 Previous two weeks (May 27 - June 7)
     - Conversion of ion linac lattice from TRACK to PyORBIT. The superconducting section of the proton
       linac (5 MeV to 155 MeV) has been implemented using matrix RF gap models, but with older versions 
       of the linac accelerator modules in the PyORBIT code.
     - Conversion of TRACK proton linac lattice for H- ion acceleration, and comparison to PyORBIT version. 
       In TRACK, quadrupole and cavity voltage polarities were flipped. In PyORBIT, quadrupole polarities were 
       flipped, and RF gap phases were shifted by 180 degrees. Optics generally agree between TRACK and PyORBIT 
       simulations for both protons and H- ions, with some mismatch in the radial defocusing from RF fields contributing 
       to the overall mismatch in beam size.
     - Working with summer student Madeline Clyburn to get set up to work with PyORBIT.
 Next two weeks (June 10 - June 21)
     - Getting the updated versions of linac accelerator nodes in PyORBIT to work with the JLEIC ion linac lattice. 
       These modules contain more advanced RF gap models. Have reached out to Andrei Shishlo at ORNL for some guidance.
     - Implementing DTL sections into the PyORBIT lattice.
     - Start designing a stripping chicane for the lead ion linac.
     - Working with Madeline to start looking at relative velocities of H- ions along the superconducting linac to estimate 
       H- intrabeam stripping losses per unit length of the beamline.

  Previous two weeks (May 27 - June 7)
     - NAPAC2019
         - Finished and submitted the abstract of the paper “Simulation of Transparent Spin Experiment in RHIC” 
           and JLab JaCow for 2019 North American Particle Accelerator Conference. 
     - "CASA BeamBeam"
         - Optimized and accelerated the transformation parts of “Crab Kick” of “CASA BeamBeam” codes by Using “Thread” 
           of Python3 and Numba JIT method. 
     - pyFMM
         - pyFMM is in testing process. In future, if possible, we wish to develop pyFMM to deal the irregularly shaped 
           bunches in the interactions when crabbing. 
     - Particles Spin
         - Form RHIC original snake setting, we are starting to check Twiss w/o error and to track spin in one turn by using Zgoubi.

Andrew Hutton

  Previous two weeks (May 27 - June 7)
     - Attend JLEIC meetings.  
     - For the Isotope Program I held a successful brainstorming session on the target holder (the raft) design.  
       On Monday, I was asked to give a talk to HUGS on the program but I had not given a talk for a long time.  
       Spent 2 1/2 days preparing a talk (attached) and delivered it.  
     - Sarah arrived last week for the summer.  I spent time getting her settled and answering questions.  
       Her topic for the summer is to take the existing WiFEL gun, which was optimized for low-charge, ultra-low 
       emittance, short bunches) and examine whether it can be tuned to produce high-charge, long bunches.  She is 
       learning GPT for this.  
     - ALCC meeting (6/7) - apparently the ILC is not yet totally dead 
  Next two weeks (June 10 - June 21)
     - Focus on readying the LERF for beam and launching with Sarah
     - Vacation
