   Previous two weeks (Aug 16 - Aug 27)
     - Laser particle counter: Continued system debugging, optimization, and data analysis to better understand the operational modes and system variables that can be adjusted for best performance. Vendor visit on 8/19 to start pass/fail test, with current goal to obtain over 90% event detection for 80 um wire sweeping events - still discussing with the vendor on acceptable specifications on false positive event rates. Prior to and during the 8/19 visit, channels 0 and 1 could not be adjusted to give clean event signals using methods that improved SNR for other channels - the sensors for these channels are part of the initial batch and the vendor has decided to replace these sensors before continuing with pass/fail testing. The vendor has also returned the passive optical front end to their labs for fiber connector polishing. Analysis of data taken on 8/19 (wire sweeps and dropping of 50 um aluminum oxide particles) will continue, along with refinement of offline processing algorithms and methods. Will likely give an update on laser particle counter system status to the Detector Group in mid-September.
   Next 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.

Andrew Hutton

   Previous two weeks (Aug 16 - Aug 27) 
     - Isotopes:  Loida, Adam and I are continuing with the expanded search for medically interesting isotopes.  I have written up the first part, which enabled me to check on the computer output and analyze the results in detail.  This resulted in removing four of the new pathways for different reasons.  Adam Stavola is now working on getting Lila’s code working and will help to integrate it with Loida’s code.  I have prepared a set of input parameters adapted to the cases of gamma, neutron, proton and deuteron.  I am still looking for accelerators that use alpha particles for producing isotopes.  The only example I have found is the 540 MeV cyclotron at TRIUMF.  Since the DOE-ONP Isotope program is not funding this, I guess I can analyze a “foreign” accelerator in the interstate’s of completeness.        
     - ERL: The ERL sub-Panel and ERL Roadmap panel is ramp up activity after the summer vacations.  At the second meeting of the ERL sub-Panel, , Kaoru Yokoya presented a first look at the luminosity of the ERLC.  He was quickly interrupted by Reinhard Brinkman who pointed out that we cannot consider the linac and damping rings separately.  Because the electrons and positrons are returned to the damping rings, damped over 400 turns, and then reused, we have to consider the whole facility as a kind of loop.  So we need the momentum compaction factor, transverse tune, chromaticity, synchrotron frequency, etc.  I wrote an email to Valery Telnov, got it approved by the members of the sub-Panel, and sent it to Telnov asking if he had considered this and asking if he could supply any additional input.    
     - Lila and Loida: I am advising both of them for their graduate studies.  Lila wishes to pursue medical physics and I put her in contact with Thia Keppel and Ethan Balkin (who was a medical physicist at the University of Washington before moving to the DOE-ONP Isotope program).  Loida wishes to pursue accelerator physics, and I am helping her choose a University.  Coming from Puerto Rico, she hates the cold, which does limit her options!                          
   Next two weeks (Aug 30 - Sept 10)  
     - Isotopes: Loida has completed a run with 20 MeV protons - the typical energy of a hospital cyclotron.  She has identified two known production pathways for 18Fluorine and 119Antimony.  This confirms that the program is performing correctly.  More interestingly, she identify three other possibilities: 55Cobalt, 76Bromine and another pathway to 119Antimony.  I am working on looking at the other radioisotopes that are co-produced and which could be dangerous.  The 56Fe (p,2n) 55Co reaction seems clean with a small production of two Manganese isotopes that should be easily separable chemically.  The 76Bromine is more complicated as there are many byproducts and this pathway may not be viable unless the target 76Selenium is isotopically purified before irradiation.  There are similar problems with the alternative pathway for 119Antimony, which may or may not make it unacceptable.  Loida is now working on getting the neutron production working.  The goal is still to identify pathways for all the medically interesting isotopes called out by the DOE Isotope program.      
     - ERL: The sub-Panel has has another meeting and will now move back to weekly meetings for the next month to finish.  We already have ~20 pages written and will probably expand to ~30 pages before we are finished.  The short answer is that neither is in a state that it could replace the ILC or the FCC-ee.  We will come up with a list of R&D items that should be pursued to make these ideas achievable.  For me, the most important is operation of the cryomodules at 4.5K to reduce the cryogenic plant construction cost as well as the power requirement.  This should be an area where Jefferson Lab invests heavily - the pay-back would be enormous as it would also enable every university to envisage having a small superconducting accelerator for Compton back scatter, etc.       
     - SuperKEKB Review: this was help remotely September 2, 3 with the closeout September 6.  This was four hours of presentations, but ht long version of the talks had been posted a few days earlier.  They have obtained a new luminosity record (~50% above their KEKB record) but have a lot of problems with beam blow-up, backgrounds, catastrophic beam loss (damaged collimators and detector modules) and a variety of problems that are intertwined which makes understanding extremely hard - for them as well as the committee.  They have created an international task force to address some of the problems; we recommended that they expanded the number of topics.  Many labs have people who have agreed to help.  They are mostly designing the next generation colliders and SuperKEKB gives them a chance to hone their skills, benchmark their codes and improve the design of their own machine.  We would be wise to do the same with the EIC.
