Magnet Measurement:

We teamed up on the MBO dipole and have removed it from Injector beamline and carefully removed the hall chips.

Matt has some fit checks to do at UITF. If you need 1006 magnet steel for new return legs, just let us know.

If not, we will see it when you drop off @MMF for QA and Magnetic Measurements.

Once the OSP is signed by the stakeholders, it would be helpful to attach one to this ATLis as the link will get buried in the comments section as updates come in. Also, a printed copy at the processing site wouldn't hurt either.
