Isurumali Neththikumara

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

Joe Gubeli

    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.
