C-AD Accelerator R&D Division

Superconducting RF Group

Group Headed By: Sergey Belomestnykh

This web site presents information on the Superconducting Accelerator and RHIC Electron Cooling Group, which is in the Accelerator R&D Division of the Collider-Accelerator Department of Brookhaven National Laboratory. Work is supported mainly by the Division of Nuclear Physics of the US Department of Energy.

Upcoming Events: TBD

Most recent events:

• 56 MHz 2nd External Review, March 8-9, 2011

• External Review of the Energy Recovery Linac, February 17-18, 2010.
  • Report of the Review Committee
• External Review of the 56 MHz Superconducting Storage Cavity for RHIC, BNL January 8-9, 2009
• Internal Informational Review of the 56 MHz Superconducting Storage Cavity for RHIC, BNL January 19, 2011
• LHC Crab Cavity Workshop LHC-CC08
  Brookhaven National Laboratory, Upton NY during February 25-26, 2008
• C-AD Machine Advisory Committee Meeting February 11-13, 2008
• Collaboration Workshop, May 24-26, 2006

The meeting was a specific collaboration meeting, by invitation only, for two critical issues related to the electron cooling of RHIC; non-magnetized electron cooling of high-energy hadron beams and photoinjector design for the needed high-charge, high-brightness beam.

• C-AD Machine Advisory Committee Meeting January 23-24, 2006
• C-AD Machine Advisory Committee Meeting Agenda March 10 - 11, 2004

The Mission of the Superconducting RF Group

This group is charged with the physics, design and construction of RHIC superconducting RF accelerators and eRHIC. This includes the design of SRF hardware as well as the construction and testing. SRF subsystems are the Photo-cathode gun, novel photo-cathodes, the high current super-conducting cavity, SRF Energy Recovery Linac, RHIC SRF storage cavity at 56 MHz, SRF polarized electron guns and LHC crab cavity R&D.

In order to verify out design we will build a smaller Energy Recovery Linac outside the RHIC accelerator. This machine will have a maximum energy of 22 MeV and will support a beam current of 0.5 Amperes.
