helium filled up to 70% Note from John: Successful helium fill to 70%. (Siemens had originally wanted to do 60% but Tim K. sucessfully requested 70% fill.) Decision made to let magnet sit over the weekend before ramp up. Replacement of plug connectors in bed also discussed. Conversation about service with Roy Weber, service manager. Andy Wren from MAX has been put in the loop by Roy and is monitoring the situation with the ramp up.
