[18p-Z18-19] Effect of time delay in thermocouple circuit on fast heat flux measurement

キーワード:heat flux, thermocouple, Primary delay system

Precious estimation of heat flux is important for material processing or living cells treatment, since it induces target uncontrollable heating and damage. This problem is more serious for fusion divertor plasma heat flux with fast change of ms order. Recently, time delay in the thermocouple circuit was found to put limitation to detect fast heat flux change. A simple mathematical procedure is proposed to model this mechanism and compensate deformed target temperature data.
