This proposal describes research designed to improve the                   technique of elemental analysis done by electron microscopy at                  liquid helium temperatures.  The advantage to utilizing such low                temperatures is a reduction in radiation damage from the beam of                the electron microscope which minimizes the resulting mass loss                 from the specimen.  This result is an important step in the                     development of microanalytical techniques for biological                        specimens.  In this project the rates of radiation damage for                   various materials and substrates will be determined (by the use                 of energy loss spectroscopy) to optimize the specimen                           environment.  Elemental label compounds will be tested for                      detectibility and position stability at liquid helium                           temperatures.  Finally, to make the operation of the quantitative               microscope more efficient and available to more users, the                      programs for the system will be moved to a more user-friendly                   computer.
