TOF - 2023

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 1x10¹⁷ 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 Intensity

Nxcals variable: F16.BPM:POS_H.

Beam vertical trajectories in TT2

Showing vertical trajectories in TT2.

Nxcals variable: F16.BPM:POS_V.

Beam Transmission

Showing transmission as follows:

• PS Ring transmission: ratio between intensity before ejection (PR.DCBEFEJE_1) and after injection (PR.DCAFTINJ_1).

• 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 90 and 120 % are shown.
