	The typical problems occurring during commissioning of the first turns in the storage rings include shorted coils or reversed polarity of the magnets, cross-cabling of magnets power supplies and reversed polarity of BPMs. In this paper we describe a dedicated high level control application, which was created and utilized for commissioning of the first turns in NSLS-II storage ring.

	The NSLS-II storage ring is protected from possible damage from insertion devices (IDs) synchrotron radiation by a dedicated active interlock system (AIS). It monitors electron beam position and angle and triggers beam drop if beam orbit exceeds the boundaries of pre-calculated active interlock envelope. In this paper we describe functional details of the AIS and discuss our experience with commissioning of the AIS for the first six IDs installed in the storage ring.

MOPWI023	Development Plan for Physics Application Software for FRIB Driver Linac	1201
	M. Ikegami, G. Shen FRIB, East Lansing, Michigan, USA
	Funding: Work supported by the U.S. Department of Energy Office of Science under Cooperative Agreement DE-SC0000661. FRIB is a heavy ion linac facility presently under construction at Michigan State University, USA, and its driver linac accelerates CW beams of all stable ions up to uranium to the energy of 200 MeV/u with the beam power of 400 kW. We plan to start beam commissioning of the driver linac from December 2017. An adequate software environment and infrastructure is critical for our commissioning and operation. Recently, a middle layer based architecture, EPICS V4 based services for example, for physics application has been rapidly developed at other facilities like NSLS II. It has been showing its flexibility, and portability. After reviewing those recent developments, we decided to adopt these services as software infrastructure for FRIB driver linac commissioning. It enables us to take advantage of their cutting edge technologies and maturity as a system sustained by the experience accumulated in the commissioning of NSLS-II. In this paper, we present a plan to develop physics application software for FRIB driver linac based on EPICS V4 services and related software. We also present a plan to adjust these EPICS V4 related software to meet the FRIB specific requirements.
