	China Institute of Atomic Energy’s 250MeV superconducting cyclotron (CYCIAE-250) uses the induction coil method to measure the magnetic field in its airgap. To ensure the precision of magnetic field measurement, area of the induction coil needs to be calibrated. This paper designs a set of coil calibration technique based on flipping coil method. The uniform magnetic field needed for calibration is provided by a permanent magnet with good static performance, its field is measured through high-precision nuclear magnetic resonance(NMR) probe. Then the induction coil will then be installed at the same position of the NMR probe. During the calibration process, induction coil is rotated 180 degrees and magnetic flux through it will be recorded by a high-speed digital integrator. Corresponding equipment is also designed to finish this task. This Paper describes this magnetic field measurement method, corresponding magnetic measurement equipment, calibration process of the induction coil and calibrated area of the coil.

TUPB035	Recent Progress of the Beam Background Experiment in the BEPCII	background, electron, simulation, positron	155
	B. Wang, H.Y. Shi, C.H. Yu IHEP, Beijing, People’s Republic of China
	The Beijing Electron Positron Collider II will upgrade to extend the beam energy and the luminosity by increasing the beam current and slightly compressing the beam size, where the beam energy will be extended from 2.3 GeV to 2.8 GeV and the peak luminosity will be up to 1.1×10³³\rm{cm}^-2\rm{s}^-1 at the optimizing beam energy of 2.35 GeV. The BEPCII upgrade is expected to result in challenging levels of beam related background in the interaction region. An precise simulating and mitigating beam background is necessary to protect the BESIII detector and increase the beam current and peak luminosity. The beam related background at BEPCII is mainly from the Touschek effect and the beam gas effect, this paper presents the recent progress of the beam background simulation and experiment.
