What is the main cause of fusion ignition???

Question

Thanks for the detail...tom science

Answer 1

A thermonuclear plasma is defined as having "ignited" when the fusion burn becomes self-sustaining - requiring no further external power input to keep it hot enough to continue burning until the fuel is depleted or, if fuel is continuously added, indefinitely. It occurs when such self-heating is at least as great as radiated heat loss. What "causes" this is a system capable of confining the plasma at sufficiently high density and temperature, and an initial external source of energy able to get things going.

Answer 2

There are 5 ways to heat a plasma
1) Ohmic heating: this is caused by current traveling through resistance
2) Wave heating: we use E&M waves to heat plasma
3) Neutral Beam injection: we accelerate particles to high energy and then inject them into the plasma
4) Pressure Heating: PV=nkT, as pressure increases so will Tempurature
and once we ignite the plasma we can use
5)Fusion product heating: energy released from one fusion event can be used to heat the plasma so more fusion can occur

Answer 3

Exceptional heat causes Fusion.

Think Stars.

Answer 4

And extream heat is caused by extream sex! lol no really it starts when mass comes together with other mass and starts to "rub" each other more and more.

Answer 5

We would like to know if we did know it would represent fuel forever.
