January 6, 2010

Today was my first day back in the lab from my winter break. I was actually getting better scans after break than I was before break, I'm not sure if the members of the lab did any work on the scope while I was on break. When I first went to approach the tip toward the surface I heard a clicking noise, rather than the usually high pitched buzz, I asked them why it was doing this. Matt Jobbin who uses the same hardware as Annette's scope had switched some settings around and he said that he had forgotten to set them back. He had been messing with the voltages and also he changed the setpoint, which should be set at 2.

The issue that I encountered today was that for some reason my scan window (2000 angstroms) was less than 5 percent of the area that I am able to scan. So my scan window appeared to be very small when it was really rather large. The program XPM pro sometimes switches the gain from 13mV to 100mV. This switch changes the size of the scan window. In order to switch them back I click settings---hardware configuration---gains-and I switch the two gains from 100 to 13mV.

Dr. Loughran I'm not sure you if got my email, however, the current date for the next project Febuary 26/27 happens to be the date of the state championships for swimming and I am currently on two state ranked relays so most likely I will be in indianapolis these days. We need to discuss possible other projects or dates that I could do instead.
