We propose and investigate a novel scheme for generating high-pressure shocks which is much more efficient than the laser-based schemes known so far. In the proposed scheme, the shock is generated in a dense target by the impact of a fast projectile driven by the laser-induced cavity pressure acceleration (LICPA) mechanism. Using two-dimensional hydrodynamic simulations and the measurements performed at the kilojoule PALS laser facility it is shown that in the LICPA-driven collider the laser-to-shock energy conversion efficiency can reach a very high value ∼15–20 % and, as a result, the shock pressure ∼0.5–1 Gbar can be produced using lasers of energy 60.5 kJ. On the other hand, the pressures in the multi-Mbar range could be produced in this collider with low-energy (∼10 J) lasers available on the market. It would open up the possibility of conducting research in high energy-density science also in small, university-class laboratories.
