Amy Sy

   Previous two weeks (Aug 30 - Sept 10)
     - Laser particle counter: Data analysis of pass/fail testing data taken during last vendor visit. Implementing new algorithm at vendor suggestion that calculates local peak to peak amplitudes in both the amplitude and phase data, and sums the two signals together for improved event detection. Continued algorithm optimization by varying moving window size in the peak to peak calculations, as well as low and high pass filtering effects. Studies of dynamic window and dynamic averaging implementation in data processing applications. The newer 18 sensors have met pass/fail specifications, but the full 24 channel system is incomplete until the initial 6 sensors can be replaced with upgraded versions. The vendor has committed to supplying these upgraded sensors as replacements for the initial 6, and have been authorized to begin work on 24 additional sensors for a full 48 channel system. Delivery of the remaining 6 upgraded sensors for further testing is anticipated in the late September to mid October time frame.
   Next two weeks (Sept 13 - Sept 24)
     - Laser particle counter: Found a bug in the data-taking software that erroneously saves one extra bit to random data arrays - vendor has confirmed that this is a software issue and is working to understand why it occurred and how to prevent this in the next version of the GUI. Summarizing current progress in advance of taking extended leave. Preparing content for update on laser particulate counter status at JLAAC in November/December time frame. Vendor anticipates returning with full 24 channel system the week of September 20-24 for continued testing.

Andrew Hutton

   Previous two weeks (Sept 13 - Sept 24) 
     - Isotopes:  I went over Loida’s 20 MeV output data and identified another medically interesting isotope Bromine77, which is not on the DOE list but has been used in the past.  Both Bromine76 and Bromine77 would be produced from isotopically purified Selenium, which has one problem.  The melting point of Selenium is 221°C, which means that it cannot be in the form of a stand-alone foil.  I envisage encapsulating it in Titanium(?) like ANL does with their zinc targets used to produce Copper67.  The range of 20 MeV protons is ~1mm in Selenium, so it would be a thin disc, the size of a US quarter.  Our UVA collaborators tell us that separation should be easy as bromine is volatile.           
     - ERL: I wrote a draft of the conclusions of the ERL sub-Panel, which initiated an email storm.  Eventually, all the members with one exception agreed on a more nuanced version that I will produce in the next few days.  Getting a unanimous conclusion will take some effort!  The hang-up is whether operation at 4.5K with high Q0 would bring the cryogenic load for the ERLC version of the ILC sufficiently low to be competitive as a future upgrade.  We will need some careful wording to be able to come up with a report that everyone accepts.  The ERL Panel has now two weeks to complete the first draft of the actual roadmap, complete with cost and schedule estimates.  The upcoming few weeks are going to be extremely busy.         
     - PERLE:  I have been in contact with Wim Leemans at DESY ( a long-time friend) about DESY joining PERLE.  We will have a high-level meeting between the PERLE inner circle (Walid Kaabi, Max Klein, Hans Weise, and perhaps Achille Stocchi) this week to discuss the opportunities.  This is also intended to try and bring DESY into the ERL Roadmap, which would strengthen it considerably.  The ICRADA is slowly going the rounds - I don’t know where it is stuck it this moment, but resolution should be near.  I also got in the middle of unblocking the collaboration with BINP as the Director used to be my student.  I continue to have concerns about the role that Jefferson Lab is willing to play in PERLE, but until the ICRADA is signed, I don’t think it is worth bringing the matter up to Stuart. 
     - I attended a meeting of the ALCC, where the latest news from Japan is not good.  MEXT has decided that it cannot approve the ILC Pre-Lab until other countries have signed on.  However, the other countries are waiting for a clear indication of intent from Japan.  The Japanese solution - create another review panel!  The ALCC is normally very positive about the chances for the realization of the ILC, but were distinctly disturbed by the news, which was presented by Hitoshi Murayama, a very credible source.                             
   Next two weeks (Sept 27 - Oct 8)  
     - Isotopes: Loida has now completed the thermal neutron production and reformatted it to make it easier to search.  Surprisingly, out of 70, 179 reactions, only 31 were interesting.  I will come up with the average energy of “fast neutrons” in a reactor for her next search.  In the meantime, Lila is going back and re-formatting the outputs from the gamma and proton searches.          
     - ERL: this has been a busy couple of weeks.  The first draft of the ERL sub-Panel report is almost complete.  Jean Delayen brought up a new effect; with counter-rotating beams in twin-axis cavities, the only way to have both beams on crest is that the cavity spacing is maintained at exactly an integral number of half-wavelengths - hard to achieve during cool-down warm-up and seasonal expansion/contraction.  I explained why I didn’t think this was a problem, and this is now grown into an email back and forth!  Will let you know the outcome.  After we finish the draft, it will have to go to Thomas, Vladimir, and Valery Telnov so they can object - I am expecting fireworks from at least one of them!  The ERL Panel presented the initial findings to the LDG; I think we did quite well.  Now we have to finalize the budget estimates and milestones by October 12.  Again a crisis.        
     - PERLE: We met with Hans Weise of DESY to discuss possible involvement in PERLE; they claim to be saturated, and are not willing to think about working on any other frequency that 1300 MHz - so they are basically abdicating from future high-energy high current colliders.  We were flabbergasted!  After a fair amount of back and forth, BINP has signed the collaboration agreement with PERLE. They will provide magnets.  That still leaves JLab out in the cold.
