TOF - 2021

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. Two calculated intensity predictions are shown in the plot. One is based on the different super-cycle configurations used throughout the year. It considers an availability of 85% and 800x10¹⁰ p and 350x10¹⁰ p for dedicated and parasitic bunches, respectively. The second prediction considers 1x10¹⁷ protons on target every day, which is a best-guess based on experience.

Beam Intensity

Showing intensity after injection and before extraction.

Nxcals variables: PR.DCAFTINJ_1:INTENSITY, PR.DCBEFEJE_2:INTENSITY.

Beam horizontal trajectories in TT2

Showing horizontal trajectories in TT2.

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.
