TOF - 2024

Beams with NTOF as destination.

Intensity cut-offs: 90 - 1000 e10 ppp.

Integrated Intensity

The following plot shows the integrated intensity sent to the nTOF facility from the start of their physics run. The measured data comes from the accumulated sum of FTN.BCT.477:TOTAL_INTENSITY.The prediction curve considers 1.08x1017 protons on target every day, which is a best-guess based on experience.The limit of protons on the target is calculating considering a flux of 2.2E12 protons/second and an availability of 85%.

Beam horizontal trajectories in TT2

Showing horizontal trajectories in TT2.

Data from UCAP: PS.F16.PROC.BPMALPS

Beam vertical trajectories in TT2

Showing vertical trajectories in TT2.

Data from UCAP: PS.F16.PROC.BPMALPS.

Beam Transmission

Showing transmission as follows:

  • PS Ring transmission: ratio between intensity after injection (PR.DCAFTINJ_1) and in FTN (FTN.BCT.477:TOTAL_INTENSITY).

  • Extraction efficiency: ratio between intensity in the last BCT of the line and intensity before extraction: FTN.BCT.477 / PR.DCBEFEJE_1:INTENSITY

  • Overall transmission: the ratio between intensity in the last BCT of the line and intensity after injection: FTN.BCT.477 / PR.DCAFTINJ_1:INTENSITY.

Data is filtered so only values between 0 and 150 % are shown.

The normalised transmission is shown in the second plot:

  • PS Ring transmission- Normalised: PS Ring transmission / PR.DCAFTINJ_1:INTENSITY.

  • Extraction efficiency - Normalised: Extraction efficiency / PR.DCBEFEJE_1:INTENSITY.

  • Overall transmission - Normalised: Overall transmission / PR.DCAFTINJ_1:INTENSITY. Showing data for nominal and parasitic TOF.
