Cyclotron resonance in cadmium telluride
"Cyclotron resonance experiments have been performed on single crystals of high purity, n-type CdTe at 4.2°K. A reflection type microwave spectrometer was employed, operating at a frequency of 70 Gc. The mass and the mobility of the carriers, as determined from the resonance spectra, identify the …

Pulsed mm-Wave electron cyclotron maser experiments
A pulsed Electron Cyclotron Maser (E. C. M.) was developed and used to generate high power mm-waves in the W-band (75-110GHz) and the G-band (150-220GHz) frequency ranges. The relativistic electron beam (R. E. B.) was produced from a field-immersed, field-emission, cold cathode. A shaped anode …

Numerical modeling of electron cyclotron resonance plasma
… semiconductor industry is introducing electron cyclotron resonance (ECR) plasma reactors as reliable wafer etching tools. This industry requires radially uniform etching rate and radially uniform etching anisotropy. The etching rate and etching anisotropy depend on the ECR plasma properties.

Copper metallization with an electron cyclotron resonance
An "electron cyclotron resonance" plasma source, used for physical vapor deposition of copper into sub-micron features, was studied to determine whether parameters, such as gas atom density, electron density and temperature, surface bias, and copper ionization fraction at the deposition surface, …

Control and characterization of a cyclotron proton beam
The cyclotron proton beam accelerator at the University of Missouri Research Reactor (MURR) is used for positron emission tomography (PET) applications. Pharmaceutical radioisotopes are produced and delivered to local hospitals for cancer diagnosis and nuclear imaging. The proton beam's energy is …

Charged particle beam transport for a cyclotron facility
… refer specifically to beamlines to or from a cyclotron, while others may be used in beamlines from any accelerator. In the former category, we develop a method for determining the eigen-ellipsoid in all six dimensions of phase space, when the beam under consideration is to be (a) extracted …

Multiple frequency electron cyclotron heating for the Levitated Dipole Experiment
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 …

Bayesian analysis of electron cyclotron emission measurements at Wendelstein 7-X
Electron cyclotron emission spectroscopy (ECE) is a standard diagnostic technique on the optimized stellarator Wendelstein 7-X (W7-X) that can record data with a high resolution in time. The spatial assignment via the blackbody emission of a plasma layer depends on the optical depth and thus plasma …

Low temperature epitaxial silicon growth using electron cyclotron resonance plasma deposition
… wafers are not used. We have used electron cyclotron resonance (ECR) plasma deposition to grow high quality epitaxial silicon films on silicon wafers. This growth technique relies on the deposition of silicon from a highly energetic hydrogen and silane plasma. The presence of the hydrogen in …
