No questions, just my personal bio.
Only have 2 years of college completed but have taken many courses on the physics of ion implanters when I worked for Varian, which does not do implanters any more, back to Extrion in Gloucester, Ma. My mentor there was Ray Callahan, a brilliant scientist who at the age of 19 designed and built a 100,000 volt PS about 100 mm cubed to ride on an early NASA satellite. My interest is in astronomy and physics. I also am musician with about 40 acoustic guitar, mandolin, dulcimer and keyboard compositions on a site called Soundcloud, so far 62 tracks, with wife and friends singing songs, some on stage in Jerusalem where we used to live and others recorded in our flat there.
