The electron cyclotron (EC) system of ITER for the initial configuration is designed to provide 20MW of RF power into the plasma during 3600s and a duty cycle of up to 25% for heating and (co and counter) non-inductive current drive, also used to con

Feedback-free optical cavity with self-resonating mechanism

Autor: Uesugi, Y., Hosaka, Y., Honda, Y., Kosuge, A., Sakaue, K., Omori, T., Takahashi, T., Urakawa, J., Washio, M.

We demonstrated the operation of a high finesse optical cavity without utilizing an active feedback system to stabilize the resonance. The effective finesse, which is a finesse including the overall system performance, of the cavity was measured to b

In a conventional positron source driven by a few GeV electron beam, a high amount of heat is loaded into a positron converter target to generate intense positrons required by linear colliders, and which would eventually damage the converter target.
