  1. Contents of talkMay 2nd 2006Y. Muraki on behalf of the LHCf • 1. Physics goal • 2. The BRAN detector • 3. The particle distribution inside the BRAN • 4. In case the BRAN will be located at 5th slot (30cm Cu, 3.85cm W, 10cm W)

  2. Our Physics GoalThe exposure time is only a few hours

  3. The BRAN detector Luminosity detector in TAN

  4. “Guts” of the luminosity detector that is inserted into case Detail view of bottom Luminosity detector in its case Copper mounting plate Printed circuit board Ionization chamber BEAM

  5. Cross section detail, parallel to beam copper filler Case wall Case wall copper filler Ceramic printed circuit board copper mounting plate signal comb (in orange) Macor chamber wall Macor chamber wall Ground plane comb (in blue)

  6. Cross section detail, normal to beam Case wall Case wall signal comb (in orange) Macor chamber wall Macor chamber wall Ground plane comb (in blue and red)

  7. Configuration of LHCf-BRAN

  8. Particle distribution in BRAN as a function of beam center

  9. The ratio of particles detected by the 4　partsof the BRAN detector

  10. The threshold of BRAN is set at > 500 particles

  11. Particle distribution of Arm #2

  12. Particle distribution of Arm 2 The threshold of BARN >500 ptls.

  13. Ratio of particles detected by each BRAN sensor

  14. The position resolution of the LHCffor Arm #1

  15. The particle distribution in BRAN for original Cu 30 cm

  16. The particle distribution in BARN for 3.85cm tungsten (W) plate

  17. Particle distribution in BRAN without LHCf (linear scale)

  18. Particle distribution in BRAN without LHCf (log scale)

  19. In the case the BRAN is set at the 5th slot

  20. The particle distribution in BRAN for 10cm thick tungsten block is used

  21. Summary of talks • 1. The LHCf experiment can resolve the highest energy cosmic ray problems. • 2. Present configuration of LHCf-BRAN can measure the beam neutral center by both detectors independently. • 3. However installation of the BRAN at the 5th slot will provide us a better result.

  22. The Arm #1 beam pipe structure

  23. The Arm #2 beam pipe structure

  24. Position identification by the LHCf
