BPM

Agreed on that func specs are: Beam phase measurement w.r.t. RFQ phase
Then we all agree with Michele's assessment on that
•    there is no need for a full standard BPM DAQ and related cables.
•    a 'simple' front end analogue board (filtering + amp) could be needed
•    the measurement can be done via a scope-based DAQ + scripts to tag and log data

Few options for read out:
•    standard scope with his display and OS --> ethernet control and readout
•    Picoscope-like DAQ (no monitor) --> Ethernet --> remote control and readout
•    OASIS : in place at test stand for source, to be checked if spare channels available

Richard will check if spare channels are available at the test stand.

In general: wanting to sample RFQ freq 352MHZ we need ~1GS/s unless we do downsampling (as in LN4 BPMs) and few 100MS/s should be enough

BCT (3 units)
•    DAQ will be based on standard TRIC card, acquisition via FESA and Expert GUI.
•    Everything can be logged in NXCALS, including traces
•    my offline thought/reminder:  
    o    being fully integrated in FESA one can access via PyJapc, for example inside EM scripts to automatically normalize emittance measurements for intensity if needed)
•    Romain proposes to install legacy head amplifier (already integrated on BCT) + upgraded (Marek's) head amplifier, to be integrated on the girder
    o    Romain will contact Benoit R.
•    ABP Baseline is that OASIS is NOT needed for BCTs

Slit-Grid emittance meter
•    SLIT cooling:
    o    with accurate thermo-mechanical simulations pending (we'll go as far as possible anyway)  we agreed on that baseline == implement slit water cooling
    o    Jean is contacting Benoit R. for integration of cooling components and we will see with CV to ensure-setup proper water flow
•    Slits: will be driven by standard VME stepping motor ( FESA = BStepMotorVME)
•    Grids  == standard LN4  FESA classes (BOSEMCTRL + BEMCPS) , driven by standard VME stepping motors (FESA = BStepMotorVME)
•    ABP baseline == use python scripts to make slit-grid an emittance meter
    o    Giulia to verify resources with Alessandra
    o    Federico to provide support
________________________________________
Spectrometer SEM grid
•    48 channels standard IN-OUT grid (only H plane)
•    will need to ask JFC to deploy OP GUI for this device
•    can be logged on NXCALS
________________________________________
Schedule:
•    be ready with all HW necessary to close vacuum on May 1st 2022
•    be ready with all DAQ for starting dry runs on Oct 1st 2022
________________________________________
Conclusions for today:
•    most urgent is to give MME all necessary input for integration (including Slit cooling, EM grids pre-amp boxes, BCT head amps)
•    provide DICs and racks requests to Edgar + Karl Schirm by Nov 15th
