ISTC collaboration

• International Organisation, Nonproliferation
  Program
• Coordinates the efforts of numerous Governments,
  International Organizations, and Private Sector
  Industries, providing Weapons Scientists from
  former SU States new Opportunities in intern.
  Partnerships. (Provides Funding for these
  Collaborations)
• Three Linac4 Projects, which include the
  Construction and Machining of complete
  Prototypes, were approved this year by the ISTC
  (1.5 M, Proposals submitted in 2002/2003), one
  with IHEP

ISOLDE wants to submit 2 Proposals in
Collaboration with IHEP Protvino 1. Construction
of the IH Cavities for the Upgrade to 5.5
MeV/u 2. Design and Construction of additional
Cavities up to 10 MeV/u and of the required
rf-Amplifiers - Discussions have started with
IHEP Staff

REX beyond 5.5 MeV/u
Proposed by IHEP An RFQ DTL Section driven at
H-mode of RF Oscillations. Transverse Focusing
period 2bl, Pattern FFDD. Effective acc. Voltage
around 4 MV/m. Aperture Hole Diameter 10 mm.
Normalized transverse Acceptance 34p mm mrad. ?
5.5 10 MeV/u Two 3.5 m Tanks, rf-Power 500
kW/Tank

Outlook
- Hall Extension in January 2005, available in
April/May - Shutdown 2005/2006 Installation of
two S-shaped Target Beam Lines in the new Hall
(still 3 MeV/u beam) ? better beam quality,
better X-Ray protection of of MINIBALL etc.
etc. If ISTC Collaboration works out.. -
Production of IH Cavities, Setup of 300 kW
Amplifier in the extended Hall until Shutdown
2007/2008 - Shutdown 2007/2008 Installation of
5.5 MeV/u Linac, in parallel Modification of
BERTRONIX Amplifiers - 2008 2010 Construction
of the 10 MeV/u Linac in Russia
