Magnetic Injection Coils

WP 11083

Cabling for the Magnetic Injection Coils complete. Locations for each coil listed below:

  1. Corner Station - Vertex
  2. Corner Station - SQZ Bay
  3. Corner Station - CER
  4. EX - VEA
  5. EX - Electronics Bay
  6. EY - VEA
  7. EY - Electronics Bay

The injection signals are run from a PEM AI chassis to an audio amplifier. Amplifier is powered on/off by a Pulizzi (switchable AC power port). Currently the Corner Station Vertex and EX VEA units are not connected to a Pulizzi. Both amplifiers were left powered on with drive signal set to 0V. Pulizzi units should not be disconnected as we plan to run injections on Tuesday mornings. Pictures attached of two installations.
