The injector to be described is a component in the Electron Injector-Linear Accelerator—Condenser Module for illumination used on the variable 100-500kV electron microscope being built at the Radio Corporation of America for the University of Virginia.The injector is an independently powered, autonomous unit, operating at a constant 6kV positive with respect to accelerator potential, thereby making beam current independent of accelerator potential. The injector provides for on-axis ion trapping to prolong filament lifetime, and incorporates a derived Einzel lens for optical integration into the overall illumination system for microscopy. Electrostatic beam deflectors for alignment are an integral part of the apparatus. The entire injector unit is cantilevered off a door for side loading, and is topped with a 4-filament turret released electrically but driven by a self-contained Negator spring motor.

In 1822, from his Conway home in the shadow of New Hampshire's White Mountains, one Dr. Porter surveyed the nation's religious landscape and prophesied, “in half a century there will be no Pagans, Jews, Mohammedans, Unitarians or Methodists.” The prophecy proved false on all counts, but it was most glaringly false in the case of the Methodists. In less than a decade, Porter's home state became the eighth to elect a Methodist governor. Should Porter have fled south into Massachusetts to escape the rising Methodist tide, he would only have been buying time. True, the citizens of Provincetown, Massachusetts, had, in 1795, razed a Methodist meetinghouse and tarred and feathered a Methodist in effigy. By 1851, however, the Methodists boasted a swelling Cape Cod membership, a majority of the church members on Martha's Vineyard, and a governor in the Massachusetts statehouse.
