Joe Gubeli

   Previous two weeks (Mar 2 - Mar 13)
     - Isotope Experiment – Spent a large portion of the last two weeks on this project. Started with support of the 1kW run which
       had to be terminated early to investigate the solid hBN target that developed a crack. We had discussions on the cause of the
       crack as well as a path forward. Going forward we decided to investigate the use of graphite over hBN due to its better thermal 
       and electrical conductivity. I performed some analytical energy loss and absorbed power calculations on the window, radiator and
       target. Three targets were analyzed, solid hBN, solid graphite and gallium filled graphite. Using these numbers I ran a number of 
       simulations of these three cases plus a few more using different material properties. I made a presentation of the results.
     - Halo monitor – – The missing $27k received by JLab. We are working on creating an account code for these funds
     - ARDDOT – Started investigating a new design for SLM1A09 to place the camera over the dipole. The idea is to use the dipole
       steel as additional radiation protection. 
     - HPWS - I created an analytical as well as a sequential Zemax simulation of the optics use to image the wire as well as 
       collect photons into a photodiode.
   Next two weeks (Mar 16 - Mar 27)
     - HPWS – Design a test setup to pulse a diode laser that simulates the electron beam. This will allow us
       to test the scanner’s acquisition in pulsed mode. 
     - ARDDOT – Build first a sequential Zemax model of the new SLM1A09 optics then move to a non-sequential Zemax model. After 
       completion of the Zemax models create a solid model and then prepare a presentation for review.
     - Isotope Experiment - Support 1kW run.

Andrew Hutton

   Previous two weeks (Mar 2 - Mar 13)
     - I visited Jamal at VCU to find out more information on the hot cell we need for Isotope separation.  Jamal has been 
       shut down by their Radiation Officer until the hot-cell has been relocated.  The future location has been secured.  However, with
       the coronavirus, I do not expect any rapid resolution of the problem.  
     - We carried out our first irradiation in the hutch, unfortunately fracturing a solid block of boron nitride used for setting up CW
       beam (I have described this in detail in other correspondence, I will not belabor it here).  The Isotope team is preparing for a
       supplemental ERR as we are considering changing the crucible to graphite.  A suitable graphite grade has been identified and a 
       dozen blocks ordered (Kevin).  We all received measurements of the residual metallic impurities, which are being looked at by
       RadCon for completeness (Keith).  The NMT students are on Spring Break and have ramped up thermal simulations, which are being
       compared to our simulations (Joe). 
     - I participated in a VNECA meeting, which was unusually interesting as we are trying to address the major changes in energy policy
       enacted by the Virginia legislature (again, I reported on this in a separate report).  
     - I completed my HPI training.  Overall, I was not impressed, the trainer spent too much time pointing out mistakes made at 
       Jefferson lab in the past (totally against the principles of HPI).  
     - I attended a meeting of the EIC RF group discussing HOM losses in the electron ring SRF cavities, but did not contribute much.
       Bob and Frank know way more than I ever will.  I have also interacted with Vasiliy and Yuhong on increasing the luminosity in the
       medium energy region.  
     - I provided advice to Alex and Deborah about the Awards and Prizes Committee which I initiated, was not maintained, and which Alex
       is now willing to take on.  I stressed that this initiative will only work if Stuart mandates the team.  
     - My week ended with a request to self-isolate until further notice.  
   Next two weeks (Mar 16 - Mar 27)
     - I am now working from home, for which I am well equipped.  
     - I will be following up on the isotope preparations.
     - I will work through the luminosity parameters in the eRHIC pCDR and have already found some errors.
