This contribution addresses the electromagnetic feasibility of a wireless temperature monitoring inside a portion of a high-power high-frequency Cyclotron Auto-Resonance Maser (CARM) for plasma heating in the new generation of DEMO TOKAMAK machines. The scenario is investigated as potential communication channel for a UHF RFID sensor network where a cavity probe is used to both excite the coaxial cavity and to collect the temperature data scattered back by sensor antennas. Some preliminary designs and prototypes of a simplified model of the cavity and of the reader/sensor devices permit to quantify the feasibility of the architecture and to evaluate the power bounds for stable communication and sensing. © 2017 Euraap.

Abstract

This contribution addresses the electromagnetic feasibility of a wireless temperature monitoring inside a portion of a high-power high-frequency Cyclotron Auto-Resonance Maser (CARM) for plasma heating in the new generation of DEMO TOKAMAK machines. The scenario is investigated as potential communication channel for a UHF RFID sensor network where a cavity probe is used to both excite the coaxial cavity and to collect the temperature data scattered back by sensor antennas. Some preliminary designs and prototypes of a simplified model of the cavity and of the reader/sensor devices permit to quantify the feasibility of the architecture and to evaluate the power bounds for stable communication and sensing. © 2017 Euraap.
