      - MADX optimization of integrated solenoid/quadrupole/skew quadrupole fields for a compact spin rotator. Integrating the quadrupole and skew quadrupole fields into the
 +
        solenoids can potentially save ~10 m of space per solenoid, for ~20 m total. Solutions matching to the optics while zeroing out the coupling parameters beta12, alfa12,
 +
        beta21, and alfa21 using PTC_TWISS in MADX were very difficult to find when dispersion constraints were also included in the optimization. Preliminary solutions for both
 +
        solenoid modules were found by relaxing the horizontal dispersion and dispersion prime constraints on the match. The coupling parameters are about an order of magnitude
 +
        larger than in the original lattice, and further work is needed to study the implications of this on the beam dynamics in the spin rotator.
 +

        the same day (actually after hours in the evening) and irradiated the gallium for a total of 26 hours.  The LERF was not being cooperative and we lost 12 hours to an RF

     - Completed August 2020 EIC Design Update Newsletter.
     - MADX optimization of integrated solenoid/quadrupole/skew quadrupole fields for a compact spin rotator. Working on solutions that match to the existing optics for both
       solenoids.
     - Attended various meetings on second IR-related topics.
     - Attended closeout session of DOE OPA status review of EIC.
   Next two weeks (Sept 14 - Sept 25)
     - Submitted input to EIC Biweekly report.
     - MADX optimization of integrated solenoid/quadrupole/skew quadrupole fields for a compact spin rotator. Integrating the quadrupole and skew quadrupole fields into the
       solenoids can potentially save ~10 m of space per solenoid, for ~20 m total. Solutions matching to the optics while zeroing out the coupling parameters beta12, alfa12,
       beta21, and alfa21 using PTC_TWISS in MADX were very difficult to find when dispersion constraints were also included in the optimization. Preliminary solutions for both
       solenoid modules were found by relaxing the horizontal dispersion and dispersion prime constraints on the match. The coupling parameters are about an order of magnitude
       larger than in the original lattice, and further work is needed to study the implications of this on the beam dynamics in the spin rotator.
     - Attended meetings on revisions of the IMP experiment paper.

     - Isotopes –Attended several planning meetings. Setup some equipment needed for next week’s run
     - ARDDOT - Had a few meeting with the Injector group to determine if the new viewer image design would work for them. They have some
       very tight spaces. Met with the I&C group to show them the viewer imager and to test a lipstick replacement camera. The tested camera 
       has an nonadjustable lens an images a lot of the tube with a small image of the view screen. Not sure that it is a good replacement. The
       I&C folks had to run to another call and didn’t have time to assemble an imager. We will reschedule for another time. Have inventoried
       and conveniently placed all the parts received for the imager. Still have a few parts including the cameras that have not arrived.
   Next two weeks (Sept 14 - Sept 25)
     - Isotopes – Help as much as possible with the upcoming experimental run.
