	XAL is a Java framework for developing accelerator physics applications for the commissioning and operation of the Spallation Neutron Source. It was designed to be extensible and has evolved to support ongoing accelerator operations. In particular, the on-line model and applications have been extended to support the Ring. Core XAL design features eased the extension from Linac to Ring support and in some cases made it transparent. We discuss the recent advances and future directions in XAL and the current efforts to open the project to broader collaboration.

	The XAL application development environment has been installed as a part of the control system for the Japan Proton Accelerator Research Complex (J-PARC) in Tokai, Japan. XAL was initially developed at SNS and has been described at length in previous conference proceedings (e.g., Chu et. al. APAC07, Galambos et. al. PAC05, etc.). We outline the upgrades and enhancements to the XAL online model necessary for accurate simulation of the J-PARC linac. For example, we have added permanent magnet quadrupoles and additional space charge capabilities such as off-centered and rotated beams and bending magnets with space charge. In addition significant architectural refactoring was performed in order to incorporate the current, and past, upgrades into a robust framework capable of supporting future control operations. The architecture and design of XAL is as important as its function, as such, we also focus upon the revised architecture and how it supports a component-based, software engineering approach.

ROPB04	Beam Commissioning Software and Database for J-PARC LINAC	698

	A beam commissioning software system based on a relational database (RDB) has been developed for the J-PARC LINAC. We developed two high-level software frameworks, JCE and XAL. JCE (Java Commissioning Environment) based on a scripting language SAD script has been developed in Java with device control, monitoring, online modelling and data analysis functions. XAL has been developed initially by SNS and developed for J-PARC. A commissioning database system has been developed to configure commonly these two frameworks, for model geometry, EPICS control, and calibration parameters. A server for unit conversion of magnet power supplies has also developed for the commissioning software. Commissioning applications for RF tuning, transverse matching, orbit correction, beam-based calibration, beam monitor controls have been developed using the two framework and successfully applied for beam tuning. We report on the status of development for the commissioning software system.
