Universal Streak Camera C5680 Series
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 * 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 synchrotron and LINAC applications
FEATURES
* Temporal resolution of within 2 ps
A temporal resolution of 2 ps is achieved for both synchroscan and single shot.
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 electrons are swept in the direction from top to bottom). The electrons 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 phosphorscreen, 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, followedby the others, with images proceeding in descending order; inother words, the axis in the perpendicular direction on the phosphor screen serves as the temporal axis. The brightnesses 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 horizontal direction.
* 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 applications, 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).
* Ultra-high sensitivity (detection of single photons)
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)
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 photoelectron image to clearly separate out noise.
Separation of Photoelectron Image and Noise Photon Counting Integration
* IEEE-488 (GP-IB) control
Computer control enables remote control and advanced measurements to be performed out using very simple operation.
* Diverse selection of peripheral equipment
A full lineup of peripheral devices is available, including spectroscopes, optical trigger heads, and expansion units.

Time Space
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 possible to achieve data measurements with a high dynamic range and high S/N.
MCP (which multiplies electrons)
The intensity of the incident light can be read from the brightness of the phosphor screen, and the time and space from the position of the phosphor screen.

4 General Outline
The HPD-TA (Temporal Analyzer) is a high-performance digital data acquisition and control system specifically designed to read out images from the Hamamatsu streak camera's phosphor screen. It enables precise, quantitative acquisition and pre-analysis of two dimensional streak data that includes photon counting plus a full range of data correction and calibration possibilities. It possible to select the best camera for a given streak configuration and application. The camera is connected to an IBM-compatible PC/AT via a frame grabber board that can support real-time data transfer. The HPD-TA allows the remote control of the C5680 via GPIB interface. The entire system is controlled through a powerful but userfriendly software application that runs on a Microsoft Windows platform. * A read out system based on the Macintosh(R) computer is also available. Please consult with our sales office for more details.
