NPGS  : FIB Milling

The movie files below show NPGS being used for FIB Milling.  The work was performed by Dr. David C Cox at the Advanced Technology Institute, University of Surrey, UK.

(The movie images appear stretched in the horizontal direction because the movies are acquired using the electron beam in a dual e-beam / ion beam microscope and during milling the sample is positioned normal to the ion beam, but is at a large angle relative to the e-beam. The thumbnail images on the Sample Pictures page show the true aspect ratio as seen when the sample is normal to the e-beam.)

(The movies appear choppy because of a mismatch between the frame averaging of the microscope and the frame rate of the movie capture.)
