Caught the solid->liquid->gas transition in this crystalline beam simulation.  I also corrected my initial conditions since the last one, so you can see some "adiabatic shrinkage" while it's still accelerating in the solid state.  BUT it still melts, so I think I'm not following the stable region correctly for higher energies.   #accelerators #physics <p><video src='posts/202607/post-20260716-152847-a.mp4' loading='lazy' preload='metadata' controls></video></p>
