Week+of+Nov+24


 * Monday, November 24**

Today, I really had a hard time getting an image. First, I could not see anything with the gold surface so I changed to the previous sample to just check. And then I could not get any images either. Later, it turned out to be that the machine did not work. Even though I pushed the approach/withdraw button, it did not move. Dr.L suggested to clean up the surface of the thing because we could see the finger prints. In addition, I tried to clean the machine itself. I made a new tip and I think I made some kind of progress of making a sharp tip. I could visibly see the sharpness of the tip this time. After all that, I could finally see some images coming! :)
