SECTOR TEST PREPARATIONW. Bartmann, C. Bracco, J. Uythoven

LIBD Meeting, 10-Feb-2015

Sector test measurements I• SPS extraction

• MKE waveform scan• Rough aperture check if not yet done

• Establish downstream TL trajectory • Screens matching• Check BPM/corrector polarities (and optics) with kick response• Measure TL dispersion• Trajectory stability• TL aperture – redo TI 2 hor

• Threading through injection region onto closed TDI• Rough setup of TCDI, TDI, TCLI• Aperture in injection region• Orthogonal steering• MKI waveform scan (change of screen conductors, TMR aging)• MKI synchronisation• AGK synchronisation• IQC injection oscillation interlock

Sector test measurements II• Beam dump• Synchronisation• Rough check of extraction channel aperture• BTVD/BTVDD image• Test 14/15 MKD knob• MKB waveform – check with ~5 pilots• MKD waveform – never tested, procedure to be set up

Preparation• Knobs

• for TI 2 horizontal aperture measurement – Francesco• For vertical MSI aperture measurement – Francesco• For TCDI and MKI validation – Francesco• For MKD test - Matthew

• Beam positions • on injection region screens for MKI on/off – Francesco• on dump region screens – Matthew

• List of settings for• MKI max/nom voltage, MSI current - Francesco• MKD max/nom (6.5 TeV), MSE current - Matthew

• MKB/MKD waveform procedure – Matthew• Correctors for orthogonal steering in injection region - Francesco• Check rights for MKI waveform test – Wolfgang, Mike• Settings for TCDI, TDI, TCLI, TCDQ – Chiara, Wolfgang
