Measurements Ranging From X-Ray to Near Infrared With a Temporal Resolution of 2 ps The streak camera is an ultra high-speed detector which captures light emission phenomena occurring in extremely short time periods. Not only can the streak camera measure intensity variations with superb temporal resolution, but it can also be used for simultaneous measurement of the spatial (or spectral) distribution. The C5680 Streak Camera Series is a universal streak camera which incorporates all of the specialized technology and expertise HAMAMATSU has acquired in over 20 years of research. The streak tubes are manufactured on a regular production schedule at Hamamatsu to provide consistency and reliability. Special requests and custom designs are also available.

APPLICATIONS

Measurement of electron bunch for synchrotron and LINAC applications Research involving X-ray lasers, free electron lasers, and various other types of pulsed lasers Plasma light emission, radiation, laser ablasion, combustion and explosions Fluorescence lifetime measurement, transient absorption measurement, time-resolved raman spectroscopy Optical soliton communications, response measurement with quantum devices Lidar Thomson scattering, laser distance measurement Universal Streak Camera C5680 Series

FEATURES

• Temporal resolution of within 2 ps A temporal resolution of 2 ps is achieved for both synchroscan and single shot.
• Ultra-high sensitivity (detection of single photons) Several plug-in module, operating mode. Accommodates a diverse range of experimental setups from single light emitting phenomena to high-speed repeated phenomena in the GHz. Can be used in X-ray to near infrared fields By selecting the appropriate streak tube (light sensor), the C5680 can be used in a wide range of measurement appli- cations, from X-rays to near infrared light. Simultaneous measurement of light intensity on temporal and spatial (wavelength) axes Spectrograph can be placed in front of the streak camera, to convert the spatial axis to a wavelength axis. This enables changes in the light intensity to be measured over various wavelength (time-resolved spectroscopy). The streak tube converts light into electrons which are then multiplied by an electron multiplier. This enables detection of extremely faint light (at the single-photon level). (See photon counting integration principle) IEEE-488 (GP-IB) control Computer control enables remote control and advanced measurements to be performed out using very simple op- eration. Diverse selection of peripheral equipment A full lineup of peripheral devices is available, including spectroscopes, optical trigger heads, and expansion units. OPERATING PRINCIPLE The light pulse to be measured is projected onto the slit and is focused by the lens into an optical image on the photocathode of the streak tube. Changing the temporal and spatial offset slightly each time, four light pulses, each with a different light itensity, are introduced through the slit and conducted to the photocathode. Here, the photons are converted into a number of electrons proportional to the intensity of the incident light. The four light pulses are converted sequentially to electrons which are then accelerated and conducted towards the photocathode. As the group of electrons created from the four light pulses passes between a pair of sweep electrodes, a high voltage is applied (see above), resulting in a high-speed sweep (the elec- trons are swept in the direction from top to bottom). The elec- trons are deflected at different times, and at slightly different angles in the perpendicular direction, and are then conducted to the MCP (micro-channel plate). As the electrons pass the MCP, they are multiplied several thousands of times and are then bombarded against the phos- phorscreen, where they are converted back into light. The fluorescence image corresponding to the first incident light pulse is positioned at the top of the phosphor screen, follo- wedby the others, with images proceeding in descending or- der; inother words, the axis in the perpendicular direction on the phosphor screen serves as the temporal axis. The bright- nesses ofthe various fluorescence images are proportional to theintensities of the corresponding incident light pulses. The positions in the horizontal direction on the phosphor screen correspond to the positions of the incident light in the horizon- tal direction. THE PRINCIPLE OF PHOTON COUNTING INTEGRATION Photoelectrons given off from the photocathode of the streak tube are multiplied at a high integration rate by the MCP, and one photoelectron is counted as one intensity point on the phosphor screen. A threshold value is then used with this pho- toelectron image to clearly separate out noise. The operating principle of the streak camera Positions in the photoelectron image which are above the threshold value are detected and are integrated in the memory, enabling noise to be eliminated completely. This makes it possi- ble to achieve data measurements with a high dynamic range and high S/N.
