 note = {We have investigated laser intensity scaling for accelerated proton energy and attainable electrostatic field using a micro-bubble implosion (MBI). In MBI, the bubble wall protons are subject to volumetric acceleration toward the center due to the spherically symmetric electrostatic force generated by hot electrons filling the bubble. Such an implosion can generate an ultrahigh density proton core of nanometer size on the collapse, which results in an ultrahigh electrostatic field to emit energetic protons in the relativistic regime. Three-dimensional particle-in-cell (PIC) and molecular dynamics (MD) simulations are conducted in a complementary manner. As a result, the underlying physics of MBI is revealed such as bubble-pulsation and ultrahigh energy densities, that are higher by orders of magnitude than, for example, those expected in a fusion-igniting core of inertially confined plasma., 3rd Asia-Pacific Conference on Plasma Physics},
