CLAS12 Steering Committee

• Appointed 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 and
• physics (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!
