Ion cyclotron resonance heating system in the RT-1 magnetospheric plasma

Abstract: We have developed an ion cyclotron resonance of frequencies (ICRF) heating system for the Ring Trap 1 magnetospheric device. We excite slow waves from the polar region of the dipole magnetic field. The target helium plasma is produced by electron cyclotron heating. The electrons comprise high-temperature (>10 keV) and low-temperature (<100 eV) components with both typically exhibiting the densities of same order of magnitude. The ICRF heating causes an increase in the ion temperatures and toroidal flow velocit… Show more

“…Такие ловушки называют также «Галатеями» в соответствии с работами [1][2][3]. К данному типу установок относятся ловушка «Диполь» с одним левитирующим проводником (см., например, [4][5][6][7][8][9][10][11][12]), токамакообразные «Левитроны» и «Сфератор» [13][14][15], мультипольные «Галатеи» с несколькими левитирующими кольцевыми проводниками [16][17][18], «Торнадо» [19][20][21], левитирующий октуполь [22], а также мультипольные ловушки «Тримикс» и «Тримикс-3М» с различным числом левитирующих проводников с током [1-3, [23][24][25][26][27][28][29][30][31][32].…”

“…For helium plasmas, the CIS measured the spectral intensity, ion temperature, and flow velocity of He + . We successfully demonstrated ion-cyclotron-resonance-frequency (ICRF) heating of magnetospheric plasmas [12]. The 10 kW input power of electron-cyclotron heating (ECH) sustained the target plasma.…”

“…While linear traps can contain positrons and electrons simultaneously [10,11], this has not yet been demonstrated with both species achieving plasma densities in the same volume. Toroidal traps with closed magnetic field lines, such as the stellarator [12,13] and the levitated dipole [14][15][16], more readily confine positive and negative charges simultaneously, but injection from outside these devices is inhibited by the same physics that traps particles inside; electron-ion plasmas are typically ionized within the confinement region. Inward transport into a dipole due to turbulent interactions at high particle densities has been demonstrated for an electron beam [17]; however, typical particle densities of positron beams are well below the threshold for such collective interactions [18].…”
