Abstract: A Bernas ion source having a shield is disclosed. The shield is disposed between the distal portion of the filament and the first end of the chamber and serves to confine the plasma to the region between the shield and the second end of the chamber. The shield may be electrically connected to the negative leg of the filament so as to be the most negatively biased component in the chamber. In other embodiments, the shield may be electrically floating. In this embodiment, the shield may self-bias. The shield is typically made of a refractory metal. The use of the shield may reduce back heating of the filament by the plasma and reduce the possibility for thermal runaway. This may allow denser plasmas to be generated within the chamber.

Abstract: A method for homogenizing glass includes the method: providing a cylindrical blank composed of the glass having a cylindrical outer surface that extends along a longitudinal axis of the blank between a first end face and a second end face, forming a shear zone in the blank by softening a longitudinal section of the blank and subjecting it to a thermal-mechanical intermixing treatment, and displacing the shear zone along the longitudinal axis of the blank. The displacement of the shear zone along the longitudinal axis of the blank is superimposed by a simultaneous oscillating motion of the shear zone along the longitudinal axis of the blank. The first end of the blank is rotated at a first rotational speed and the second end of the blank is rotated at a second rotational speed. An oscillating motion of the shear zone is generated by periodically varying the first and/or second rotational speed.

In some embodiments, the porous carrier is an open cell foam, a weave of strands or stacked meshes.

Abstract: A method for homogenizing glass includes the method: providing a cylindrical blank composed of the glass having a cylindrical outer surface that extends along a longitudinal axis of the blank between a first end face and a second end face, forming a shear zone in the blank by softening a longitudinal section of the blank and subjecting it to a thermal-mechanical intermixing treatment, and displacing the shear zone along the longitudinal axis of the blank. To enable a radial mixing within the shear zone in addition to the tangential mixing with the lowest possible time and energy input, starting from this method, cylindrical sections of the blank are adjacent to the shear zone on both sides, the first cylindrical section having a first central axis and the second cylindrical section having a second central axis, the first central axis and the second central axis being temporarily non-coaxial with each other.

Abstract: A known method for homogenizing glass includes the following steps: providing a cylindrical blank composed of the glass, having a cylindrical outer surface which extends between a first end face and a second end face, forming a shear zone in the blank by softening a longitudinal section of the blank and subjecting it to a thermal-mechanical intermixing treatment, and moving the shear zone along the longitudinal axis of the blank. To reduce the risk of cracks and fractures during homogenizing, it is proposed that a thermal radiation dissipator is used that at least partially surrounds the shear zone, the lateral dimension of which in the direction of the longitudinal axis of the blank is greater than the shear zone and smaller than the length of the blank, the thermal radiation dissipator being moved synchronously with the shear zone along the longitudinal axis of the blank.

Abstract: An ion source with an insertable target holder for holding a solid dopant material is disclosed. The insertable target holder includes a pocket or cavity into which the solid dopant material is disposed.

Additionally, the target holder can be moved from one or more positions where the pocket is at least partially in the arc chamber to one or more positions where the pocket is entirely outside the arc chamber. In certain embodiments, a sleeve may be used to cover at least a portion of the open top of the pocket.
