            Abstract : 
R.K. Hursh1 describes a porcelain made by casting to produce a satisfactory vacuum tube for a betatron. The tube is toroidal in form with two tubular arms attached to which glass connections are fused for the sealed-in electrical leads. The interior of the tube is permanently sealed off and holds a high vacuum.
