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.
Dette design kom fra arbejde udført af Philo T. Farnsworth i 1964 - og Robert L. Hirsch i 1967.
En fusorvariant er tidligere blevet foreslået af William Elmore, James L. Tuck og Ken Watson ved Los Alamos National Laboratory men de har aldrig bygget maskinen.
