are compared, and the minimum temperature is determined to be the minimum temperature target value. 1. A cold trap control device comprising: a circuit capable of switching the temperature deviation of the input of the proportional-integral-derivative calculator from the inlet temperature deviation to the minimum temperature deviation when the temperature deviation approaches the temperature deviation value.
