Measured sub-millimeter synchrotron background in Alcator A – implications for D2O laser Thomson scattering

P. Woskoboinikow, H.C. Praddaude, I.S. Falconer, W.J. Mulligan1981年被引用 1Nuclear FusionIF 3出版社

A sub-miliimeter-wave heterodyne receiver designed for a D2O laser Thomson scattering ion temperature diagnostic has been used to measure the synchrotron emission from the Alcator A tokamak at 762 ± 11 GHz down to levels of 10−20 W·Hz−1. A comparison with predicted Thomson-scattered signal levels indicates that the measured background will be much lower except near the third electron cyclotron harmonic for fields near 9 T.

D2Oレーザートムソン散乱イオン温度診断用に設計されたサブミリ波ヘテロダイン受信機を用いて、アルカトールAトカマクからのシンクロトロン放射を762±11GHzで10⁻²⁰W・Hz⁻¹のレベルまで測定した。予測されたトムソン散乱信号レベルとの比較により、9T付近の磁場における第3電子サイクロトロン高調波付近を除いて、測定されたバックグラウンドははるかに低いことが示される。
