just think the conditions of stars/the sun

Hotter than the sun. The sun has an enormous gravity pushing things along. To compensate we use more heat.

I thought we used magnetrons and such, and the excessive heat was due to current inefficiency and control of the fusion process in containing the heat and it building up higher and higher.

The heat is needed so atoms collide enough to fuse without the high pressure inside a star. The trick is keeping the reaction going.
