Abstract
A TEM sample holder enables simultaneous cooling and RF irradiation of a sample. The sample is suspended in a hole that penetrates through a sample stage formed by a dielectric plate having a lower metallic ground layer and an upper metallic lead. The sample stage is supported by an evacuated hollow tube extending from a cryogenic chamber, such as a liquid nitrogen or helium Dewar. A coaxial conductor extends from an ambient connector through the cryogenic chamber and hollow tube to the sample stage, a center conductor and surrounding metallic shield thereof being in thermal and electrical communication with the metallic lead and metallic ground layer respectively of the sample stage, and the metallic shield being is in direct thermal communication with the cryogenic chamber. The coaxial conductor thereby enables simultaneous cooling and RF irradiation of the sample during TEM measurements. Embodiments include a temperature sensor and heater.
