Equipment issues. Matching Networks (MN).

Pulsed power may disrupt automatic MNs.
- Tuning can become very poor. (MN “confused” by time dependent power.)
- The best match point is often NOT the same as that in the steady state regime or for a continuous plasma.
MN settings determine the plasma stability.
- “Tune” for earliest plasma ignition (during each pulse period)?
- “Tune” for highest net power transfer? (Lowest reflected power and largest steady state regime electron density.)
- Hold “tune” point constant over the processing time (or let the MN vary on the seconds time scale)?
MNs can deposit (stored) power during the turn-off regime.
