Amy Sy
Previous two weeks (July 22 - Aug 2)
- 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.
- Continued work on the stripping chicane optics design and matching to the stripped beam distribution.
- Continued work with PyORBIT including: troubleshooting the DTL linac implementation and lack of beam stability, and
optimization of the superconducting portion of the linac for better matching with TRACK. Also plan to discuss with
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.

Andrew Hutton
Previous two weeks (July 22 - Aug 2 )
- July 22- July 29: primary focus on the isotope project
- July 22: visit to VCU to test out our designs for the crucible removal and opening using a remote manipulator. It
was successful, but several opportunities for improvement were noted , and have since been made by Kevin and Joe.
- July 22 - July 26: visit by Robert Bentley and Geno Santistevan, PhD students at New Mexico Tech. They attempted
to make thermal measurements (a bust) carried out FLUKA calculations to determine the amount of radiation
immediately following the irradiation and following the decay. We have tentatively changed our irradiation
protocol for 10 hour cool-down time rather than 24 hours initially proposed. This enables us to extend the
irradiation time for more Cu67 production.
- July 26: the quarterly report for the isotope project was submitted to the DOE on time.
- July 29-August 2: Read large portions of the pCDR-100 and made corrections, mostly English but some substantive
comments. Also spent a lot of time with Sarah who finally got GPT running on the WiFEL Gun. Sarah presented at
the Friday lunchtime poster session and had a lot of interactions with people (who would be surprised?).
Next two weeks (Aug 5 - Aug 16)
- Focus on nailing down the Isotope run and helping Steve finalize the safety documentation.
- Continue the pCDR editing
- Help Sarah really make progress on the WiFEL simulations.
