    Talking points:

    • MagneToF operation and readout at ISOLTRAP and MIRACLS (Lukas)
    • MagneToF operation and readout in central beamline, GLM, and OL2 (Mia and Line)
    • Proposed readout for RC6 MagneToFs (Miguel)

     

    Minutes:

    • OL2 data acquisition tailored for 10kHz laser pulses
    • A lot of data can be generated when running in high-gain mode with large beams
    • Need expressed for automatic switching between high-gain mode with single-ion counting and low-gain mode with picoscope readout similar to the standard FCs
    • Software seems resource intensive 
    • FW stresses that the limitations of a scaler based DAQ has a lot of downsides, such as baseline walk, pileup, baseline drifts, etc.
    • Requirements for RC6 detectors: longitudinal emittance, efficiency, i.e. linearity, not really for single-ion counting and mass measurements
    • Multiplexer from SY-BI currently under development, has at least 4ns resolution with 4 channels, could be extended up to 8 channels. There is also interest in having a 5th input for a user ToF detector. 
    • Switching between low-and high-gain modes could be done with a simple relay
    • SY-BI hardware will be available to be tested at ISOLDE potentially in August
    • SI-STI and RC6 team will write lists of specification to be compared weather a combined solution to be developed is useful for both teams
    • High-performance FPGA data acquisition card seems unfeasible at this point in time and could be tackled after or during LS3
