## x vs pz (Data)¶

*The distribution of pz vs x upstream of the absorber*

*The distribution of pz vs x downstream of the absorber. The downstream muon sample has a more spread-out longitudinal momentum as a result of reverse emittance exchange.*

## x vs pz and density versus average beam radius (MC recon)¶

*The distribution of density of each phase-space contour, as measured with the kernel density estimation technique vs the square-root of contour volume (average beam radius in the one-dimensional longitudinal direction), as measured with the kernel density estimation and the Monte Carlo volume calculation techniques. The distribution is the distribution of the longitudinal coordinate energy (energy with respect to mean energy) of each muon. Longitudinal heating (the expected effect from reverse emittance exchange) is demonstrated as the decrease in density at low average beam radius values.*

*The distribution of density of each phase-space contour, as measured with the kernel density estimation technique vs the fourth-root of contour volume (average beam radius in the four-dimensional transverse direction), as measured with the kernel density estimation and the Monte Carlo volume calculation techniques. The distributions are the distributions of the transverse coordinates x, px, y, py of each muon. Transverse cooling (the expected effect from reverse emittance exchange) is demonstrated as the increase in density at low average beam radius values.*
