Abstract: A target substance replenishment device may include a first container containing a solid target substance, a first path through which the solid target substance supplied from the first container passes, a first supply switching device switching between a first state where supply of the solid target substance from the first container to the first path is suppressed and a second state where the supply of the solid target substance from the first container to the first path is allowed, a first valve connected to the first path, a second path which is connected to the first valve and through which the solid target substance having passed through the first valve passes, a first detector outputting a first detection signal indicating that the second path is clogged with the solid target substance, and a processor controlling the first supply switching device to the first state based on the first detection signal.

Abstract: A target supply device may include a tank for storing a target material, a nozzle which is connected to the tank and outputs the target material, and a gas supply section for supplying the tank with gas. The gas supply section may include a booster which is connected to a gas line, boosts the gas supplied from the gas line, and outputs the boosted gas to the tank, a pressure sensor for measuring the pressure inside the tank, and a pressure controller which adjusts the pressure of the gas to be supplied to the tank on the basis of a measurement result from the pressure sensor.
