En hjemmelavet fusor.

En fusor er et apparat, som anvender et elektrisk felt til at opvarme ioner til kernefusion betingelser. Maskinen inducerer en spænding mellem to metalbure, i et vakuum. Positive ioner falder gennem dette spændingsfald, hvilket øger ionhastigheden. Hvis ionerne kolliderer i centrum, kan de fusionere.

En Farnsworth-Hirsch fusor er den mest almindelige fusortype.[1] Dette design kom fra arbejde udført af Philo T. Farnsworth i 1964 - og Robert L. Hirsch i 1967.[2][3] En fusorvariant er tidligere blevet foreslået af William Elmore, James L. Tuck og Ken Watson ved Los Alamos National Laboratory[4] men de har aldrig bygget maskinen.

Fusorer er blevet bygget af forskellige institutioner. Disse inkluderer akademiske institutioner såsom University of Wisconsin–Madison,[5], Massachusetts Institute of Technology[6] og myndighedsorganer, såsom Atomic Energy Organization of Iran og Turkish Atomic Energy Authority.[7][8] Fusorer er også blevet udviklet kommercielt, som neutronkilder af DaimlerChrysler Aerospace[9] og som en metode til at generere medicinske isotoper.[10][11][12] Fusorer er og blevet meget populære for hobbyister og amatører. Et stigende antal amatører har udført kernefusion ved at anvende simple fusormaskiner.[13][14][15][16][17][18]
