            initiated with operators during tuning of the accelerator this round.  It became clear that with the Spreader
+
            matching quadrupoles "on design," empirical adjustment of the defined envelope tuning knobs of the previous
+
            Recombiner to make the viewer spots of the following recirculation arc most alike was a protocol which matched
+
            the beam across the linac in a "best practically achievable" sense.  This provides minimally perturbed beam
+
            optics across the linac and through the Spreader, minimizing time in execution to make the qsUtility scans and  
+
            re-match through the Spreader.  Boron Nitride NanoTube material, as recently installed at viewer ITV7A09, may
+
            also provide a sufficiently well-resolved image of the beam (although invasive in image acquisition) to serve
+
            this purpose. This may be a feasible alternative to distributing SLMs throughout the arcs, sidestepping the
+
            characteristic blooming limitation of the original ChromOx viewer material which has prevented application of
+
            the original (late '80s) design intent of using the viewers in this way.

     - Distribution mapping for pre-strip to post-strip lead ion distributions based on parameterization from TRIM 
       simulations.
     - PreCDR updates to ion sources and ion linac sections, particularly updating the ion linac section of Chapter 5. New
       end-to-end simulations for all three linacs and updates to the preCDR text to reflect the simulation results.
     - H- linac optimization in TRACK; end-to-end simulations for the 150 MeV linac result in ~100% emittance growth in
       the H- beam, so optimization is in progress to improve on this emittance at the linac exit. Also implementing 
       alternating polarity in the solenoids of the accelerating cavities, in case of acceleration of vertically-polarized
       ions.
   Next two weeks (Aug 5 - Aug 16)
     - Continued work on linac optimization for reduced transverse emittance.

       ANL the possibility of converting the RF cavity field map files from binary Fortran files to something that can be
       read into PyORBIT.

He Zhang

   Previous two weeks (July 22 - Aug 2)
     - Cooling code development - Added synchrotron oscillation in to sweeping effect simulation. In the sweeping effect,
       each time step still covers many synchrotron oscillation periods. So I just give a random phase advance to each ion
       to represent the synchrotron oscillation. After taking this oscillation into account, the sweeping effect still
       works but becomes weaker. Another thing to notice is that the proton velocity distribution is swept to one end
       without the synchrotron oscillation, while it stays in the middle with the oscillation.   
     - Beam-beam effect - Following Ji’s example, I add the C++ code of map-based symplectic tracking to BeamBeam3D. The
       files compile well but I always get an MPI error when running the executable file with mpirun. Tried to compile
       Ji’s original code and got the same error. I suspect this is not due to the new code. I am asking for help from Yun
       and Ji. 
     - IBS calculation - We have received the lattice of eRHIC and  their ion beam parameters. I have picked up one set of
       parameters and calculated the IBS time, which agrees with their calculation.
