| TUPHA087 | The Timing Diagram Editing and Verification Method | 615 |
|
||
| Preparation and verification of the timing diagrams for the modern complex facilities with diversified timing systems is a difficult task. A mathematical method for convenient editing and verification of the timing diagrams is presented. This method is based on systems of linear equations and linear inequalities. Every timing diagram has three interconnected representations: a textual equation representation, a matrix representation and a graph (tree) representation. A prototype of software using this method was conceived in Python. This prototype allows conversion of the timing data between all three representations and its visualization. | ||

| TUPHA103 | LIA-20 Experiment Protection System | 660 |
|
||
|
In Budker Institute of Nuclear Physics is being developed linear induction accelerator with beam energy 20MeV (LIA-20) for radiography. Distinctive feature of this accelerator in protection scope is existence both machine, person protection and experiment protection system. Main goal of this additional system is timely experiment inhibit in event of some accelerator faults. This system based on uniform protection controllers in VME form-factor which connected to each other by optical fiber. By special lines protection controller fast receive information about various faults from accelerator parts like power supplies, magnets, vacuum pumps and etc. Moreover each pulse power supply (modulator) fast send its current state through special 8 channel interlock processing board, which is base for modulator controller. This system must processing over 4000 signals for decision in several microseconds for experiment inhibit or permit.

| TUPHA169 | Tango Based Software of Control System of LIA-20 | 813 |
|
||
| The linear induction accelerator LIA-20 for radiography is a pulsed machine designed to provide three consecutive electron bunches. Since every pulse is a distinctive experiment, it is of high importance to provide coherence of the facility state and the experimental data. This paper presents overall software architecture. Challenges and particular approaches to designing of a pulsed machine control system using Tango are discussed. | ||

| THMPL09 | VME Based Digitizers for Waveform Monitoring System of Linear Induction Accelerator (LIA-20) | 1291 |
|
||
| Waveform monitoring system plays a special role in the control system of powerful pulse installations providing the most complete information about the installation functioning and its parameters. The report describes the family of VME modules used in the waveform monitoring system of a linear induction accelerator LIA-20. In order to organize inter-module synchronization the VME-64 bus extension implemented in the VME64-BINP crates is applied in the waveform digitizers. | ||

| THMPL10 | New VME-Based Hardware for Automation in BINP | 1294 |
|
||
| A new VME-based crate and modules are presented in this work. This hardware is primarily intended for LIA-20 control system, but we also plane to use it for the upgrade of the controls of existing complexes such as: VEPP-2000, VEPP-4, VEPP-5 Preinjector. Modules were designed with an ability to be used planned projects such as Super c-tau factory. A crate is 6U VME64x compatible crate with additional synchronization, daisy-chain lines and 6U RIO-modules. Each crate has a built-in status monitoring over CAN-BUS with independent power supply. A family of VME modules is based on the same design sample and include: digitizers, timing modules, CAN-interface module, interlock module. All modules are cost effective and have TANGO device servers developed for them. | ||

| THPHA052 | LIA-20 Control System Project | 1485 |
|
||
| The project of the control system of linear induction accelerator LIA-20 for radiography is presented in this paper. The accelerator is a complex pulsed machine designed to provide a series of three consecutive electron pulses with an energy up to 20 MeV, current 2 kA and lateral beam size less then 1 mm. To allow reliable operation of the whole complex, coordinated functioning of more then 700 devices must be guaranteed in time frames from milliseconds to several nanoseconds. Total number of control channels exceeds 6000. The control system is based on a variety of specially developed VME and CAN modules and crates. Tango program infrastructure is used. The first stage of commissioning will take place in the end of 2017 and will include launching 5 MeV version of the accelerator. | ||
