     - Continued H- linac optimization in TRACK. Rough linac optimization using MADX for optics design through matching sections between different components in the linac (i.e.
       matching from DTL tanks to SCL section). Transferred one version of "optimized" H- ion linac lattice to PyORBIT for comparison with TRACK - trying to understand 
       disparities between TRACK and PyORBIT simulations to best implement processes that are harder to do in TRACK, such as simulation of emittance growth through a stripping
       foil.
     - Working on PSTP2019 invited talk titled "Laser-driven polarized deuterium source". 
   Next two weeks (Sept 2 - Sept 13)
     - 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 PSTP2019 talk

   Previous two weeks (Aug 19 - Aug 30)     
     - Beam-beam effect - After inserting our symplectic tracking code into beambeam3d, the codes compiled successfully. However, me met some memory fault when running the 
       code. I tried to solve this issue and did fixed a few small bugs, such as a overflow of integer for factorial calculation, but the bug is still there. This work was put
       onhold since NAPAC posters/papers are due. Will continue in the next week.  
     - IBS calculation - We are benchmark our IBS rate calculation with others. After a few iterations, I think when we use the same formula and the same parameters, our
       results agree with BNL’s result. Meanwhile,  we noticed that even if the beam parameters are very close, our IBS time is about four times longer than eRHIC’s. But why?
       We suspect it is the lattice that leads to this difference. Next week we will investigate it. 
     - NAPAC - Prepared slides for a talk in SERIPO workshop. (Yuhong will present.) Prepared two posters. Writing two papers but haven’t finished them. 
   Next two weeks (Sept 2 - Sept 13)
     - Finish NAPAC papers. 
     - IBS analysis.
     - Start working on JSPEC benchmarking with Lanzhou experimental data.
     - Finish BB3D debugging.

   Previous two weeks (Aug 19 - Aug 30)
     - HPWS: New motor controller for the High Power Wire Scanner arrived. After some change in the wiring I was able to run some initial test. The new controller seems to run
       a little better than the older one but the parameters are not yet optimized. Had a telecom with our collaborators, Radiabeam, were we both tried to tune the parameters.
       After a little progress we decided that we need to get Aerotech involved.
     - Isotope: Little to no work on Isotope production
     - FAST: Received the slit plate and had it UHV cleaned. Had a trip scheduled but the folks at Fermilab realized at the last minute that they had a scheduling conflict with
       the cleanroom. The trip has been delayed to the end of September at the earliest.
     - IBIC: The paper and poster are completed. Waiting on local review/approval to submit the paper.
   Next two weeks (Sept 2 - Sept 13)
     - Short week with Monday being a holiday and Friday a travel day to IBIC. Will work some on preparing the Isotope crucible with gallium test shipment. The idea is to keep
       the gallium from freezing during transport. We will try using hand warms packed in the shipping container. It is the start of the month so I will be doing the monthly
       safety walkthrough as Safety Warden. The following week is the IBIC conference.



Michael Tiefenback 

   Previous two weeks (July 22 - Aug 2)
     - Vacation interleaved with remotely addressing HPS and magnet system configuration
   Next two weeks (Aug 5 - Aug 16)
     - Vacation leave plus dealing on-site with HPS and magnet system configuration issues


CASA Fellows
LERF - Steve Benson 

   Previous two weeks (Aug 5 - Aug 16)
     - Completed chapter 6 for Pre-CDR
     - Hosted seminar for Grigory Eremeev
     -	Arranged for assembly of the LDRD at Fermilab
     -	Helped to prepare paper for EIC description for NAPAC
     -	Consulted with Chris Hall from Radiasoft on a possible SBIR for the EIC cooler.
     -	Set up seminars for Steve Jamison and Steve Webb
     -	Attended SBIR meeting in Gaithersburg, MD
   Next two weeks (Aug 19 - Aug 30)
     - Submit proposal for change of SOW for the Cooling FOA for IMP work
     -	Explore the possibility of changing the venue for the no-deflection merger test
     -	Finalize documentation for isotope ERR
     -	Start putting together talks for ERL 2019
     -	Host talks for Steve Jamison and Steve Webb



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.
