Thu Feb 15 13:18:30 2024, JG, MBS DAQ: target & ring values
|
We are running an MBS DAQ to record the attached list of slow control values of the ring and the target. In most cases this is achieved by converting
analog monitor voltages to frequencies and recording them with a VME scaler (VULOM4B with scaler-firmware). The complete list of signals is attached including
a channel mapping. |

Thu Feb 15 12:40:52 2024, JM. CB, AR, AB, Run30 - uncooled beam on target 29x
|
Run started 13:40
Target density 4.3e11, Beam injection is ~1e7, Pressure in the ring is ~1e-10 mbar.
Detectors have been moved IN with servo motors only (left arm pot = 36.5 mm, right arm pot =37.7 mm |

Thu Feb 15 10:39:50 2024, JM, JG, ML, AG, CB, Run29 - beam optimisation
|
11:27
Run 29 started. Beam energy is 1.3435 MeV/u with a cooler voltage of 751.3 V.
We observe significantly greater count rate for top right detector (DSSD#1) now that the beam energy has been lowered. ADC over range? Beam target |

|
Run 27 Started to check optimsation of the beam - target overlap.
Beam intensity at injection is roughly 1e7 particles
Target density apporx 4.2e11 atoms/cm2 and stable. |
