This view of an assembled Optical Transition Radiation (OTR) beam viewer shows a number of unique features:
The first is that the camera is mounted at floor level. This makes shielding against radiation damage easy. Blocks of lead or concrete are simply stacked on the floor next to the camera.
All optical components are mounted to a four rod track system for ease of adjustments.
We normally use standard conflat crosses, but can provide other shapes and flange types.
View screens are moved into the beam by pneumatic cylinders and returned by springs in the cylinders.
A solid state lamp ring illuminates the viewer for calibration and alignment purposes. Black neoprene bellows cover all components and are easy to move aside for access to the camera, lenses, and filters.
This example has three Neutral Density (ND) filters that are remotely controlled. These element are 0.5, 1, and 2 providing attenuation of up to 5000. A 1 inch thick leaded glass radiation shield protects the camera from the radiation sources above. A number of different cameras are available including both CCD and vidicon as well as RS170 format or CCIR. Shown is the Cohu series 4900.
At the very bottom of the track system is an elastic vibration damper contacting the floor. Complete controls interfaces are available to integrate directly into your control system.
