Notes
In the over-dense ionosphere: To determine the energy spectrum of HF pump- induced accelerated electrons resulting from various plasma resonances. In the under-dense ionosphere: To determine whether purely collisional heating of a plasma can produce artificial optical emissions. For both the above cases, we will measure the neutral temperature increase resulting of ionospheric modification for the first time, along with the ion and electron temperatures. For an overdense ionosphere, the Heater will operate in a standard cycle of 2-min on, 2-min off in O-mode. The beam pointing will alternate between field-aligned and vertical. For an underdense ionosphere, the Heater will operate in a standard cycle of 2-min on, 2-min off with beam pointing field-aligned. The polarisation will alternate between O-mode and X- mode. The UHF monostatic radar will track the Heater beam using a standard radar code, e.g. beata. Moon-free, cloud-free sky and geomagnetically quiet conditions are required. Cancellations are anticipated.
