Body: 

Both the 2L03 & 4cryomodules and the quad magnet are set to 2B tolerance (0.28 mm), and all flanges on the girder are set to <1 mm. In the attached picture, the flange labeled “MQB2L04_DS” — the upstream flange of the spool piece connected to the pump drop — is more than 4.5 mm BR. Since the typical beampipe tolerance for warm-region girders is <3 mm, this 4.5 mm offset will slightly reduce the clear aperture.
What is not shown are the offsets for the flange labeled “CA2L04_US,” which measures 0.34 mm BR and 0.00 mm vertically.

When we hooked up YBBS04 and YBBS06 this morning, we failed to check to see LCW was turned on. We would like Magnet Measurement to check and verify LCW is turned on before we run current through those magnets.
