The production of x-radiation
WebbWe also studied the effects of background electron density from previous discharges. We find that X-radiation and γ-radiation are enhanced when the on-axis air density is reduced by more than ∼25%. WebbBremsstrahlung is electromagnetic radiation similar to x-radiation. It is emitted by a charged particle as it decelerates in a series of collisions with atomic particles. This mechanism is illustrated in Fig. 1.25, where a beta particle traveling through matter approaches a nucleus and is deflected by it.This deflection causes a deceleration of the …
