AFM is down today. A user reported that she could not align the laser on to AFM probe. I checked it and found that the laser vertical was moved too much in one direction. The optical microscope objective lens was adjusted to one limit as well. I am going to contact AFM engineer to check it with him later.
AFM down 9/3/2013 and up 9/9/2013

The AFM has been fixed. You should not change laser position (vertical) too much to find, otherwise, please contact me instead of trying by yourself.
