	Funding: The National Natural Science Foundation of China(11105166)； Youth Innovation Promotion Association（2015011） A 324MHz Alvarez-type Drift Tube Linac (DTL) is used to accelerate the H⁻ ion beam from 3 to 80 MeV with peak current 15mA for China Spallation Neutron Source (CSNS). DTL is composed by 36 meters cavity and 161 DTs, the DT magnet coil adopted SAKAE structure with compact, smaller aperture. Magnetic field is measured by self-developed high precision rotating coil measurement system. This paper introduces the rotating coil measure-ment system simply and presents the 161 DTs magnetic field measurement results comprehensively, include mag-netic field center offset, integral magnetic field, higher-order harmonics. In addition, cooling test result of magnet coil is also presented.

	This article is devoted to the experimental study of tun-ing method for an Alvarez-type drift tube linac (DTL) of the Compact Pulse Hadron Source (CPHS) project at Tsinghua University. The biperiodic structure based on the post couplers are introduced to overcome the instability of the Alvarez DTL tank which is used to operate in 0 (or 2π) mode. The experimental method and results are pre-sented, and the tuning scheme for the formal CPHS DTL is summarized from the tuning experiment.
