'''Linear induction accelerators''' utilize ferrite-loaded, non-resonant [[Electromagnetic_inductionElectromagnetic induction|magnetic induction]] cavities. Each cavity can be thought of as two large washer-shaped disks connected by an outer cylindrical tube. Between the disks is a ferrite toroid. A voltage pulse applied between the two disks causes an increasing magnetic field which inductively couples power into the charged particle beam.<ref>

}}</ref> Linear induction accelerators are capable of accelerating very high beam currents (>1000 A) in a single short pulse. They have been used to generate X-rays for flash radiography (e.g. [[Dual-Axis_Radiographic_Hydrodynamic_Test_FacilityAxis Radiographic Hydrodynamic Test Facility|DARHT]] at [[LANL]]), and have been considered as particle injectors for [[magnetic confinement fusion]] and as drivers for [[free electron laser]]s. A compact version of a linear induction accelerator, the [[dielectric wall accelerator]], has been proposed as a proton accelerator for medical [[proton therapy]].
