Energy per reaction is the energy released in each fusion reaction; This equation is typically averaged over a population of ions which has a normal distribution. The result is the amount of energy being created by the plasma at any instant in time. Lawson then estimated [5] the radiation losses using the following equation:
A fusion energy gain factor, usually expressed with the symbol Q, is the ratio of fusion power produced in a nuclear fusion reactor to the power required to maintain the plasma in steady state. The condition of Q = 1, when the power being released by the fusion reactions is equal to the required heating power, is referred to as breakeven , or ...
This corresponds to a total scientific energy gain of 0.7 and a capsule energy gain of 6. [14] While the experiment fell short of ignition as defined by the National Academy of Sciences – a total energy gain greater than one – most people working in the field viewed the experiment as the demonstration of ignition as defined by the Lawson ...
A gain greater than one (greater than zero dB), that is, amplification, is the defining property of an active device or circuit, while a passive circuit will have a gain of less than one. [4] The term gain alone is ambiguous, and can refer to the ratio of output to input voltage (voltage gain), current (current gain) or electric power (power ...
Fusion energy gain factor: 2022: 1.54: NIF [286] Discharge time (field reversed configuration) 2016: 3 × 10 −1 s: Princeton Field Reversed Configuration [307] Fusion was not observed. Discharge time is not confinement time. Discharge time (stellarator) 2019 >1 × 10 2 s: Wendelstein 7-X [308] [309] Discharge time (tokamak) 2022 >1 × 10 3 s ...
the amount of energy contained in the final ethanol product; the amount of energy directly consumed to make the ethanol (such as the diesel used in tractors) the quality of the resulting ethanol compared to the quality of refined gasoline; the energy indirectly consumed (in order to make the ethanol processing plant, etc.).

The conversion is based on a Traveling-Wave Direct Energy Converter (TWDEC). A gyrotron converter first guides fusion product ions as a beam into a 10-meter long microwave cavity filled with a 10-tesla magnetic field, where 155 MHz microwaves are generated and converted to a high voltage DC output through rectennas.
