Note from Rick from yesterday. As of 10am today they were still working on it.
--
Worked on the mapper since communications was restored. Before lunch it was stopping after the forward ingetral scan and the NMR was always "locked". After lunch the NMR would not read field, Replaced controller (thanks to Ron and Ken Bagget) seems to indicate some fied locally but not on EDM. Connected the scope- signal out is only 4v ( should be 16?). So, in conclusion, we have multiple issues and seem to have lost a little ground today. Several modular plug-in power supplies were checked today and found to be working properly.
Will jump at it again tomorrow. Maybe Ken can assist. Troubleshooting will be inconclusive during the long shutdown with the magnet string locked out.
It's been a l-o-n-g day.
Rick
