|MagE CCD System
Inside the housing, the CCD signals are brought out to the preamp board using a wire bundle that follows the same path as the cold strap (to minimize blocking the optical beam). The wire bundle has a standard 37-pin micro-D connector. A rigid-flex preamp board is inside the vacuum housing, and brings the signals out on a flex cable to a hermetic connector.
The CCD control electronics box is attached to the side of the dewar (see photo). The CCD controller is a compact two-channel digital signal processor based system, capable of both high-speed and slow-scan readout.
The CCD is cooled to a nominal -110 C. Lab tests show that read noise is about 3.2 e-/pixel.
Readout time at 10 µs/pixel is approximately 20 seconds, with 1×1 binning.
* add some images from MagE
* add CAD drawing of the dewar
* add lab test results
At the start of the project, we experimented with reducing the size of the ccd package (by milling away parts of it). Some photos of the results are here.
