摘要:
An apparatus is described for irradiation of biological and chemical materials in vacuum with electron beams of intensities varying between 10−6and 10−10coulomb per square centimeter and of energies ranging between 10 and 100 kv. The beam can be easily adjusted and scanned for homogeneity. Through an arrangement of stops, a large number of targets can be conveniently irradiated in a relatively short period.
