February+14-15

February 14th:

-Just a sample of graphite on tape with the portable AFM. -The plan is to scan it today and expose it overnight to the Polonium-210 -There were several bouts of interference, but not too many that completely halted the scan -Mostly the interference was in small patches -I did change the tip before scanning and it may have contributed to the strange images



February 15th:

-I scanned the same sample as yesterday, the graphite on scotch tape, on the portable AFM -it was exposed from 6:00 p.m. yesterday to 3:45 p.m. today -the interference is more pronounced than yesterday, and this likely has to do with the exposure -the interference seems to be in patches, with either one patch in a scan or several
