A self-colliding particle beam apparatus is capable of increasing stored ion density by a factor 10 and increasing ion confinement time by a factor of 10 to thereby increase the collisional energy between particles. The self-collider comprises essentially a superconducting magnet, an ultra-high vacuum system and an electrostatic stabilizer. The self-collider apparatus can be employed as part of a beam energy multiplier by combining it with an injector, including an ion source, an accelerator and a beam transport system. By increasing the stored ion density by a factor of 10 and by increasing the ion confinement time by a factor of 10, the increase in collisional probability between two particles increases by a factor of 1,000; this is due to the fact that the number of collisions is proportional to (density)2x(confinement time) and therefore 102x10 equals 1,000. If the masses of the particles in the beam are all the same, then the energy increase is up to a factor of 4 as calculated by the formula (1+M1/M2)2.
