Thesis (S.M. and S.B.)--Massachusetts Institute of Technology, Dept. of Nuclear Engineering, 2005. / Includes bibliographical references (p. 75-76). / The use of multiple frequencies of electron cyclotron resonance heating (ECRH) in the Levitated Dipole Experiment (LDX) is an important tool that will tailor the plasma profiles. Initial LDX plasmas have been created using 2.45 GHz and 6.4 GHz, both at up to 3 kW. The construction and calibration of the ECRH system will be discussed and initial experimental results will be presented. The effects of different combinations of pulse lengths and powers will be examined in terms of the plasma diamagnetism. Different density profiles will be used to calculate the locations of the resonances and cutoffs. Locations where the plasma absorbs the microwave power will be simulated through computer codes. Equilibrium output of the program DIPOLEQ combined with MATLAB calculations using the Appleton-Hartree dispersion relation provide qualitative representations of where the power is absorbed in typical LDX plasmas. / by Scott B.
