A Cryogenic CMOS-based Control System for Testing Superconductor Electronics P.C. van Niekerk Department of Electrical and Electronic Engineering University of Stellenbosch Private Bag X1, 7602 Matieland, South Africa Thesis: M.Sc.Eng. (E&E) March 2008 A complete control system, with accompanying software, is designed to interface superconductive digital and sensory circuits for use in cryogenic vacuumed environments. It acts as an inter-mediator between superconductor electronics and room temperature electronics for research purposes. In order to facilitate low bit-error rate communications with superconductive electronics, the system is designed to have ultra low-noise current and voltage sources for transmitting data to superconductor electronics. Very high sensitivity voltage inputs are also implemented for data extraction from superconductor electronics. It implements both digital as well as analog design components, including ADC and DAC devices. The data is transmitted via a USB cable connection at 1Mbaud to a computer where the data is processed by specially designed software and graphically displayed for user interfaced research. Extensive research is done on the electronic components, such as CMOS devices, for functioning in an average temperature of 70 Kelvin inside cryogenic environments. This is done to reduce the thermal noise and heat transfer to superconductor electronics. An integrated temperature control system also ensures a stable environment for the electronics to operate at 70 K. 2008-08-12T09:26:42Z 2010-06-01T08:46:33Z 2008-08-12T09:26:42Z 2010-06-01T08:46:33Z 2008-03 Thesis http://hdl.handle.net/10019.1/2345 en University of Stellenbosch application/pdf Stellenbosch : University of Stellenbosch |
