TOF - 2025

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 Weekly Flux and Daily Rate

Showing flux per week and proton rate per day.

Weekly flux: The average flux over time range corresponds to the average of all data per week, while the average flux excluding low periods corresponds to the average of the hourly averages for which the value is at least 10.

Daily rate: The daily proton rate sent t Nxcals variables: FTN.BCT477:Acquisition:totalIntensitySingle.

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 90 and 120 % are shown.
