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.

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.

The HPD-TA (Temporal Analyzer) is a high-performance digital data

acquisition and control system specifically designed to read out im-

ages from the Hamamatsu streak camera’s phosphor screen. It ena-

bles precise, quantitative acquisition and pre-analysis of two dimen-

sional 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 grab-

ber board that can support real-time data transfer.

The HPD-TA allows the remote control of the C5680 via GPIB in-

terface. The entire system is controlled through a powerful but

userfriendly software application that runs on a Microsoft Win-

dows platform.
