Abstract

In order to do more extensive testing in superconductive materials one must be able to produce superconductive material. For a room temperature superconductor, Yttrium Barium Cupric Oxide, YBa2Cu3O7 is great as an entry level superconductor. However in order to produce YBa2Cu3O7, one must heat it to high temperatures for significant amounts of time. Depending on the stage of firing, the components will be held at a temperature greater than 900°C for between 18 hours to 24 hours. Should the temperature fall below, or creep above, a certain threshold the entire material being heated is wasted. In an effort to sleep in my own bed, and see the sunlight from outside Kettler Hall, an automated system, with proper safety lockouts, must be designed. In order to ensure proper temperature without hands on adjustment, a PSoC, Programmable System on a Chip, is used to detect, collect, and actively control a heating element. To ensure accuracy double correlated sampling is advisable. The signal from a thermocouples produces a significant amount of noise at low temperature, and this noise becomes greater the hotter the thermocouple becomes. Double Correlated Sampling can be used to determine the current signal from the thermocouple as well as the base signal, and subtract the noise off the signal, providing a nice clear signal, for the PSoC to determine an accurate temperature and adjust accordingly.
