Both the MAG-R and VMAG-R processes have been completed with success in our lab; and we are currently conducting tests to determine which materials are best and which VIs are best suited to these processes. Some positive things have come from this research. First, we can remove the pinch tube from the older pinch tube designs and install a new getter material. Additionally, the same opening can be resealed with modern brazing filler material far better-suited to this application than the original pinch tube that long has been a problematic seal off and point of failure in many VIs. Second, we can now add more and better getter material as the economic model has changed substantially from when they were originally manufactured. These processes have been patented in the U.S. and abroad and research is underway to improve and bring these, or at least one of these, processes into production this year.
