Quick Day


Today was cut short for several reasons. The wildfires in Goleta have left the university and the city prone to frequent power outtages. Consequently, both of our "batches" of YBCO are going to be in their respective furnaces for the rest of the day.

Our first batch is finishing up its second annealing cycle. The Meissner effect left something to be desired, so another round of oxygen was attempted to remove any remaining impurities.

Our second batch is going through its first heating cycle (48 hours at 940 degrees C). With the 4th of July holiday, we had to cut the day short and pick up next week
