[Sneap] VDG ion source BN canals

[Chris Westerfeldt]

Jerry,
	Here is a listing in the SNEAP Oddball Suppliers list that I added  
many, many years ago:
Ellis Ceramtek, Inc.                  Precision Ceramic Machining

215 Annandale Center              Ion Souce Insulators (Quartz,  
Sapphire),

Box 5220 etc.

Clinton, NJ  08809

(201) 735-8400

(201) 735-4FAX (FAX)



I have not checked to see if they are still in business or not.
