Query: On-Shot Characterization of Single Plasma Mirror Temporal Contrast
  Improvement   We report on the setup and commissioning of a compact recollimating single
plasma mirror for temporal contrast enhancement at the Draco 150 TW laser
during laser-proton acceleration experiments. The temporal contrast with and
without plasma mirror is characterized single-shot by means of self-referenced
spectral interferometry with extended time excursion (SRSI-ETE) at
unprecedented dynamic and temporal range. This allows for the first single-shot
measurement of the plasma mirror trigger point, which is interesting for the
quantitative investigation of the complex pre-plasma formation process at the
surface of the target used for proton acceleration. As a demonstration of high
contrast laser plasma interaction we present proton acceleration results with
ultra-thin liquid crystal targets of ~ 1 $\mu$m down to 10 nm thickness. Focus
scans of different target thicknesses show that highest proton energies are
reached for the thinnest targets at best focus. This indicates that the
contrast enhancement is effective such that the acceleration process is not
limited by target pre-expansion induced by laser light preceding the main laser
pulse.
