Query: Bi-dipole wave: optimum for attaining extreme regimes at matter-light
  colliders   The collision of accelerated electrons with high-intensity laser pulses
provides a way for triggering and studying the processes of strong-field
quantum electrodynamics by means of reaching high values of the $\chi$
parameter, the parameter that quantifies electron's acceleration in its rest
frame. For a given electrons' energy $\varepsilon$ and a given peak,
cycle-averaged power $P$ of the laser radiation the maximal value of $\chi$
depends on the way the radiation is focused to cause the acceleration. We
determine and describe the optimal focusing geometry for reaching the highest
possible value $\chi \approx 5.28 \left(\varepsilon / (\text{1~GeV})
\right)\left(P/(\text{1~PW})\right)^{1/2}\left(\lambda/(\text{1~}\mu\text{m})\right)^{-1}$,
where $\lambda$ is the laser wavelength. We propose an experimental setup that
exploits the bi-dipole wave and assess this setup for the parameters relevant
to current and upcoming experimental capabilities.
