Joe Gubeli
Previous two weeks (Aug 17 - Aug 28)
- Isotopes –Attended several planning meetings. Setup some equipment needed for next week’s run
- ARDDOT - Had a few meeting with the Injector group to determine if the new viewer image design would work for them. They have some
very tight spaces. Met with the I&C group to show them the viewer imager and to test a lipstick replacement camera. The tested camera
has an nonadjustable lens an images a lot of the tube with a small image of the view screen. Not sure that it is a good replacement. The
I&C folks had to run to another call and didn’t have time to assemble an imager. We will reschedule for another time. Have inventoried
and conveniently placed all the parts received for the imager. Still have a few parts including the cameras that have not arrived.
Next two weeks (Aug 31 - Sept 11)
