Use of streak camera for time - resolved
نویسنده
چکیده
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 faster time response phenomena, in regimes inaccessible to microchannel plate photomultiplier instrumentation. Pile-up and problems associated with the slow decay and non-uniformity of the response and readout of the streak camera phosphor are discussed.

Time-resolved measurements from speckle interferometry.
We present time-resolved measurements by speckle interferometry of the light scattered by a liquid medium. Measurements were performed by use of reflectance geometry and are compared with results obtained in the same conditions with a femtosecond laser and a streak camera. The setup was also tested in vivo on the forearm of a human volunteer to demonstrate the potential utility of such a setup ...
متن کاملPlasma Wakefield Acceleration of an Intense Positron Beam: Correlation between Time-resolved and Time- Integrated Energy Diagnostics
The E162 experiment at the Stanford Linear Accelerator Center was the first experiment in which a positron beam gained energy in a plasma wakefield accelerator [1]. A single positron bunch both excited (gave energy to) and witnessed (extracted energy from) the plasma wakefield. The energy dynamics within the single positron bunch were measured in a dispersive section of the beamline with both t...
متن کاملA compact streak camera for 150 fs time resolved measurement of bright pulses in ultrafast electron diffraction.
We have developed a compact streak camera suitable for measuring the duration of highly charged subrelativistic femtosecond electron bunches with an energy bandwidth in the order of 0.1%, as frequently used in ultrafast electron diffraction (UED) experiments for the investigation of ultrafast structural dynamics. The device operates in accumulation mode with 50 fs shot-to-shot timing jitter, an...

We report the cell biological applications of a recently developed multiphoton fluorescence lifetime imaging microscopy system using a streak camera (StreakFLIM). The system was calibrated with standard fluorophore specimens and was shown to have high accuracy and reproducibility. We demonstrate the applicability of this instrument in living cells for measuring the effects of protein targeting ...
متن کاملExact forward scattering of a CO2 laser beam from a relativistic plasma wave by time resolved frequency mixing in AgGaS2
In the UCLA plasma beat wave accelerator, a high intensity two frequency CO2 laser ~l1510.6 mm, l2510.3 mm! is used to drive a large amplitude relativistic plasma wave. The plasma wave acts as a moving phase grating and scatters the incident pump waves into Stokes and anti-Stokes sidebands ~v12vp , v21vp!. The observation of these sidebands in the forward direction confirms the presence of the ...
