Joe Gubeli

   Previous two weeks (Aug 17 - Aug 28)
     - Isotopes –Attended several planning meetings. Setup some equipment needed for next week’s run
     - ARDDOT - Had a few meeting with the Injector group to determine if the new viewer image design would work for them. They have some
       very tight spaces. Met with the I&C group to show them the viewer imager and to test a lipstick replacement camera. The tested camera 
       has an nonadjustable lens an images a lot of the tube with a small image of the view screen. Not sure that it is a good replacement. The
       I&C folks had to run to another call and didn’t have time to assemble an imager. We will reschedule for another time. Have inventoried
       and conveniently placed all the parts received for the imager. Still have a few parts including the cameras that have not arrived.
   Next two weeks (Aug 31 - Sept 11)
     - Isotopes – Help as much as possible with the upcoming experimental run.
     - ARDDOT – Work with I&C on imager assembly
     - ACCTVL – Attend the virtual IBIC2020 Conference.

Andrew Hutton

   Previous two weeks (Aug 17 - Aug 28)
     - I was on vacation the week of August 17 - 24.  
     - This week I started to look over the EIC CDR for a second time; I also attended several EIC meetings.  
     - I participated in a VNECA meeting and sent an email to Stuart and Andrei regarding the draft “Virginia is Nuclear Strategic Plan 2020-
       2024” which I also forwarded.  
     - I also participated inn an early morning videoconference with Stuart, Andrei, Achille Stocchi (Director of IJCLab), Max Klein and Oliver
       Brüning regarding PERLE.  The Europeans made a concerted effort to convince Stuart and Andrei of the importance of Jefferson Lab 
       involvement in PERLE, perhaps with some success.  In addition, I have been answering questions from the DOE regarding the PERLE ICRADA 
       (Jessie Tenbusch has been an enormous help in this).  
     - I have prepared a request to the Experiment Review Committee to carry out a calibration run in addition to the irradiations already 
       partially approved.  Interesting new fact: there are now two FLUKAs;  FLUKA2020 from INFN and FLUKA 4.0 from CERN.  We are trying to 
       find out if they are the same or different!  
     - I missed the meeting on the organization of a Linear Collider Workshop while I was on vacation; I distributed the information to Stuart,
       Andrei, Mike Spata and Todd.  
   Next two weeks (Aug 31 - Sept 11)
     - I attended various EIC meetings.  I also spent some time studying the draft report from the Alternate Strong Cooling Task Force. This 
       resulted in a suggestion to Geoff and Fanglei to shorten the high energy section of the dual ring cooler; I sent the same recommendation
       to Jorg Kewish for the single ring cooler.  I proposed a method to arrange the cross-over between the high and low energy sections of 
       the dual energy cooler using twin-axis SRF cavities.  Finally, I suggested to Jorg that he modify the wiggler design he developed for 
       the single ring cooler to be compatible with the high energy section of the dual axis cooler ring.  
     - The modified (and much improved) PERLE ICRADA was sent to the DOE.  
     - We have been making detailed plans for the Isotope Irradiations, scheduled for September 13 - 19.  
     - I have been active on the AWLC 2020 organization, proposing three talks from Jefferson Lab, which were accepted.
