acceleration voltage : ウィキペディア英語版
acceleration voltage
In accelerator physics, the term acceleration voltage means the effective voltage surpassed by a charged particle along a defined straight line. If not specified further, the term is likely to refer to the ''longitudinal effective acceleration voltage'' V_\parallel.
The acceleration voltage is an important quantity for the design of microwave cavities for particle accelerators. See also shunt impedance.
For the special case of an electrostatic field that is surpassed by a particle, the acceleration voltage is directly given by integrating the electric field along its path. The following considerations are generalized for time-dependent fields.
== Longitudinal voltage ==

The longitudinal effective acceleration voltage is given by the kinetic energy gain experienced by a particle with velocity \beta c along a defined straight path (path integral of the longitudinal Lorentz forces) divided by its charge,〔
V_\parallel(\beta) = \frac 1 q \vec e_s \cdot \int \vec F_L(s,t) \,\mathrms = \frac 1 q \vec e_s \cdot \int \vec F_L(s, t = \frac) \,\mathrm d s .
For resonant structures, e.g. SRF cavities, this may be expressed as a Fourier integral, because the fields \vec E,\vec B, and the resulting Lorentz force \vec F_L, are proportional to \exp(i \omega t) (eigenmodes)
V_\parallel(\beta) = \frac \vec e_s \cdot \int \vec F_L(s) \exp\left(i \frac s\right)\,\mathrm d s = \frac \vec e_s \cdot \int \vec F_L(s) \exp\left(i k_\beta s\right)\,\mathrm d s with k_\beta = \frac
Since the particles kinetic energy can only be changed by electric fields, this reduces to
V_\parallel(\beta) = \int E_s(s) \exp\left(i k_\beta s\right)\,\mathrm d s
