EIC Advisory Committee
• Established at the beginning of 2009 at the initiative of the BNL and JLab
laboratory directors to:
• “periodically review EIC progress and to provide feedback and advice on
the project development”

Immediate & Most Important Task
“Produce a complete conceptual
design of a medium-energy
polarized EIC based on CEBAF”
To be presented at next EICAC Meeting April 10 or 16, 2011
Scope of Intermediate Design Report
Report ~50 pages by April 1, 2011
• Conceptual design of all major components of the ion complex
Schematic layouts, descriptions, identified technologies,
existing systems as models
• A set of parameter tables
Complete, self-consistent, preferably within state-of-the-art
• A set of critical R&D issues
For the presentation
• A good scenario
Be able to walk people through the whole complex
Be able to bring beam from source to IP, step-by-step
Design Goals for MEIC Ion Complex
• Develop a concept for a technically sound and cost effective ion
complex for the MEIC project
• The MEIC ion complex should be able to provide the colliding ion beam
required for successful operation of a medium energy EIC
– Polarized light ions (>75% in the collider) and un-polarized heavy ions
– Colliding beam current up to 1 A (~5x109 protons/bunch)
– Compatible with a bunch repetition frequency of 750 MHz
• Capable of being upgraded to 1.5 GHz
– RMS bunch length of 5 to 10 mm for colliding beams
– Emittance at injection of <5 mm-mrad
– Round beams at injection
– Compatible with a luminosity lifetime of ~10 hours
Ion Complex Design Workshop Goals
• Review the current status of MEIC ion complex design
• Identify any missing parts of the design
• Identify any design inconsistencies
• Identify key R&D required for this stage of conceptual design
• Make a plan for future design work and R&D studies
• Assemble an R&D team and establish new collaborations
• Plan for the Intermediate Design Report
– Ready by April 1, 2011
