  1. Optimum proton beam energy considerations R. Tschirhart Fermilab November 10th , 2009

  2. Sensitivity of Kaon Physics Today • CERN NA62: 100 x 10-12 measurement sensitivity of K+ge+n • Fermilab KTeV: 20 x 10-12 measurement sensitivity of KLgmmee • Fermilab KTeV: 20 x 10-12 search sensitivity for KLgpme, ppme • BNL E949: 20 x 10-12 measurement sensitivity of K+gp+nn • BNL E871: 2 x 10-12 measurement sensitivity of KLge+e- • BNL E871: 1 x 10-12 search sensitivity for KLgme Probing new physics above a 10 TeV scale with 20-50 kW of protons. Next goal: 1000-event pnnexperiments...10-14 sensitivty. November 10th 2009. R. Tschirhart - Fermilab

  3. Proton Sources Considered • High energy proton synchrotrons: Fermilab Tevatron, CERN SPS. • BNL AGS and JPARC MR machine. • The IC1 8 GeV proton source concept. • The IC2 2.x GeV proton source concept. November 10th 2009. R. Tschirhart - Fermilab

  4. Definitions matter… November 10th 2009. R. Tschirhart - Fermilab

  5. IC2 is high power, but what about kaon yields?? Mokhov & Gudima November 10th 2009. R. Tschirhart - Fermilab

  6. IC2 Kaon Yields at Constant Beam Power for Stopping K+ and TOF-based KL experiments GeV ICD-2 Report November 10th 2009. R. Tschirhart - Fermilab

  7. KOPIO and ICD-2 kaon momentum spectra comparison KOPIO Proposal November 10th 2009. R. Tschirhart - Fermilab

  8. ICD-2 Sensitivity to KLgp0nn ICD-2 Report November 10th 2009. R. Tschirhart - Fermilab

  9. IC-2 Sensitivity to K+gp+nn ICD-2 Report November 10th 2009. R. Tschirhart - Fermilab

  10. Optimum Energy for stopped and slow kaon experiments… • 4-8 GeV. 1000 event plausibility begins around 2.6 GeV. • For pure K0 experiments: 2.6-3.0 GeV • What’s the cost? IC2 is a $1B class facility (DOE TPC accounting) Raising the IC2 beam energy by 500 MeV increases the TPC by about 8%. Recommend 2.6 GeV with upgrade option to 2.9 GeV. November 10th 2009. R. Tschirhart - Fermilab
