The spectral characteristics of fluctuation induced particle transport in the scrape-off layer region (SOL) of the ADITYA tokamak are measured. The transport is found to be inward at frequencies lower than 20 kHz and outward at higher frequencies. The sense of the observed inward particle transport is in agreement with that predicted by ionization driven drift wave turbulence theory. This observation suggests a very interesting method of controlling the particle confinement time by partial control of the long wavelength ionization instability

ADITYAトカマクのスクレイプオフ層領域(SOL)における揺動誘起粒子輸送のスペクトル特性を測定した。輸送は20 kHz未満の周波数では内向きであり、より高い周波数では外向きであることが見出された。観測された内向き粒子輸送の方向は、電離駆動ドリフト波乱流理論によって予測されるものと一致している。この観測は、長波長電離不安定性の部分的な制御による粒子閉じ込め時間の制御という非常に興味深い方法を示唆している。
