River Huang 

   Previous two weeks (Apr 1 - Apr 12)
     - “CASA Beam-Beam” update: Updated the interface between ““CASA Beam-Beam” and “Elegant””: the interface-script 
        file under Linux system was translated by python and the python code was added to “CASA Beam-Beam”. Now 
        “CASA Beam-Beam” can generate “mtr” and “lte” format-file automatically; “CASA Beam-Beam” can automatically
        generate “ele” files of Elegant command, again, the results of “CASA Beam-Beam” can be used for beam-beam 
        interaction in Elegant as well. Optimized the demonstration windows of “CASA Beam-Beam” GUI so that the user
        can review numerical results; added the script commands into “CASA Beam-Beam” to plot/save the figure of “Spin
        Response Function”.
      - Simulating and studying - We are simulating and studying the effect on bunch length due to synchrotron tune via 
        both CASA beam-Beam and BeamBeam3D.
      - Attended “JLEIC collaboration meeting,” reported on "Update on JLEIC Ion Polarization and Spin 
        Transparent Experiment"
      - Reported on “Update on JLEIC Ion Polarization and Spin Transparent Experiment”.
   Next two weeks (Apr 15 - Apr 26)
      - Continue to simulate of the zero-integer spin resonance strength and analyze the results;
      - Study and simulate “Beam-Beam effect”;
      - Prepare the poster for IPAC19.


Diagnostic Development - Kevin Jordan 

   Previous two weeks (Apr 1 - Apr 12)
     - Attended an ARIES sponsored workshop on scintillating screens, cameras & optics.
     - Working on getting power setup for Magnetron Project. This will be done in Lab 1 of the LERF. Within the next
       few weeks the first of two transmitters will arrive and be installed in the LERF.
     - Mounted a BNNT Halo monitor screen for the Isotope beam line run the LERF, also worked to get beam to 0G dump 
       and to the 1G dump. Initially the vacuum system was not ready then we were all ready & the drive laser would 
       not stay locked. There were a num bet of items on HCO that were signed off but not operational. We will try to 
       run to the 1G dump in ~6 weeks when we are back at 2K.
     - Working with Joe & Mike to get the first SLM installed in Arc 7 during the SAD. I also mounted a BNNT flag as 
       a part of this installation. 
     - Attending a meeting at ODU about hope to better work together on common projects with the school of engineering.
     - Finishing up some IBIC program details for this fall’s conference.
     - Spent some time on the IPM gun pulser design for the 300 kV experiment.
   Next two weeks (Apr 15 - Apr 26)
     -


Joe Gubeli 

   Previous two weeks (Apr 1 - Apr 12)
     - Finished and implemented the new optical layout of ARC 7 SLM. We now have a filter wheel in front of the first
       optic as Mike T. asked for the second filter wheel is 90mm upstream of the third filter wheel which is located at
       the field stop. The first wheel will contain the slits. I am waiting on input from Mike T. on the width and 
       offset of the five different slits that will be installed here. The second wheel will contain bandpass filters 
       for short and long visible wavelengths along with a vertical and a horizontal polarizer. The last wheel contains
       neutral density filters. Met with Steve S. and Keith C. at the installation location. Steve said he will approve
       the installation but hasn’t yet updated the Atlis.
     - Spent time working on the Beamenizer after we found the system not working when running to the 0G dump. I created
       a test fixture and after a timing board repair I was able to verify the system now works.
   Next two weeks (Apr 15 - Apr 26)
     - VACATION - 1 week
     - Prepare and install the ARC 7 SLM.
