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.

A lower corner connector for a modular sports goal comprises a first tube having a generally circular inner surface and a second tube extending substantially perpendicularly to the first tube. The first tube has an open end for receiving an upright and a base opposite the open end for resting on a surface. A retainer projects inwardly from the inner surface of the first tube for engaging and retaining the upright and permitting the upright to rock toward and away from the second tube within the first tube to assist in absorbing impact forces.

A sports goal comprises a goal frame, including substantially vertically oriented first and second goal posts each having a top end and a bottom end and a cross-bar interconnecting the first and second goal posts at their respective top ends. The bottom ends of the first and second goal posts define a goal line spanning therebetween. A ground contacting base is connected to the first and second goal posts at respective first and second fixed points adjacent the bottom ends of the first and second goal posts, so as to securely interconnect the first and second goal posts. The ground contacting base extends rearwardly behind the goal line to provide upright stability for the sports goal. The first and second goal posts are tiltably movable between a upright position and an impacted position disposed angularly rearwardly of the upright position. A net is secured to the goal frame and the ground contacting base. There are first and second support arms each having a first end and a second end, with the first and second support arms being mounted at their first ends on the ground contacting base and mounted at their second ends in slidable relation on the first and second goal posts, respectively, for sliding movement between a respective lower position and a respective upper position when the first and second goal posts are forced by impact of an object from their respective upright positions toward their respective impacted position.
