A Pockels cell enabled heterodyne Phase Contrast Imaging diagnostic for detection of Ion Cyclotron Emission
<|begin_of_text|><|start_header_id|>system<|end_header_id|> You are a research archivist expert in dataset metadata. Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'This  work  describes  a  novel  optical  heterodyne  detection  scheme  that  significantly  extends  the  frequency response of the Phase Contrast Imaging (PCI) method to detect electron density fluctuations in tens of mega-hertz frequency range.  The system employs a variable frequency electro-optic modulator to allow operation at any frequency in the range 10–40 MHz without the need to re-align the system.  The frequency coverage of  the  system  makes  it  suitable  to  measure  the  radial  structure  of  the  electron  density  component  of  Ion Cyclotron  Emission  on  devices  having  confining  magnetic  field  of  a  few  Tesla,  thus  extending  the  purely temporal measurements provided so far by magnetic probes' .
