, McDaniel was recruited by
Georgia Tech Research Institute director
James Boyd to return to Georgia Tech as an assistant professor. He received appointments in both the School of Physics and the School of Electrical Engineering.
Apart from his work as a physicist, McDaniel was known to be an avid reader of both fiction and classics as well as an expert on the histories of great military conflicts and battles.
Drift tube
In 1964, Earl began construction of a "drift tube" with the help of mechanical engineering student, Dan Albritton. Using this drift tube the pair revolutionized the field of ion transport. Their publication "Mobilities of Mass-Identified H
3+ and H
+ Ions in Hydrogen" was chosen as one of the top 100 papers ever published in the journal ''Physical Review''.
Publications
Aside from several popular research publications, McDaniel also authored or edited 8 books. Among these, the most notable were "Collision Phenomena in Ionized Gases,"
“Transport Properties of Ions in Gases,” "Atomic Collisions: Electron and Photon Projectiles,” and “Atomic Collisions: Heavy Particle Projectiles.” These books were published in several countries and translated into multiple languages.
