CLAS12 User’s Activities
CLAS12 Steering CommitteeAppointed by CLAS Users Coording Committee (Dave Tedeschi, Chair)
• Function: To assist the CCC and Jlab to organize and facilitate the role of the CLAS users in the 12 GeV upgrade.
• Meet periodically to discuss issues which may arise.
• Organize meetings and workshops focused on the CLAS12 equipment andphysics (present workshop)
• etc.

The CLAS Collaborationis a Mosaic
• Most CLAS collaboration members are citizens of nations other than the US, primarily European.
• This is our primary strength.
So, please join us and feel welcome!
It can be a lot of fun!
