Gravity Probe B

Testing Einstein's Universe

WEEKLY HIGHLIGHTS FOR WEEK ENDING 14 JANUARY 2000:

STANFORD HIGHLIGHT
We completed all OPS based Probe C tasks and have moved Probe C into the GP-B class 1000 cleanroom. The most recent probe tasks included finishing necktube thermal measurements, performing leak checks of the caging and spin up lines, and moving the probe from the A frame onto the gurney. A test has been performed on the dewar which shows no measureable change in the dc magnetic field at the gyroscope locations. Based upon this result the lead bag will not require replacement, however AC magnetic field measurements must be performed to confirm this plan. Team members involved in this work include C. Gray, R. Leese, J. Maddocks, J. Mester, D. Murray, and M. Taber.
