  In the commissioning phase of accelerators, many application programs are built and modified frequently by nonexpert programmers. Scripting language such as Python is suitable for such quick development. Since EPICS Channel Access interface library in Python was developed in KEKB accelerator control system, many programs has been written in Python. We have been developing, providing some tools and libraries for Python programming. Some of the recent developments in KEK are reported, and possible applications are also discussed.

  The KEKB asymmetric electron-positron collider complex consists of 8-GeV Linac, high-energy and low-energy rings. Some of the resources were inherited from the previous TRISTAN project, and also they are shared with Photon Factory and PF-AR light sources. In order to realize the long lifespan of the system de-facto and international standard technologies were employed since the early stage, which have been efficiently operated. Several gateway methods were implemented to integrate heterogeneous sub-systems, which are gradually converted into EPICS. Scripting languages are employed for higher-level applications. The ever-evolving control system has enabled flexible and reliable beam operations at KEKB throughout the long period.

  J-PARC accelerator complex consists of a proton linac (LINAC), > a Rapid Cycle Synchrotron (RCS), and a Main Ring synchrotron (MR). The commissioning of LINAC already started in November 2006, while the commissioning of Main Ring synchrotron (MR) is scheduled in May 2008. Most of the machine components of MR have been installed in the tunnel. Introduction of electronic modules and wiring will be made by the end of 2007. For the control of MR, the J-PARC accelerator control network was extended to include the MR related parts in March 2007. IOC computers (VME-bus computers) for MR will be introduced in 2007. In addition, more server computers for application development will be also introduced in 2007. This paper reports the status of development for the J-PARC MR control system.

  An accelerator console system, based on a commercial thin client, has been developed for J-PARC accelerator operation and software development. Using thin client terminals, we expect a higher reliability and longer life-cycle due to more robust hardware (i.e., diskless and fanless configuration) than standard PCs. All of the console terminals share a common development/operation environment. We introduced LDAP (Lightweight Directory Access Protocol) for user authentication and NFS (Network File System) to provide users with standard tools and environment (EPICS tools, Java SDK, and so on) with standard directory structures. We have used the console system for beam commissioning and software development in the J-PARC. This paper describes early experiences with them.
