APT-12_The 2nd stage is done under a stereo microscope
APT-15_Looks just like the Arup Building, the Department of Engineering Science Building of Oxford.
APT-10_The sample preparation is manual and requires time
APT-01_The Local Electrod Atom Probe (LEAP) 3000X
APT-02_A closer look
APT-03_The three vacuum chambers, analysis is done under Utral High Vacuum (3x10^-11 mBar) and very low temperature (30 kelvin)
APT-04_Things are more interesting when looked from behind
APT-05_Looking down the Load Lock door where samples and local electrode can be loaded into the high vacuum system
APT-08_The Buffer
APT-07_The Buffer, where samples and local electrode are stored under very high vacuum (10^-9 mBar) before analysis
APT-06_Side look of the Load Lock, beneath is a gate valve (the rectangular thing) leading to the Buffer
APT-11_Setup for the second stage electropolishing of samples to make a very thin needle
APT-09_Setup of the first stage sample preparation for atom probe
APT-13_Finally we are seeing ionised atoms from a steel sample hitting detectors
APT-14_The colours represent atoms of differnt elements, notice the green Nickle (Ni) atoms clusters
