GANMVL 4 Petra Schütt
GANMVL motivationGANMVL motivation
• The most likely scenario of a linear collider is that it will be built by a collaboration of existing laboratories, which will remain involved during the operation of the accelerator.
– Prototypes will be developed in one institution and tested with beam in another laboratory
– Equipment will be built and delivered by one partner and needs to be integrated into the accelerator complex by another partner
– Whole parts of the facility will be provided by a remote partner and need to be commissioned and possibly operated with the experts at their remote home institutions
– In situ trouble shooting and repairs needs to be performed with the support of off-site experts
• Advanced means of communication will be necessary to support efficient collaboration.
• The GANMVL project will design and build a novel collaboration tool and test it in existing accelerator collaborations.

GANMVL 5 Petra Schütt
GANMVL motivationGANMVL motivation
• The Multipurpose Virtual Laboratory is a tool to implement the Global Accelerator Network, a Virtual Organisation (VO) connecting international laboratories doing research in the field of accelerators
• The GANMVL project will provide valuable experience of a new way in designing, building and operating large accelerator complexes, and will address the important psychological and sociological issues of the Global Accelerator Network.
• Remote control of an accelerator facility has the potential of revolutionizing the mode of operation and the degree of exploitation of large experimental physics facilities.

Remote Access to GSI (1)Remote Access to GSI (1)
A lot of effort goes into individual solutions for remote monitoring
There is a need to simplify this access

GANMVL toolGANMVL tool
• The tool will be a mobile communication centre which provides immersive video and audio capture and reproduction of an accelerator control room, a laboratory workplace environment or an accelerator hardware installation.
• The tool should be able to connect to standard measurement equipment (scopes, network analyzers etc.) and to elements of accelerator controls and make these connections available to a remote client.
• The remote user should be enabled to participate in accelerator studies, assembly of accelerator components, trouble shooting of hardware or analysis of on-line data as if he or she would be present on site.

WizardsWizards
• Instruments and control panels can be added by the web interface via a wizard. The wizard together with the help system will guide the Local Station administrator in the
procedure. • Generally there are two modes of integration: http and remote
desktop. – The http is suitable when the instrument or control already has a
web interface available – The remote desktop (VNC) is suitable when the instrument or
control is equipped with legacy software which was not designed for the web.
• The help system which is a critical feature of the GANMVL will provide all the necessary information

Integrating instrumentsIntegrating instruments
• In order to integrate instruments or control panels it will be sufficient to fill a web form specifying– the name of the tool which will be presented in the
station tool menu– the internal URL of the instrument or the internal
address of the instrument (IP address and port)– The local port– An optional password (single sign-on)
• this information will be used by the system to program the tunnel
