It appears the telecom room in B87 also has HVAC issues -- one of two units specifically for the room not operating, and so hallway door has been propped open to increase airflow. Could we also aim to at least troubleshoot, with any luck fully address, this issue during the HVAC work scheduled for tomorrow?

Mostly agree with this list with one caveat. It is not recommended to use E01/E02/E03 quadrupoles since are designed they set the extraction by deflecting the beam acting as dipoles. Changing them to adjust beam envelope will alter the extraction and we may end up with beam on the nose of the septa or run out of room with the RF separators.
