Abstract
Thin hemispherical glass windows of aluminosilicate glass (Corning No. 1720) have been constructed by means of a simple furnace blowing operation and attached to 4.2 cm diam cylindrical sections of the same glass. The hemispherical end windows of the resulting chamber have 2.1 cm radii, are less than 0.025 mm thick, and withstand a pressure difference of 1 atm from inside to outside. Such thin end windows should be useful in the observation of nuclear or optical scattering from gases where it is desirable to minimize effects from the windows of the vessel containing the gas.
