Abstract
A prototype of scientific CCD detector system is designed, implemented and tested for the extreme environment in Antarctic, including clocks and biases driver for CCD chip, video pre-amplifier, video sampling circuit and ultra-low noise power. The low temperature influence is fully considered in the electronics design. Low noise readout system with CCD47-20 is tested, and the readout noise is as low as 5e- when the CCD readout speed is 100kpixs/s. We simulated the extreme low temperature environment of Antarctic to test the system, and verified that the system has the ability of long-term working in the extreme low temperature environment as low as -80°C.
