  The cryomodule I for ADS Injection-I had been designed, fabricated and online
tested. The CM1 contains seven superconducting magnets, seven superconducting
spoke cavities and seven beam position monitors. The superconducting magnet,
which is a kind of multifunction magnet in a 170mm length axial space, contains
a solenoid for beam focusing and two correctors for orbit correction. The
design goals for the magnets are to meet the required integral field strength
and to reduce the leakage field of less than 2 G at the nearby superconducting
spoke cavities. The 2.1K, 31 mbar cryogenic system, where the magnets and spoke
cavities shared with, force the magnet must select a kind of conduction cooled
current leads. The first one of the batch magnets was tested in a vertical
Dewar in HIT in July, 2014. The measurement results met the design
requirements. Online operation of CM1 in September, 2015 showed that seven
magnets can work at 230A under 4.2K and 2.1K respectively. This paper will
present the magnet and current lead design, field measurement and the
installation progress.
