[Sneap] Decommissioning GS

[Kessel, Quentin]

Good people:

     It is time to decommission my ancient HVEC GS accelerator.  Before I learn the ins and outs of our new State laws on giving things away that have property tags, I would like to know if there is any interest in this accelerator or any of its parts.  I'm expecting to trash it, perhaps getting some travel money from selling the tank to a metal recycler!

     This machine has an unusual history.  It started life as an 2 ma electron irradiator (1 ma upcharge and 1 ma downcharge), and was later converted to positive ion useage by HVEC's subsidary, Ion Physics Corporation, for ion implantation.  I installed it at the University of Connecticut in 1977.  It is an unusual machine with a wide belt (a new D-BL 207-126 belt is in storage) and a tank extender, in order to rate it at 2MV (which I never reached! Ran it at 1.6MV a good deal of the time).  It has two positive ion tubes that need reconditioning (won't run above 1 MeV these days).  With some ion species, the tubes have run with nearly half a milliamp of total output, and routinely ran at 200 microamps total output when required.  It presently has a Bethge-Baumann discharge source for higher charge state ions (which I may want to keep).  There are remnants of an rf source around and the hot filament in a graphite bucket source used by Ion Physics Corp. is still intact.

     I'm retired and am finishing up my last graduate student, and the lab space must be cleaned up for a new faculty member during the spring semester.

     Regards to all! Quentin Kessel
