  4. Introduction to AD-Target-Area A. DE MACEDO - LS2 AD-Horn Test-Bench activities - ABTEF

  5. Introduction to AD-Target-Area • AD-Target-Area • Creation of antiprotons and injection in AD • 26 GeV/c beam from PS hits a fixed target • Created antiprotons are collected with a magnetic horn • Injected into AD A. DE MACEDO - LS2 AD-Horn Test-Bench activities - ABTEF

  6. Introduction to AD-Target-Area • AD-Horn power supply • 50 µs pulses • 400 kA • 7 kV Horn Horn sandwich line Junction box Clamp Stripline A. DE MACEDO - LS2 AD-Horn Test-Bench activities - ABTEF

  7. Introduction to AD-Target-Area • AD-Horn system • Shared responsibility • TE-ABT : From power supply to power cables • EN-STI : From Junction-Box to Horn From Junction-Box (female connector) to Horn: EN-STI From power supply to cable male connector (junction box side): TE-ABT A.

  9. ADT-Area refurbishment during LS2 • AD-Target-Area activities during LS2 • Removal of old equipment • Decontamination • Installation of new equipment • New target • New trolleys • New shielding • New horn and its power supply A. DE MACEDO - LS2 AD-Horn Test-Bench activities - ABTEF

  10. Summary • Introduction to AD-Target-Area • AD-Target refurbishment during LS2 • AD-Horn Test-Bench • Test campaign • Planning A. DE MACEDO - LS2 AD-Horn Test-Bench activities - ABTEF

  11. AD-Horn Test-Bench • Why do we need a Test-Bench ? • To validate AD-Horn powering equipment • Recently manufactured equipment (2015-2018) • New designs • Location: b195, inside soundproof cabin in order to execute long term tests w/o disturbing neighbouring users A. DE MACEDO - LS2 AD-Horn Test-Bench activities - ABTEF

  12. AD-Horn Test-Bench • Why do we need a Test-Bench ? • Problems on equipment during operation in the past • Broken horn (80’s / 90’s) • Electric arc in clamps jaws (2014) • Electric arc in junction box (2018) A. DE MACEDO - LS2 AD-Horn Test-Bench activities - ABTEF

  13. AD-Horn Test-Bench • Why do we need a Test-Bench ? • Example of incident: Junction-Box (2018) • Electric arc between plates through insulation • Metallography showed molten material (J. Busom, EN-MME) A. DE MACEDO - LS2 AD-Horn Test-Bench activities - ABTEF

  14. Summary • Introduction to AD-Target-Area • AD-Target refurbishment during LS2 • AD-Horn Test-Bench • Test campaign • Planning A. DE MACEDO - LS2 AD-Horn Test-Bench activities - ABTEF

  15. AD-Horn test campaign • AD-Horn Test-Bench • 2x horn produced for operation + spare • 1x instrumented horn for validation tests • Optic fibre gauges instrumentation (EN-SMM) • Measurements (temp, strain) during a pulse • Comparison with simulations (E. Lopez, EN-STI, AD-THOR-EN-0001 and AD-THOR-EN-0002 ) A. DE MACEDO - LS2 AD-Horn Test-Bench activities - ABTEF

  16. AD-Horn test campaign • AD-Horn cycling • Cycling over 2 months at least • Covers operation until LS3 A. DE MACEDO - LS2 AD-Horn Test-Bench activities - ABTEF

  17. AD-Horn test campaign • AD-Horn Test-Bench • Test new design of clamp jaws • Bigger compression range • Allow higher current • Testing in parallel with instrumented horn A. DE MACEDO - LS2 AD-Horn Test-Bench activities - ABTEF

  18. AD-Horn test campaign • AD-Horn Test-Bench • Test equipment manufactured recently (2015-2018) • 2x junction box • 2x stripline • 3x horn (2+1 instrumented) A. DE MACEDO - LS2 AD-Horn Test-Bench activities - ABTEF

  19. Summary • Introduction to AD-Target-Area • AD-Target refurbishment during LS2 • AD-Horn Test-Bench • Test campaign • Planning A. DE MACEDO - LS2 AD-Horn Test-Bench activities - ABTEF

  20. Planning • Main test phases over 2019 • Test-bench preparation and reliability testing (up to March 2019) • Horn cycling and measurements (April to summer 2019) • Other components testing (end of 2019) • Test-bench not operational in 2020 (TE-ABT activities) • Restart post LS2 depending on TE-ABT availability A.
