Claim 10:
11. A microscope control system for measuring electron dose in a sample with a transmission electron microscope (TEM), the system comprising:
a processor configured for:
taking multiple measurements of the area of an electron beam of the TEM and the amount of current produced by the electron beam of the TEM,
wherein the TEM has different condenser lens settings for the multiple measurements of the area of the electron beam and the amount of current produced by the electron beam;

using the electron beam to excite the sample during an experiment performed on the sample using the TEM, wherein the TEM is set with particular condenser lens settings;
determining a beam area and a beam current of the electron beam used to excite the sample during the experiment for the particular condenser lens settings of the TEM based on the multiple measurements of the area of the electron beam and the amount of current produced by the electron beam; and
measuring an electron dose rate on the sample during the experiment based on the determined beam area and the determined beam current for the particular condenser lens settings of the TEM.
