• The Mission
• We have been tasked by the Directorate, since
  nearly two years ago, to assemble and operate
  with beam the front-end of the Proton Driver
  linac in Meson Detector Building by the end of

Following Orbachs ILC Timeline Comments

• Re-invigorated interest in the Directors Office
  in Proton Driver synergies with ILC and other
  ideas
• Directors statement that he would seek to build
  6 GeV section of ILC
• Establishment of steering group under Young-Kee
  Kim to generate strategic plan for accelerator
  effort
• Immediate impact on HINS/PD effort
• None on HINS Meson RD mission
• Start (actually revival of) discussions on
  possibility of using 6 GeV section of ILC as the
  high energy end of an 8 GeV Proton Driver
• Dont you simply add on the front 2 GeV?
• Are we expected to fit three times the RF power
  into the ILC physical geometry?

HINS RD Facilities Plan

• To address accelerator physics questions for
  a new concept, low-energy superconducting Linac
• we will construct key components of this Linac
  and integrate them into a demonstration
  accelerator in Meson Detector Building
• Pulsed 2.5 MW, 325 MHz klystron RF power source
• 325 MHz high power RF component test facility for
  studying RF power control devices
• Test stand for 325 MHz RT cavities and a test
  cryostat for 325 MHz SC spoke cavities
• Ion source and RFQ as a 2.5 MeV beam source
• 10 MeV Room Temperature Linac
• Three 325 MHz SC spoke cavity cryomodules
• All accelerator sections to be operated with beam
  up to 60 MeV to verify and quantify performance
• This all adds up to building and operating a
  first-of-its-kind superconducting 60 MeV H- linac
