Abstract
The ion cyclotron resonance frequency (ICRF) heating system on JET is currently being upgraded to validate new matching concepts in view of coupling ICRF power to ITER-like plasmas and to further increase the total additional heating power on JET. The present paper reports on first testbed results from the new JET ITER-like antenna as well as on the first use of the newly installed hybrid couplers between two of the existing A2 antennas. Several other on-going improvements, such as improved trip management system, external conjugate-T matching circuit and arc detection systems are also discussed.
