Electron Cyclotron Emission (ECE) and Correlation ECE diagnostics on TCV

Electron Cyclotron Emission ( ECE ) and Correlation ECE diagnostic on TCV

The electron cyclotron emission (ECE) and correlation ECE diagnostics in TCV have been upgraded during its 2014 shutdown; this paper will provide a brief overview on their updated architecture and capabilities. The ECE system is equipped with two radiometers, each with 24 channels (750 MHz bandwidth) looking at the plasma both from the low and high field side covering the whole vessel. Of parti...

Oblique and Correlation Ece in Tcv

The Tokamak à Configuration Variable, TCV, is equipped with a moveable ECE receiving antenna, identical to the 6 second harmonic (X2) ECH/ECCD launchers, which can track the plasma at any position within the vacuum vessel in real time. In contrast to this poloidal plane viewing, the receiver can be rotated to obtain an oblique view. In this configuration, measurements of the asymmetry of the el...

Effect of Wall Reflections on Hot Electron Temperature from ECE Diagnostics in LDX

Background The Levitated Dipole Experiment (LDX) at MIT uses a floating donut-shaped supercon-ducting magnet to study the confinement of plasma in a dipole magnetic field. LDX created its first plasma in 2004 and first levitated its su-perconducting magnet in 2007. Compared to the more popular tokamak, first used to create plasma in the 1960s, LDX is a relatively new device. Despite this, there...

Ece 120

This set of notes explains the process that Prof. Jones used to develop the FSM for the lab. The lab simulates a vending machine mechanism for automatically identifying coins (dimes and quarters only), tracking the amount of money entered by the user, accepting or rejecting coins, and emitting a signal when a total of 35 cents has been accepted. In the lab, we will only drive a light with the “...
