| THCEMH01 | TANGO Activities in BINP | 116 |
|
||
| Several years of experience using TANGO Control system are discussed in this paper. Construction of Linear Induction Accelerator (LIA-20) was the driving force for introduction of TANGO in Budker Institute. In the frame of this project, significant number of TANGO Classes for different types of hardware were developed and basic program infrastructure was provided. This progress made it feasible to apply TANGO to other facilities. Therefore, it was used in some subsystems at VEPP-2000 and vacuum stand. This paper presents overview of construction of TANGO based control system. The problems, which arise during its introduction to existing control system, are discussed as well. | ||

| THCEMH02 | Modern Digital Synchronization Systems for Large Particle Accelerators | 119 |
|
||
| The review of modern approach to synchronizing large physical installations including accelerators is given in this paper. This approach is based on using digital modules connected by an optical link to transfer a mixed clock/data signal. A sub-nanosecond jitter and nanosecond resolution can be achieved this way as well as dynamic delay compensation and precision timing. Several modern synchronization systems based on this principle are discussed: White Rabbit, MRF, J-PARC and BINP developments. | ||

| WEPSB45 | Upgrade of Quench Recording System for Multipole Superconducting Wigglers at BINP | 369 |
|
||
| Magnetic poles of superconducting wigglers (SCWs) are passed through "training" phase during fabrication of SCWs at Budker INP. In "training" procedure magnetic field is increased until superconducting coils enter the resistive state. Quench Recording System (QRS) is used for registration of waveforms in each coils to determine fault initiator coil. The total number monitored coils reach 312. Outdated QRS is based on modules in CAMAC standard and requires modernization. The basis of the new system is VME64-BINP crate with multichannel digitizer ADCx32 and RIO-module for safe signal receiving in high-voltage common-mode environment. The structure and details of the new system, as well as the experience of using the old one are given in the report. | ||

| THPSC10 | Development of Modern Digital Synchronization Modules at BINP | 426 |
|
||
| Modern digital synchronization system for big physical facilities is developed at BINP. It allows synchronizing the spatially distributed control devices with an accuracy of ±2 ns and low jitter (< 100 ps). Accurate time distribution and delay compensation is provided, as well as an ability to react to external events with a determined latency. Two modules are used in this subsystem: S-Timer and L-Timer. S-Timer provides a synchronized 250 MHz clock signal with embedded events data through the optical link to nine L-Timers or S-Timers. L-Timer decodes the signal from the optical link and provides synchronization pulses to final control devices. | ||

The Distributed Monitoring System for Local Controllers of Linear Induction Accelerator | |
|
||
| The control system of a Linear Induction Accelerator (LIA-20) consists of 40 local controllers, distributed along the total length of about 100 meters. These controllers are based on VME-BINP crates. The system should provide high reliability of operation in conditions of strong electromagnetic noise and radiation. The developed monitoring system that allows registering value and deviations on the VME supply rails, measures temperature and other peripheral parameters is discussed in this paper. Monitoring devices are connected by a CAN bus equipped with independent backup power supply. The central program performs periodic polling of the monitored devices to obtain the actual measured values, store it in a database and notify the operator in case of faults. | ||
