A single-shot phase-tagged time-of-flight-photoelectron emission microscope has recently been developed to investigate and control carrier-envelope phase (CEP) effects on tailored plasmonic nanostructures. First experiments measuring the CEP dependence on single gold nanoparticles on gold plane (NPOP) have been performed with 10 kHz few-cycle laser pulses via a multiphoton photoemission process. We report the results from calculations and observation of a CEP feature from the NPOP sample as well as the challenges of the experiments. We also address the possible solutions to improve the plasmonic sample quality and design for probing and control the plasmonic dynamics via the CEP effect. The experimental setup provides a versatile tool for both spatial-resolved and energy-resolved studies of the attosecond control of electrons in plasmonic nanostructures.
