   Previous two weeks (Feb 17 - Feb 28)
     - H- intrabeam stripping estimate in JLEIC ion linac using PyORBIT. Cleaning up of the lattice model used by M.
       Clyburn to split the superconducting RF cavities to incorporate three gaps versus a single gap per cell.
       Calculations of the H- intrabeam stripping cross-section as a function of the relative beam velocity. First
       pass at calculating the fractional beam loss as a function of linac length.
     - Longitudinal Schottky signal analysis for the IMP cooling experiment including dithered electron beam data.
       Dithering the electron beam by 100 - 1000 Hz at different electron and ion bunch lengths generated more
       sidebands in the cooling process that persist even in the later stages of the cooling duration. Additional
       satellites at the dithering frequency are sometimes seen in the spectra, but not for every parameter set, so
       conclusions on general behavior are difficult to make. Focus will be on the fixed frequency data for the
       resultant publication.

Joe Gubeli

   Previous two weeks (Feb 17 - Feb 28)
     - Isotope Experiment – Reinstalled the camera that images the alignment target after another RADCON mock
       run. Prepare for next week run.
     - Halo monitor – The missing $27k was returned to Radiabeam. They have asked guidance on how to wire the
       funds to us but nobody seems to be helping them. Not sure we will ever see it.
       routine code and the funds went to the State Department instead of DOE.
     - ARDDOT – Preparing an installation manual for the CEBAF Viewer replacement. Took sometime this week to
       clean up Lab 2 after quarterly safety walk through remarks.
     - HPWS - Had some meetings to decide on functionality of the controls and GUI.
     - Safety - Had the Quarterly as well as the Monthly Saftey LERF inspection. Housekeeping and low
       illumination was the only concern. Housekeeping was remedied and FM is working the lights.
   Next two weeks (Feb 17 - Feb 28)
     - 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 – Continue working with Zemax. Start working on a couple of different optical designs that will
       allow the cameras on the CEBAF SLMs to be in a lower radiation environment. The current beam setup in CEBAF
       allows for much higher production of radiation at the detriment of the electronics in the tunnel.
     - Isotope Experiment - Support 1kW run.

Andrew Hutton

   Previous two weeks (Feb 17 - Feb 28)
     - EIC, participated in some meetings, I am unimpressed!  I also have been advising Yuhong about a different
       parameter set with more, smaller bunches.      
   Next two weeks (Mar 2 - Mar 13)
     - EIC, Michelle Shin and Manouchehr were visiting today and Mike Spata told them about my proposal to change
       frequency to 800 MHz.  I met them both at lunchtime so I got the chance to do a sales pitch.  They were
       receptive - particularly with regard to ONP being the contact for the future CERN SRF, not HEP!  So when
       there is an explosion from BNL about DOE knowing about the frequency change proposal, it wasn’t me!  I 
       attended a video conference on SRF where the enormous problems caused by the few, big bunches were discussed.
       I think they would be very receptive to a change in the operating mode that distributed the charge more 
       uniformly.  
     - Isotope preparations continue.  We heard today that Jamal will not be able to accept the crucible until his
       new lab is set up - and we have no date for that.  I am maintaining the 1 kW run and will move ahead to use
       the data to prepare for a 5 kW run, perhaps sometime in April.  
     - I participated in VNECA which is now focusing on generating a strategic plan for nuclear energy in Virginia.
       I can’t participate in preparing the plan, but they would welcome someone from JLab.  
     - I am in the process of canceling my trip to AccApp 2020.  A clear instruction from DOE forbidding foreign
       travel would be most helpful in getting reimbursements.  
     - I signed up for HPI training next week - did you know it is two mornings, 2 1/2 hours each?
