Query: Electron response to radiation under linear acceleration: classical, QED
  and accelerated frame predictions   A model detector undergoing constant, infinite-duration acceleration
converges to an equilibrium state described by the Hawking-Unruh temperature
$T_a=(a/2\pi)(\hbar/c)$. To relate this prediction to experimental observables,
a point-like charged particle, such as an electron, is considered in place of
the model detector. Instead of the detector's internal degree of freedom, the
electron's low-momentum fluctuations in the plane transverse to the
acceleration provide a degree of freedom and observables which are compatible
with the symmetry and thermalize by interaction with the radiation field.
General arguments in the accelerated frame suggest thermalization and a
fluctuation-dissipation relation but leave underdetermined the magnitude of
either the fluctuation or the dissipation. Lab frame analysis reproduces the
radiation losses, described by the classical Lorentz-Abraham-Dirac equation,
and reveals a classical stochastic force. We derive the fluctuation-dissipation
relation between the radiation losses and stochastic force as well as
equipartitation $\langle p_\perp^2\rangle = 2mT_a$ from classical
electrodynamics alone. The derivation uses only straightforward statistical
definitions to obtain the dissipation and fluctuation dynamics. Since high
accelerations are necessary for these dynamics to become important, we compare
classical results for the relaxation and diffusion times to strong-field
quantum electrodynamics results. We find that experimental realization will
require development of more precise observables. Even wakefield accelerators,
which offer the largest linear accelerations available in the lab, will require
improvement over current technology as well as high statistics to distinguish
an effect.
