The present nuclear physics program at the National Superconducting Cyclotron Laboratory (NSCL) is based on an ECR-ion-source injected K1200 superconducting cyclotron. An upgrade project is now underway to significantly increase the facility’s output intensity for light ions and energy for heavy ions by coupling the existing superconducting K500 cyclotron to the K1200. The improved acceleration...

We describe the development of a Cyclotron Mass Spectrometer (CMS) for the detection of trace amounts of rare isotopes. A compact low energy cyclotron optimized for high mass resolution has been designed and fabricated. The CMS has high sensitivity and is designed to measure 14C at abundances of 10-12. A novel feature of the CMS is the use of permanent magnets to energize the 30 cm diameter iro...

An electron cyclotron emission (ECE) receiver inside the electron cyclotron resonance heating (ECRH) transmission line has been brought into operation. The ECE is extracted by placing a quartz plate acting as a Fabry-Perot interferometer under an angle inside the electron cyclotron wave (ECW) beam. ECE measurements are obtained during high power ECRH operation. This demonstrates the successful ...

The study of the relativistic dynamics of charged particles moving in electric and magnetic fields is of prime importance in accelerator and plasma physics, where such devices as the cyclotron, tokamak, and free-electron laser are frequently encountered [1,2]. The recent surge of interest in this study stems partly from theoretical and experimental findings that such particles are capable of ex...

[1] Ion cyclotron motion can play a role in shaping magnetospheres and governing magnetospheric dynamics, particularly in weakly magnetized systems such as the moons of outer planets. However, MHD explicitly neglects such effects. We demonstrate the importance of ion cyclotron motion in the near space environment of Ganymede using 3-dimensional multi-fluid simulations to account for Galileo mag...

We have investigated the role of the cyclotron emission associated to cosmic magnetic fields on the evolution of CMB spectral distortions by considering the contributions by spontaneous and stimulated emission and by absorption in the computation of the photon and energy injection rates. These cyclotron emission rates have been numerically compared with those of the relevant radiative processes...

The spectrum of cyclotron radiation produced by electrons with a strongly anisotropic velocity distribution is calculated taking into account higher harmonics. The motion of the electrons is assumed to be ultrarelativistic along the magnetic field and nonrelativistic across the field. One characteristic feature of the resulting spectrum is that harmonics of various orders are not equally spaced...

In the reversed field pinch ions are heated anomalously relative to collisional energy exchange with Ohmically heated electrons. The process channels electron energy to ions in a way that is still not understood. Recent observations suggest that impurities are preferentially heated. A theory for ion heating via impurity ioncyclotron-resonant damping of the turbulent energy cascaded from unstabl...
