The power supply for bending magnets of buster ring BEP has reversible current polarity with maximal current up to 10kA and maximal voltage up to 340V. Current instability is better than 50ppm. System is designed like a combination of eight thyristor rectifier modules and their passive filters joined in parallel to organize twelve ; pulse rectifier. System is equipped with the 10kA thyristor bridge to reverse the current polarity.

Creating new installation and upgrading existing facilities require a great amount of control devices. There was designed a unified device set for new control systems. All devices implemented as embedded controllers for incorporating into controlled equipment like power supplies, RF-station and so on. First applications show a lot of advantages embedded controllers over classical modular devices. Now these devices are widely used in control systems both in BINP and in other scientific institutions. Here are presented the developed device set, described implementation and discussed typical applications.

Electron-positron collider VEPP-2000 is under commissioning at Budker Institute of Nuclear Physics. The paper presents architecture, implementation and functionality of the software of the collider control system. The software according to hardware system consists of interacting subsystems responding on different acceleration facility parts. Control system software is based on several TCP/IP connected PC platforms working under operating system Linux and uses client-server techniques.

In BINP for creation of measuring systems with Hall sensors CAMAC - electronics were used many years. This system had good parameters and successfully used for measurements of magnets produced in BINP as for installations of VEPP-family as for foreign facilities: LHC (CERN), SLS (Switzerland), BESSY (Germany), SAGA (Japan). Hardware deterioration and MS DOS application of previous system demanded to design a new electronics and modern software. The paper describes the new VME-based system and MS Windows application developed for replacement of old system. The system hardware consists of VME crate controller, VME - RS-232 interface, VME - CAN interface and three specialized units: Hall-Sensor analogue Interface (VMEHSI), precision ADC (VMEADC16) and Hall carriage Thermo Stabilizer (HTS), fabricated in Budker INP. Resolution of measuring devices is less than 1uV and stability is better than 10^-5. Software of the Hall-sensor measuring system consists of embedded part, which operates on VME-controller under the mcLinux operational system, and user's high-level software "WinHall", which is a MS Windows application with user-friendly graphical interface. The features of new system and practice results are reported.

VEPP-4M collider has been worked since 80th. Growing expenses for maintenance of obsolete electronics make us to conduct a number of modernization programs. The problem is in keeping of facility in operating state during modernization process. To achieve it we have decided to implement new electronics on modern components but pin-to-pin and bit-to-bit compatible with obsolete prototypes. It allows keeping intact software and replacing old equipment by hidden way. There were described two of these new devices. They are intelligent multichannel DACs for controlled power supplies. VEPP-4M includes approximately 300 power supplies for bending magnets and steering coils controlled by these devices. One device provides 16 channel of DAC with resolution 16 bit and accuracy better than 0,01%. The second device is intended for precise power supplies for bending magnets and provides resolution 20 bits and accuracy up to 0,001%. The paper covers different aspects of design and resolved problems and shows achieved results.
