2. Recent Activities toward Worldwide Remote Operations of Accelerators N. Yamamoto, KEK ICALEPCS2003,Korea

3. Remote Operation of Accelerator Is it a new idea? –NO Most of large accelerators are controlled by computers and network. If you can access one of these computers from network, you can operate an accelerator from anywhere in the world. “So why we need to discuss it?”

4. Control System Requirements for remote operation are anyway desirable for a control system. Therefore any modern well designed control system should be suitable for remote operations without modification! Steve Hunt at “2nd GAN Workshop” Therefore a control system designed for remote operation should be suitable for any control system without modification!

5. Remote Operation of Accelerator Is it a new idea? –YES Current control system is not designed daily “remote operation” in mind. Security –Authentication –Dynamic Privilege control Hw Design for Remote diagnosis Communication between remote “operators” –Phone –Chat –Video conferencing –E-log –And more ?

6. GAN and World wide Remote Operation GAN:Global Accelerator Network –Proposed by Prof. Albrecht Wagner (DESY) in 2000. –GAN is “a global collaboration to construct, commission and operate a large new accelerator facility, based on the experience of current large detector collaborations. ” –ICFA Task Force was setup for this issue and published report in 2001. –A series of GAN workshop was proposed in the report.

7. (Possible) GAN operation scenario Remote Control LOCAL Control Remote Control

8. Characteristics of GAN: 1. Accelerator parts (e.g. injector, damping ring …) are produced by multiple institutions. 2. These institutions remain responsible for their part through commissioning, running and upgrading it. 3. To allow institutions to fully participate there are control rooms at multiple institutions. 4. Operators, accelerator physicists, hardware experts, and module repair people are not necessarily resident at the accelerator site. 5. Maintenance people who can do intelligent trouble shooting and module swapping are on site. 6. During commissioning more people will be present at the site than during normal running. 7. There is good video conferencing for meetings and to allow a virtual presence in the control room 8. The logbook will be electronic so everyone has access to it.

9. GAN Workshops March, 2002: 1st Workshop @Cornel Aug., 2002: Collaboratory tools@Berkley Sept., 2002:2nd Workshop @Shelter Island –Remote Operation March, 2003, WAO 2003 had one session on “ remote operation ” Oct. 2003, 3rd Workshop will be held at Trieste –Focus on Communication tools –http://www.elettra.trieste.it/cotogan2003

10. Working Group 1 Accelerator Experiments with Remote Participation Working Group 2 Controls, Networking and Accelerator Hardware Issues Working Group 3 Telepresence: Technical, Sociological and Operational Aspects

11. GAN and World wide Remote Operation –GAN is a network of Laboratories/Organizations People Remote operation rooms distributed over the world. –World Wide Remote Control of an accelerator is a key component of GAN but NOT a last one. –GAN discussion was started linear collider project in mind, but not limited to it.

12. GAN, Collaboratory, Virtual Lab., GRID GRID: –Share Computer resources over network Virtual Lab –Network based education system Collaboratory –Communication tools to enhance collaborative work of people over network. –Psychology/Sociology GAN: –Organization consists of multi-national institutes –+ GRID + Collaboratory –+ Remote operation

13. Tools for Remote control Modern controls system is “ GAN-Ready ” –Network based –Distributed –Multiple access Possibly add more functionality –Security Authentication Dynamic Access Control –Remote diagnosis Control system design, tools Hardware design for remote diagnosis

14. Dynamic Access Control Authentication at login time may not enough “Control Room” in charge should have a privilege to control access/operation from remote site/person.

15. Operator’s concern –Standard Training for operators –Language for operation –Culture difference between CR –Trust building among operators in the different groups. –…. –Sociological study might be necessary.

16. Tools for Communication Video conferencing/Communication –Needs High quality Audio-Video –Time delay –Psychology: position of camera, size, … –Back-Channel communication in the meeting. Informal information exchange outside of the meeting. J-PARC/SNS experiences shows the difficulty of tele-communication. –Lack of Suitable tools? –Or Nature of human communication?

17. Video conferencing: Does it Work? 1 to 1 1 to N or N*(1 to 1) N + 1 N to M

18. “Remote Experiment on Accelerator Physics”WG Organized after 2nd GAN workshop Discuss Remote Experiments –Learn from the experience of remote experiments http://www.lns.cornell.edu/public/icfa/RE AP/

19. Other Fields NSF: Published a report on “cyberinfrastructure”, Jan. 2003 –NFS announcement on Oct. 13, 2003 The National Science Foundation (NSF) announces the first steps it is taking to develop a state-of-the-art cyberinfrastructure likely to revolutionize the conduct of science and engineering research and education. These steps leverage the agency's recent investments in the Extensible Teasdale Facility and its six-year investments in the Partnerships for Advanced Computational Infrastructure. A lot of interests and some activities in : –Material Science –Fusion Science –Astronomy –Agriculture

20. Activity in KEK Collaboratory –Material Science –Remote operation of Experimental equipment –Tele communication using video conferencing. PKI/PMI tools –Just started –Prototype for evaluation

21. KEK IMSS: Remote Experiment

22. PKI Key and Secure VLAN PKI Key Tohoku U. Secure VLAN Secure Collaboratory KEK

23. Conclusion Therefore a control system designed for remote operation should be suitable for any control system without modification!
