sPHENIX MAPS tracker discussion

[Edward O'Brien <eobrien AT bnl.gov>]

    Hi Jo and Ming,
     I am reviewing the ALICE FOCAL TDR and see that their EM section
    of the FOCAL uses MAPS ALPIDE pixels sensors for readout, interleaved
    with W plates. The TDR has a long description of how they will
    deal with what they call "BUSY violations" in the ALPIDE readout from
    high multiplicity events. As far as I can tell this is the identical
    data-hang situation that we are experiencing with the MVTX.
    I have posted the ALICE FOCAL TDR at the top of the Indico page for
    today's MVTX electronics meeting:
    https://indico.bnl.gov/event/22140/

    Perhaps the MVTX electronics experts already know all of this information
    or even contributed to this section of the TDR, but if one looks at
    p. 24-38 you can read a detailed description of how ALICE plans to
    deal with the BUSY-violations in their future FOCAL.
    I find it interesting reading. Thanks.
