ELETTRA is the third generation light source based in Trieste, ITALY, since 1992

Present injector: 1.2 GeV Linac, energy ramping to 2 - 2.4 GeV

New injector: 150 MeV Linac pre-injector + 2.5 GeV Booster synchrotron at 3 Hz

Full energy injection at up to 2.5 GeV, rapid refills, top-up injection, reliability, stability

The 1.2 GeV Linac will be used for the Free Electron Laser FERMI@ELETTRA

Booster construction just started: completion by end 2007

Booster Control System Requirements and Guidelines

Requirements the Booster control system will be an extension of the existing ELETTRA machine control system (same network, control room computers and servers)

stable and reliable for top-up continuous injection

diagnosis and fixing capabilities implemented remotely (technical gallery inaccessible during operations)

performance and real-time capabilities (3 Hz operations)

Guidelines deployment of off-the-shelf components, open standards and free open-source software

adoption of existing control system software in the frame of a collaboration with other institutes (Tango)

Following the above guidelines, the development time can be noticeably reduced and the overall cost lowered

The existing control system (early ’90s technology): VME, 68k, OS-9, MIL-1553, Ethernet, Unix, Motif, RPC

After partial upgrades of used technology and systems, a new foundation is necessary

Point

Upgrade of the existing Unix workstations and servers with Linux PCs accomplished by the beginning of 2006

Existing control room programs (based on Motif and RPC) ported to Linux

The new booster applications will run on the same PCs

Most of the machine equipment will be interfaced

to the control system through diskless VME

systems called Equipment Controllers (EC)

VME crate: 16-slot VME64x backplane, two hot-swap

redundant power supplies, local controller with Ethernet

for remote monitoring and reset

CPU board: Motorola MVME5100 with PowerPC G4 at

400 MHz

Software: Linux + Tango control system software

Real-time: RTAI real-time extension for deterministic

response

(20 s max latency jitter)

Equipment Controllers

RTAI Kernel(Interrupt Dispatcher)

Hardware

RTAITask1

RTAITask2

Linux


elettra


I/O: analog and digital signals, RS-232/422/485, GPIB,

etc.

I/O hardware: Industry Pack (IP) modules mounted on

VME carriers

PMC modules and VME boards employed where

performance or special features are required

Special I/O: ex. V/F conversion in the Linac klystron

room to reject electromagnetic interferences. VME board

developed in-house

Transition Modules: provide signal conditioning and

clean cabling of I/O signals

GNU/Linux already used at ELETTRA for two years

reliable and robust

deployed in both Intel PCs and PPC VME systems

common source code base for all platforms

CVS used for source repository and revision managing

Software: GNU/Linux

Linux is a good choice

Keep on this way for the booster control system

CORBA as basic middleware for distributed applications

TANGO control system software framework: joined the international collaboration which is developing it (ESRF, Soleil, ELETTRA and Alba) [WE2.3-6O]

Tango meets all our requirements in terms of capabilities, technologies and performance

mature and well tested: ~30 Tango Devices developed and deployed at ELETTRA

the object model helps software development and maintenance: man power reduced

Software: CORBA and TANGO

Tango Meeting at Elettra

active and fruitful collaboration between partners: the developed software is made available to the Tango community

ELETTRA developments: an alarm system [WE3B-1-7O], database redundancy, Qt integration, a Web based browser of historical data, a Web interface to Tango control system, etc.

Software: GUI and Qt

Qt graphical toolkit (by Trolltech)

C++ and Python Tango APIs

Developed three packages to ease GUI

developments:

Ttk (Tango Toolkit): a non graphical

library that provides some classes to

handle the most common Tango client

read and write actions (device proxy,

event subscription, polling threads,

error logs, etc.)

QTango eases writing graphical

control applications by associating a

Tango device attribute or command with

a viewer or a controller

QtControls custom Qt based widgets

suitable for controls and not yet

supported by existing Qt widgets

QtControls

Software: database, scripts and Web

Database: Tango relies on Mysql for device configuration handling. We will also use it

for the Tango archiving system (HDB) and to store machine settings (Save/Restore

application )

Scripting languages

for machine physics measurements and commissioning of new equipment

Matlab and Python will be provided (both supported by Tango)

Web Applications

E-Giga: data browser of historical data archived by HDB

Canone: generic Web interface to the Tango control system

PHP based Web server acts as a buffered client of the Tango control system

browsing of the operating Tango devices and display of device attributes

composition of custom Web pages with configurable widgets. Pages saved

as cookies

Conclusions

construction and commissioning of the booster in parallel to ELETTRA

operations

completion of the project by the end of 2007

control system structure defined, hardware and software components

chosen

adopted the Tango control system: made the necessary integrations to be

deployed at Elettra

in-house hardware developments almost completed

controls developers can concentrate on the specific equipment application

GOAL: control system available from the beginning of the booster

commissioning

the presented control system infrastructure will also be the basis for the

new projects like FERMI@ELETTRA and the upgrade of the existing ELETTRA

control system
