     - Worked with summer student Madeline Clyburn to extract transverse and 
       longitudinal rms velocities along the linac for H- intrabeam stripping estimates. 
       Currently able to extract information about the bunch at the end of the linac, and
       working to extract values as the linac is traversed. 
     - SRIM/TRIM calculations of energy and angular distributions of lead ions after passing
       through carbon stripping foils, and parameterization of the probability distribution 
       as a function of foil thickness and incident beam energy as in the Gorelov and Marti
       paper TUP087 from LINAC2006. Generating python tools to analyze the SRIM/TRIM data and
       extract distribution parameters - general agreement when comparing results obtained for
       12 MeV/u U-238 ions.
   Next two weeks (July 8 - July 19)
     - 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.
     - Putting together a stripping chicane in TRACK; estimates of effects of carbon stripping foil
       on lead ion beam emittances and optics parameters.

   Previous two weeks (June 24 - July 5)
     - In the last two weeks, the isotope program has had successes and failures.  We
       attempted to bring CW beam to the existing 1G dump.  We achieved bringing pulsed tune
       beam into the 1G line, but not to the end.  A series of hardware problems prevented
       full transmission, including badly mounted view screens that dropped into the beam,
       etc,  We will try again in a couple of weeks.  Kevin has made progress on the boron 
       nitride crucible, almost ready for prime time.  Jamal Zweit has received the remote 
       manipulators for the hot cell at VCU.  Kevin and (hopefully) Keith Welch will go up to
       VCU to make sure that the crucible (with a piece of iron in it to mimic the weight) can
       be extracted from the pig and be opened by the remote manipulators.  I am preparing the
       quarterly report which will be fairly positive.  
     - Attended an ALCC videoconference on the organization that the US delegation wants to 
       propose for the ILC Laboratory implementation.  Not sure I am fully convinced that the 
       ILC is going to happen, but I will continue to do my bit.  
     - I have spent some time with Sarah, we need to make sure that she gets to the meat of
       what we would like her to produce.  
     - I understand from Stuart that there will be a meeting tomorrow to discuss the ODU 
       proposal to the Virginia Legislature (which includes the JEDI Proposal).  I don’t have 
       a good feel as to whether it will be successful.  
   Next two weeks (July 8 - July 19)
     - I will be in Japan for the SuperKEKB Review.  When I return, I will be working on 
       completing the Isotope Quarterly Report, and helping Sarah, who should have got
       sufficiently far advanced with GPT to start optimizing the WIFL gun for high bunch
       charge.  
     - I will start editing the PreCDR100 when there is something for me to work on.
