72nd ICFA Meeting

Valencia, Spain
6 July 2014

  1. ILC Progress in Japan
  2. An ILC preparatory office has been established in KEK, and there is a proposed ILC budget in Japan for the next 5 years totaling US$250M. A MEXT task force was set up in February 2014, with an Academic Experts Committee under it; this Committee has under it a Particle/Nuclear Physics Working Group and a TDR Validation Working Group. A full proposal is anticipated in 2017, with a construction start in 2018;

  3. Global Planning for HEP, including a 100 TeV Collider
  4. Over the next few years, Europe will look at a ~ 100 TeV pp collider, with an 80 – 100 km circumference; it could also be used for heavy ions and possibly electron-hadron collisions. There is a possibility of 350 GeV e+e- collisions in the tunnel, but pp is the primary goal. A study will be made on the physics of such a pp machine compared to a high energy (~ 33 TeV) LHC option; high-field magnets are needed for both machines. It is hoped to have a TDR and an “educated” cost estimate in 5 years.

    Planning for future particle physics facilities in China started in 2012. China does not have the capability to build a large proton machine now, but could consider an e+e- machine (CEPC) (~ 240 GeV) in a large tunnel; the tunnel could later contain a pp collider. Construction could start after 2020. The e+e- machine is complementary to the ILC, and China still supports the ILC. China feels that it needs a particle physics project at home in addition to taking part in international projects.

  5. ICFA Statement
  6. ICFA issued a Statement intended to eliminate confusion as to its support of the ILC, and to also encourage studies of future machines.

  7. 2014 ICFA Seminar
  8. The planning for the next ICFA Seminar was described; it will be held at IHEP, Beijing, on 27-30 October 2014.

  9. Linear Collider School

The Linear Collider School has been very successful, but there are now funding issues, and there is no linkage to other accelerator schools. A working group has been formed to discuss the future of the School; the School in October/November 2015 will be hosted at TRIUMF; the School in 2016 will be in Japan, arranged by KEK; and the School in 2017 will be a specialized CERN School. For funding, the suggestion is to move from lab/funding agency support (which has become increasingly difficult to obtain) to a fee-based model, similar to other accelerator schools.
