Novel emergent phenomena are expected to occur under conditions exceeding theQED critical electric field, where the vacuum becomes unstable toelectron-positron pair production. The required intensity to reach this regime,$\sim10^{29}\,\mathrm{Wcm^{-2}}$, cannot be achieved even with the most intenselasers now being planned/constructed without a sizeable Lorentz boost providedby interactions with ultrarelativistic particles. Seeded laser-laser collisionsmay access this strong-field QED regime at laser intensities as low as$\sim10^{24}\,\mathrm{Wcm^{-2}}$. Counterpropagating e-beam--laser interactionsexceed the QED critical field at still lower intensities($\sim10^{20}\,\mathrm{Wcm^{-2}}$ at $\sim10\,\mathrm{GeV}$). Novel emergentphenomena are predicted to occur in the "QED plasma regime", where strong-fieldquantum and collective plasma effects play off one another. Here the electronbeam density becomes a decisive factor. Thus, the challenge is not just toexceed the QED critical field, but to do so with high quality, approachingsolid-density electron beams. Even though laser wakefield accelerators (LWFA)represent a very promising research field, conventional accelerators stillprovide orders of magnitude higher charge densities at energies$\gtrsim10\,\mathrm{GeV}$. Co-location of extremely dense and highly energeticelectron beams with a multi-petawatt laser system would therefore enableseminal research opportunities in high-field physics and laboratoryastrophysics. This white paper elucidates the potential scientific impact ofmulti-beam capabilities that combine a multi-PW optical laser,high-energy/density electron beam, and high-intensity x rays and outlines howto achieve such capabilities by co-locating a 3-10 PW laser with astate-of-the-art linear accelerator.
