T8 - 2024

Cumulative Plot

Showing the intensity delivered each week to T8. Dark grey bar shows amount ejected from PS (measured by PR.BCT), light grey shows amount reaching T8 (measured by T8.XSEC070). Also showing IRRAD target of 2.2e16 protons per week and 2018 everage performance of 1.6E16 protons per week. Edge colour of bars shows whether that week passed facility specs.Weeks shown in blue were used for beam comissioning, so should not be expected to meet nominal facility requirments. Data from week 41 is also displayed, but excluded from cumulative statistics as during this week the XSEC had the wrong calibration factor, so the intensity values are artificially high.

Weekly intensity during 2024

Showing the intensity delivered each week to T8. Dark grey bar shows amount ejected from PS (measured by PR.BCT), light grey shows amount reaching T8 (measured by T8.XSEC070). Also showing IRRAD target of 2.2e16 protons per week and mean weekly intensity. Edge colour of bars shows whether that week passed facility specs. Weeks shown in blue were used for beam comissioning, so should not be expected to meet nominal facility requirments. Data from week 41 is also displayed, but excluded from cumulative statistics as during this week the XSEC had the wrong calibration factor, so the intensity values are artificially high.

Centering of east beam by week

Plot showing the percentage of well centered shots (defined as the beam centroid on the central pixel of the BPM1) each week for the T8 beam

Centering of T8 beam throughout run

Plot showing the centering of the T8 beam throughout the run

Beam Transmission

Showing transmission as follows:

  • PS Ring transmission: ratio between intensity in the PS after ejection of parasitic TOF bunch (PR.DCAFTEJE_1) and intensity of the east bunch measured before east ejection (PR.DCBEFEJE_2).

  • Extraction efficiency: ratio between intensity in thelast BCT of the line and intensity before extraction of East beam: T08.XSEC070 / PR.DCBEFEJE_2:INTENSITY

  • Overall transmission: the ratio between intensity in the last BCT of the line and intensity after injection: T08.XSEC070 / PR.DCAFTEJE1:INTENSITY.

Data is filtered so only values between 90 and 120 % are shown.
