    keyword=INJ DAQ tests with oversampling

    The following runs were taken with different versions of the CRL used on the g0inj crate. One of the things tried was to increase the timeout interval; that had minimal effect on the missed reads.

    If you want to take oversampling runs with the VQWK modules, I would suggest using vqwk_nsamp less than 450, and perhaps using the CRL, g0inj_pking_2010may14c.crl. There are still some behaviors that I don't really understand, which occur when the nsamp is closer to the integration period (but still shorter than the integration period). But it probably is okay for smaller values of nsamp.

    At the end of these tests, I reverted to the standard version of the g0inj CRL file, which was last compiled on Oct 21 2009.

    SUMMARY OF TEST RUN CONDITIONS:

    PREX Run 3856: Standard g0inj.crl
    RD=160, IT=2920, OS=0, vqwk_nsamp=925

    PREX Run 3857: Using g0inj_pking_2010may14a.crl
    RD=160, IT=2920, OS=0, vqwk_nsamp=925

    PREX Run 3858: Using g0inj_pking_2010may14a.crl
    RD=0, IT=200, OS=5, vqwk_nsamp=10
    There are lots of error messages in all of the ROCs...

    PREX Run 3859: Using g0inj_pking_2010may14a.crl
    RD=160, IT=1430, OS=1, vqwk_nsamp=10
    This should have had vqwk_nsamp=450

    PREX Run 3860: Using g0inj_pking_2010may14a.crl
    RD=160, IT=1430, OS=1, vqwk_nsamp=450

    PREX Run 3861: Using g0inj_pking_2010may14b.crl
    RD=160, IT=1430, OS=1, vqwk_nsamp=450

    PREX Run 3862: Using g0inj_pking_2010may12a.crl
    RD=160, IT=1430, OS=1, vqwk_nsamp=450

    PREX Run 3863: Using g0inj_pking_2010may14c.crl
    RD=160, IT=1430, OS=1, vqwk_nsamp=450

    PREX Run 3864: Using g0inj_pking_2010may14c.crl
    RD=160, IT=1430, OS=1, vqwk_nsamp=200

    PREX Run 3865: Reverted to standard g0inj.crl
    RD=160, IT=2920, OS=0, vqwk_nsamp=925
