Surveyed contents of storage flask located at TNF. The lid was lifted off roughly 12" up and a pole monitor was swept over the opening. The fields
of the combined items in the flask were 9.84 mSv/h at 12-24". Extrapolated, the field is approximately 3.7 mSv/h at 1/2 m.

Old #7 coil fitting removed, replaced and re-brazed today by M Good. Insulators ready to go back on to magnet coils to be pressure checked.
Image P1020013.JPG shows #7 coil fitting before removal. Heat shielding in the form of small aluminum sheets were installed to protect the magnet
and electrical wiring. |

Reinstalled ceramic insulators #6 7 8 to Q1 magnet by C Ballard. #6 and 8 went on with no issues. The copper tubing on insulator #7 had to be bent to
match the new position of the re-brazed #7 fitting. This may have been due to the removal of the inner and outer conductors (the two copper plates that
clamp the two coils together) during yesterdays repair which shifted the position of the coil. See photos. |
