Proposal Title: Creating Space Plasma from the Ground
ABSTRACT:
It was predicted (Carlson, 1993) that once high power HF transmitters achieved the Giga­Watt ERP level, they
would from the ground produce plasma densities competitive with that produced by the sun, thereby breaking
through a new threshold of progress for space science research. Only now has technology allowed testing that
prediction, with two publications confirming it (Blagoveshchenskaya et al, 2009; Pedersen et al, 2009). The initial
prediction was based on Arecibo HF heating experiment data (Carlson et al, 1982). The confirmations however
involve processes expected to be important only at high latitudes (Gurevich, Carlson and Zybin, 2001). The
purpose of this proposal is to learn how well the initial prediction scales to higher power densities, plus in light of
current theory, test important dependencies on further geophysical processes now anticipated to be important. We
know some ionization must be produced, we don' t know what processes determine significant production.
