Amy Sy

   Previous two weeks (Aug 19 - Aug 30)
     - 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)

   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.

Joe Gubeli

   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.

CASA Fellows
LERF - Steve Benson

   Previous two weeks (Aug 19 - Aug 30)
     - Worked on addressing questions for Pre-CDR
     - Started putting together talks for ERL 2019
     - Hosted talks for Steve Jamison and Stephen Webb
     - Tried to get gallium shipment to VCU but rant into technical difficulties
     - Reviewed GTS gun paper
     - Worked with TJS Technologies on LOI for ERL merger deflector cavity.
     - Worked with Joe Grames to come up with required upgrades for LERF injector.
     - Reviewed sensitive information with Brian Hanlon.
   Next two weeks (Sept 2 - Sept 13)
     - 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
     - Completed talks for ERL 2019
     - Finalize documentation for isotope ERR




Andrew Hutton

   Previous two weeks (Aug 19 - Aug 30)
     - Finished up editing the PreCDR-100, but I am sure it will be coming back at me!  
     - On Friday, I met with Camille to give her some “insider” information on her new position.  
     - More interestingly, I had a telephone conference with Doug Wells, our isotope collaborator, presently at New Mexico Tech.  He has a follow-on patent being prepared on a
       new technique for producing radio-isotopes, which he would like us to demonstrate.  His office sent us a non-disclosure agreement, but I have not heard back from Rhonda
       Scales if this is acceptable to JLab, so I don’t have the details.  I suggested that he passed the basic concept by Ethan Balkin to find out whether this would be
       something that the DOE-ONP would support (financially, of course).  I looked at the previous patent and it is really interesting, but it is a new way of producing isotopes
       that are already being produced by industry, so I am not sure that the DOE Isotope program will want to fund it (although they should).  I will keep you informed.  
     - I have also been preparing an introduction to the Isotope Program for the as-yet-unscheduled ERR.  I am certain that they will need an introduction, but I don’t have a
       handle on the rest yet.  We are having some difficulty with the isotope target approval, it needs a pressure vessel review which is going slow.  But we will work through
       that. This afternoon, we are meeting to discuss the details of a transfer of unirradiated gallium to VCU via FedEx; lots of details to work through, e.g. does it stay
       liquid? If not, will it freeze and burst the crucible, etc?   More fun than all of the bureaucratic hurdles we have to jump over.  
     - I have been emailing back and forth collecting information on future NP projects world-wide for the AMICI conference mid-September. This will move to high priority in the
       next two weeks.  I should probably give the talk at a CASA meeting when I get back.    
   Next two weeks (Sept 2 - Sept 13)
     - Vacation: 6 days
