Keywords:GAMMA 10/PDX, thermocouple signal noise, heat flux estimation

There is often electromagnetic noise in thermocouple temperature signal, which is used in time dependent heat flux measurement. In this work, reference channel which does not receive plasma heat flux is prepared and subtract only this noise from plasma irradiated target temperature signal.
