Evaluation of emulsions and other recording media for 100 and 1000kV electron microscopes

Electron Diffraction of Wet Phospholipid Bilayers

“…Two methods were used to reduce the radiation damage: (i) The beam current was kept to a minimum by using an extremely small condenser aperture (10 ,um); and (ii) The diffraction patterns were recorded on very sensitive No-Screen X-ray films. This film has been shown to be 17 times more sensitive than ordinary electron image plates (13). Therefore, the specimen radiation damage is greatly reduced.…”

Electron diffraction from single, fully-hydrated, ox-liver catalase microcrystals

“…Because of this radiation sensitivity the crystals were never imaged beforehand. Exposures well below the cited limit were guaranteed by use of Kodak X-ray film which has been found to be significantly more sensitive than electron image plates to electrons at several accelerating voltages (Matricardi, Wray & Parsons, 1972).…”

The interpretation of quasi-kinematical single-crystal electron diffraction intensity data from paraffins

“…Radiation damage was further minimized by liquid nitrogen cooling of the specimen stage. For all experiments, diffraction patterns were recorded on Kodak no-screen X-ray film which is 17-fold more sensitive than electron image plates at 100 kV (Matricardi, Wray & Parsons, 1972). Diffraction spacings were calibrated by simultaneous recording of single-crystal paraffin and Au ° powder diffraction patterns from a region of the specimen grid upon which a thin film of Au ° had been evaporated.…”
