       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.

       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.  
   Next two weeks (Aug 5 - Aug 16)
     - Personal leave

   Previous two weeks (July 22 - Aug 2)
     - HPWS: Attempted to use the new dynamic tuning toolbox to find better servo and current loop parameters for the
       linear motor. This didn’t go well. In order for an expert to help me remotely with this tuning the controls laptop
       was SW upgraded and placed back on the network. This will allow me to share the controls screen during a web
       meeting.
     - Isotope: The alignment of both the radiator aperture and the target is complete. The S4 block and 25 steel plates
       were placed on the slide for the movable wall. Happy to say that the little motor to move the current ~2500 lbs
       works well. The wall moves with no trouble.
     - FAST: The LDRDS has been dissembled, the silver plate HW replaced, the new gimbal plate and viewer assembly
       installed. The chamber is under vacuum and everything is loaded into the Pelican cases for transport. The two cases
       are now in Shipping and Receiving.
   Next two weeks (Aug 5 - Aug 16)
     - HPWS: Work remotely with expert to tune the motor parameters. Test long encoder cable.
     - Isotope: Help with models for radiation simulations. Run some thermal simulations. Add cooling and diagnostics to
       the shield wall.
     - FAST: Travel to Fermilab to help with assembly and install. Take some online training to work there.
     - IBIC: Write my section of the paper & poster.

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.
