T9 - 2024

Centering of east beam by week

Plot showing the percentage of well centered shots (defined as the BLM asymmetry within limits for both horizontal and vertical) each week for the T9 beam

Centering of T9 beam throughout run

Plot showing the centering of the T9 beam throughout the run

Beam Intensity

Showing beam intensity after injection (PR.DCAFTINJ_1) and before extraction (PR.DCBEFEJE_2) for beams having EAST_T9 as destination.

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 the last BCT of the line and intensity before extraction of East beam: F62.XSEC022/ PR.DCBEFEJE_2:INTENSITY

• Overall transmission: the ratio between intensity in the last BCT of the line and intensity after injection: F62.XSEC022 / PR.DCAFTEJE1: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: extraction/injection / PR.DCAFTEJE_1:INTENSITY.

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

• Overall transmission - Normalised: Overall transmission / PR.DCAFTEJE_1:INTENSITY.
