Upgrading CEBAF to 12 GeV
The Thomas Jefferson National Accelerator Facility (TJNAF) is proposing to upgrade its {approx}6 GeV cw electron accelerator (CEBAF) to 12 GeV with the purpose of extending its reach in exploring the nature hadronic matter, including the explanation for quark confinement. A plan has been developed that carefully balances cost and risk. TJNAF plans to do the upgrade without change to most of the accelerator components. The core of the upgrade is the addition of ten new 100 MV cryomodules and their supporting rf and cryogenics systems. A new experimental hall, devoted to the quark confinement investigation, will be placed so that the beam transits one of the linacs 6 times (vs 5 times for the other linac). Upgrades to the beam transport system will be required. No new developments in beam diagnostics appear to be required. Beam emittances are degraded by synchrotron radiation but meet the needs of the research program. This paper discusses the issues listed above plus requirements for all systems and developmental opportunities presented by the project.
