Attempted to remove RH parts between Q1, 2 and monitor vacuum box. Removed Q1 to monitor
box parts, could not remove monitor to Q2 parts, pin drive and indium ring are stuck in place. Indium joint is severed however. Collar was removed. |

|
On 8March2016, under W/P C2016-03-08-2, 4VQ3 was lifted out of BL4V with the vault orbit crane where it was first weighed then lifted onto the
RH flat deck rail dolly. It was then moved into the RH basement where it was surveyed before lifting it up onto the Red wagon cart in the RH loading
bay. It was then pulled to the Meson Hall loading bay by fork lift where and then over the Cycloton vault to the top of the E-Hall roof beams under |

|
On 14March2016, 4VQ1&Q2 were removed from BL4V and lowered into the Vault basement B3 level where they were stored in the south west corner
on their respective wood pallets. The hot ends of both magnets were place against the west wall. 4VQ2 was lifted out first and moved temporarily
downstream where it was separated from its magnet stand. Q2 was then craned into the basement where it was tipped 45o to lay on the flat side |

Re-installed indium vacuum joint for 1VQ4, routing installation. R. Kuramoto sprayed silicone grease on to the threads and bushings on pin drive. Drove
down tapererd pins and stopped 1/16" short of old marker markings. RK. Commented on the drive screw bending under load, reversed drive 1/2 turn
to relieve the stress on the screw. |

On Monday found leaking joint was the ring directly downstream of T2. Vacuum group has been spraying Vacseal (http://www.vacseal.net/Pages/default.aspx)
sealant over the last 3 days attempting to get it in between the flanges and have partial vacuum to draw in the fluid. Seven sprays have been completed
as of March 16th. |

|
Assisted beamlines in replacing 2 insulators on 1A Q15 magnet. #10 and #14 insulators were found to be leaking at the ceramic, where the stainless steel
fitting joins the insulator. They were both replaced. During re-installation of the #10 ceramic, the VCR coil termination broke off the coil end and a
new one with updated design (see TBP0379) had to be soldered back in its place. The original SS fittings are deemed to have problems in their construction |

|
Beamlines has changed out another 2 insulators on Q15 after discovering two additional leaks. Insulators #2 & #4 were replaced. One of them failed
on installation (broken ceramic?) and was replaced by another stocked replacement. Magnet was pressure tested and now enegerized as part of power
testing. Doug P. expects repairs to be complete and to cover up the area by tomorrow. |

|
Correction that all supply side (even numbered insulators) ceramic insulators on Q15 have been replaced with new old stock insulators as of today. Beamlines
finds no power or water issues. Expected to cover up tomorrow moving on to the Q12 and Q13 magnet area next week.

1.) Completed covering up 1A Q15.
2.) RH flask currently contains the 8 insulators removed from Q15. 3.6 mSv/h on contact, 40-60 uSv/h @ .5 m. Double bagged. Bag exterior was swiped
clean, inside was not checked (didn’t want to breach interior bag just to swipe components). |

|
On March 7,2019 the Thermocouple (TC) cable which monitors the temperature of the 1AQ14 B/L vacuum joint was broken when the iron shield block (Triumf Dwg
D-3237 aka M8 Tongue block) was restored on the east of the T2 Monolyth. See attached photos. This TC (Omega #KTSS-116U-144) is attached to the 1AQ14
Indium ring seal (Triumf Ref Dwg TBP0372D) and should be replaced the next time this B/L joint is serviced.

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.

The Beam Position Monitor between 1VB1 and 1VM3 has been installed. The indium joints are leak tight, however the V flanges are leaking slightly. The
leak is small enough to still be able to run beam.
