Calibration of electron spectrometer resolution in attosecond streak camera.
We report a new method for determining the energy resolution of time-of-flight spectrometers for detecting photoelectrons produced with attosecond XUV pulses. By measuring the width of the 2s2p autoionization line of helium, we found the resolution of our spectrometer to be approximately 0.6 eV for electrons at 35.5 eV. Furthermore, the resolution in the 10 to 35 eV range was determined by appl...
متن کاملModeling Streak Camera Sweep Speeds
On the OMEGA laser system at the University of Rochester's Laboratory for Laser Energetics (LLE), six P5 10 streak cameras measure the pulse shape of the 60 OMEGA beam lines. These cameras use a photocathode to convert an optical signal into an electron beam. A voltage ramp then sweeps this electron beam across a phosphor screen which is in turn imaged by a CCD. Currently, 120 images of an eigh...
متن کاملStreak Camera for Strong-Field Ionization.
Ionization of an atom or molecule by a strong laser field produces suboptical cycle wave packets whose control has given rise to attosecond science. The final states of the wave packets depend on ionization and deflection by the laser field, which are convoluted in conventional experiments. Here, we demonstrate a technique enabling efficient electron deflection, separate from the field driving ...
متن کاملUse of streak camera for time - resolved
The use of a conventional streak camera for subnanosecond timeresolved fluorimetry is extended to the single-photon counting regime by utilizing intensified readout of the phosphor. The system achieves the usual k e y advantages of photon counting, namely single-photon sensitivity, large dynamic range and shot noise limited statistics, but also permits measurements of lower repetition rate and ...
متن کاملPerformance Comparison of Streak Camera Recording Systems
Performance characteristics of various readout systems coupled to an EGG-AVO streak camera were analyzed and compared to scaling estimates. The purpose of the work was to determine the limits of the streak camera performance and the optimal fielding conditions for the Amador Valley Operations(AV0) streak camera systems. We measured streak camera limitations in spatial resolution and sensitivity...
