Project Description

AXIS-NV: High Dynamic Range Streak Camera

AXIS-NV is used for time-resolved spectroscopy of subnanosecond events in the visible and IR range. Its wide aperture allows to streak a 1000 point image with a time resolution of 10-150 picosecond with an extremely high dynamic range.

AXIS-NV SPECIFICATIONS

STREAK TUBE

This streak camera uses a P510 PHOTONIS streak tube built according to high quality standards and features:

  • 10-50 picosecond time resolution
  • High spatial resolution
  • Wide slit (35mm x 5mm)
  • Ruggedized for harsh environment

It can be built with different cathodes and matched with the experiment for optimal throughput:

OPERATION MODES

streak camera-normal-mode Normal sweep
The sweep crosses the whole screen and ends outside.
streak camera-timing-mode Timing mode
The sweep always remains in the screen. It is used to synchronize the streak camera to the experiment.
streak camera-focus-mode Focus mode
The slit image is positioned at the center of the screen. The sweep trigger is disabled. This mode is used to align the experimental setup and to adjust the incident light level.

INTERNAL COMPUTER and SOFTWARE

AXIS-NV is an all-in-one system that is operated locally by connecting a monitor, a keyboard and a mouse.

It comes with an internal computer that controls the streak tube supplies, the sweep circuits, monitors voltage stability, performs different self tests and safety checks. It can also control other optional peripherals via the USB port (a laser system, for example).

All required software comes pre-installed on the system. It is used to:

  • Control whole system and acquire images
  • Control the laser system (optional)
  • Plot lineouts along time axis or space axis
  • save image in different formats

Remote control over Gigabit Ethernet :

  • “Windows Remote Desktop”
  • Web base GUI
  • High level device servers (TANGO, OPC, etc…) are available.
