The control system of the VEPP-4 facility was designed more than fifteen years ago and based on the home-developed CAMAC-embedded minicomputers Odrenok [1]. Five years ago, all computers were connected via Ethernet network. This step allowed us to force an integration of PCs into the VEPP-4 control system. This paper reviews new tools running on the PCs under Linux. The beam diagnostics tool described in this paper provides the data about position and dimensions of e-/e+ beams from CCD matrix controller via 100-Mbit Ethernet. The next tool provides measuring of beam energy at the VEPP-4M collider using a well-known method of resonance depolarization by the observation of the polarization degree on the effect of internal scattering of particles. Data visualization tools are based on CERN ROOT framework. Hardware and software aspects of the systems are presented in this paper.

The VEPP-4 control system was designed almost 20 years ago as CAMAC-based distributed control system. Today the main peculiarity of the upgraded VEPP-4 control system is the employment of obsolete CAMAC-embedded 24-bit Odrenok computers in the middle
(process) level. The communication software is developed to provide an effective interaction between user (operator) applications on the high level and executive programs in the middle level. The communication software is Linux-based and includes the Application Server and Device Servers. The Application Server provides channel and database access for user applications. The Device Servers provide interaction with the hardware. The backend database server is based on PostgreSQL. This paper describes the structure of the VEPP-4 control system database and data/channel access procedures.
The beam energy measurement system for the VEPP-2000 electron-positron collider is described. The method of Compton backscattering of $CO$ laser photons on the electron beam is used. The relative systematic uncertainty of the beam energy determinatio
n is estimated as 6cdot10^{-5}. It was obtained through comparison of the results of the beam energy measurements using the Compton backscattering and resonance depolarization methods.
Colorado State University (CSU) and Fermi National Accelerator Laboratory (Fermilab) have been developing a control system to regulate the resonant frequency of an RF electron gun. As part of this effort, we present initial test results for a benchma
rk temperature controller that combines a machine learning-based model and a predictive control algorithm. This is part of an on-going effort to develop adaptive, machine learning-based tools specifically to address control challenges found in particle accelerator systems.
The current status of the control system for a new high intensity proton accelerator, the JAERI-KEK Joint Project, is presented. The Phase 1 of the Joint-Project has been approved and recently started its construction at JAERI site at Tokai. The firs
t beam commissioning is scheduled in 2006. In parallel with it, a 60-MeV Linac is now being constructed at KEK site at Tsukuba for R&D purpose. Recently the Project has officially decided to use the Experimental Physics and Industrial Control System (EPICS). Under the EPICS environment, we are challenging to implement the Ethernet/IP network for all communication, even at the level of end-point controllers which are so far connected via a field bus. In order to realize such a system, three new controllers (PLCs, WE7000 stations and general-purpose Ethernet boards) are being developed. A prototype EPICS driver for the PLCs works fine and is used to control the ion-source at the KEK Linac.
We present our experiences in managing the development cycles of the control systems for ANKA and the ALMA Common Software. Our team consists practically only of undergraduate students. Stimulating and rewarding the students with cutting-edge technol
ogies and travel to conferences like this and installation fieldwork are an important positive factor in raising their motivation. However, building any system with a group of inexperienced students is quite a challenging task. Many problems occur with planning deadlines and missing them, organizing and managing development, sources, and documentation and also when dealing with conventional program management rules. To cope with them, we use many tools: CVS for versioning and source archiving, Bugzilla for keeping our bugs in order, a to-do list for managing tasks, an activity log and also many other programs and scripts, some found on the Internet and some made by ourselves. In the end, we had to become organized like a professional company. Documentation and demos can be found on our homepage: http://kgb.ijs.si/KGB. Because of powerful intranet/web front-ends of all those tools, our Internet pages are the central resource for developers, who work mostly off-site.
