First tries

• In February 2007, when Mark and Janice were on remote shifts during BBA runs– Were using AOL messenger (voice & text chat)– VPN to nanosun.kek.jp for data analysis and transfer

• After this positive experience were starting to discuss regular remote participation

Remote Participation

• Principle – Participation to be focused on the work (e.g. data

analysis) which does not involve remote control, to respect the ATF safety rules

• Desired capabilities– possibility to see the monitors of ATF control room– have audio & video connection with ATF control room– have access to a computer where data analysis can be

done, but not the control• Earlier thoughts on realization:

– Use Webex with desktop sharing to transmit ATF monitors+ phone with callback for voice

– Use VPN to nanosun.kek.jp for data analysis

Testing Webex for remote participation for May run. (ATF online in SLAC office)

Remote participation Works!

• Seeing ATF control room monitors in real time, • seeing and hearing people at ATF control room, • being able to discuss the plan of measurements, • look at fresh data and correct the plan on-the-fly, • even hearing “beam-on/off” in Japanese …

• … all this makes terrific feeling of presence and participation

May 16, 07 Global Design Effort 13

Where improvements are needed

• Audio, audio, audio …

• Could not use Webex call back as planned originally– expandability and quality of normal phone is hard to

beat now

• End up using Skype, which has limitations– audio quality is not perfect; – expandability is limited: three party conference call

cannot have video

May 16, 07 Global Design Effort 14

To consider for future RP runs

• Study if can get dedicated phone line to ATF control room

• Get proper conference phones with satellite microphones (normal or Skype compatible) – cover the whole room, so e.g. the shift change

meeting could be also heard remotely

• If Skype use will be continued, get dedicated computer, proper cameras with large screens, etc.

…To consider for future RP runs

• It is not only hardware which matters…

• Planning, organization, patience are very important

• With proper planning, RP may be very useful
