Week+of+1-28-2013

1-28-2013 I went into the lab on this day and due to a miscommunication, Matt wasn't there. I wasn't sure of what to do since I had no instructions or circuit diagrams to work with. I spent some time cleaning up around my work station but after a short time I just went home. Unfortunately, I was unable to accomplish any science while in the lab. 1-31-2013 I came in today and began scanning with the new scope that Matt and the new grad student Ashley rebuilt and that I had worked on some of the designs for as detailed here: Week of 12-3-2012. The goal of today was to test out this new scope and make sure that it could indeed approach and tunnel using the same electronics that the scope I experimented with last semester used. Jolai and I scanned a sample of plain, unannealed gold that had been sitting out for a few days. We did not expect to obtain any sort of high quality results. 1-31-2013AA-2000 Angstroms, 100 ms/line, A/D:8 1-31-2013AB-2000 Angstroms, 100 ms/line, A/D:8 1-31-2013AC-2000 Angstroms, 100 ms/line, A/D:8 1-31-2013AD-2000 Angstroms, 100 ms/line, A/D: 8 1-31-2013AE-2000 Angstroms, 100 ms/line, A/D:8, Scanned in the Y-Direction 1-31-2013AF-2000 Angstroms, 100 ms/line, A/D:8 1-31-2013AG: 2000 Angstroms, 100 ms/line, A/D: 8 1-31-2013AH- 2000 Angstroms, 100 ms/line, A/D:8 1-31-2013AI-2000 Angstroms, 100 ms/line, A/D:8, Scaned in the Y-Direction 1-31-2013AJ-500 Angstroms, 100 ms/line A/D Gain:16 I plan on doing a more in-depth analysis of how the scope works next week which include pictures of the finished product. The major success of today is that we were able to show that the new scope is able to scan as these results show clearly the surface of gold. They are mostly consistent with the images I have obtained in the past of unannealed, plain gold. This scope is very similar in its design to the one that will be using the Peltier and that I will continue my heating experiment on. Because of their similarities, the success on this scope gives us reason to believe that the design for our scope will provide us consistent and plentiful results. We will also of course be using a better sample.
