Max Bruker

  Previous (Feb 15 - Feb 26)
     - More optics measurements
     -	Finish JSPEC improvements if there is some free time
     -	Simulate multipole moments of the commercial corrector coils to be able to predict their detrimental effect, if any
     -	Simulate energy gain of QCM cavities depending on phases using tracking with field maps and accurate geometry. I've done this before but will need to resuscitate it to see if Yan's 
       and Matt's latest calculations make sense. They involve extrapolating the measured energy gain of the combined structure to zero field in one of the cavities to predict the energy gain 
       of the other cavity in isolation. I have some doubts as to the accuracy of that method because the beam becomes so slow that the transit time is likely to change significantly and we don't
       have enough phase knobs to compensate for it. Interesting question and not complicated.
  Next (Mar 1 - Mar 12)
     - HDice run. I wouldn't say it was entirely without issues, but overall we can't complain. Apart from occasional RF trips, the biggest
       annoyance is that the orbit is not constant enough by itself and you have to resteer it every few hours.

Joe Gubeli

   Previous two weeks (Feb 1 - Feb 12)
     - Isotopes – Work on 50kW design
     - ARDDOT - Completed new design for the ARC 1 & ARC 2 SLMs. This design places the cameras over the dipole. With the dipole steel and a few 30% boron poly bricks we should be able reduce the radiation on the camera and have it last a little longer. Due to the low head clearance in the upper ARC a creative modification of a turning mirror was made that should allow for remote X&Y axis steering. Everything has been ordered except the 3mm slits and the borated poly shielding. Those should go on order today.
   Next two weeks (Feb 15 - Feb 26)

Andrew Hutton

   Previous two weeks (Feb 1 - Feb 12)
     - EIC: again, not much.  I need to find a topic I can get my teeth into.  That may have to wait until the JLab deliverables are defined.    
     - Isotopes:We continue to study the foil samples that were irradiated (led by Adam Stavola), and there are still discrepancies that we do not fully understand.  Our two NMT students, Geno and Robert, have received the data and are setting up a different software package to cross-compare.  In a phone call with our funding manager, Ethan Balkin, I learned that there will be two FOAs coming out this summer; I assume one for labs and a companion one for Universities.  This breaks the pattern of an FOA every two years, and thinking back on the Ethan’s careful wording, I think he has not awarded as many proposals as usual to provide funding for the intermediate year.  If so, we were only half-punished!  The Reviews were helpful and we will work on strengthening the proposal.  I have made a request to VCU to have their hot-cell transferred to us - I give it about a 25% probability, but I felt I should ask.  Drew offered us use of a lead-shielded room on the third floor of the ARC which is currently being used by Dillon, but will be vacated as part of the ARC refurbishment.  That would still leave us with a chemical separation problem, but one thing at a time.     
     - ERLsI have spent quite a lot of time developing spreadsheets showing the various aspects of an ERL and the projects that currently hold the record, the approved projects and which aspects they will push the limits, and the proposed project (PERLE) and what it would achieve.  In parallel, I am collecting up what LHeC would need to compare with the various records to identify gaps.  Of interest, the JLab FEL still holds the beam power record, CEBAF 1-turn has the energy record, and CEBAF 5-turn will have both the energy record and the number of turns record.  It may also have the record for highest current in a multi-turn ERL for a while.  Not bad for a lab that has turned its back on ERLs!       
   Next two weeks (Feb 15 - Feb 26)  
     - Isotopes:There has been considerable progress on understanding the results of the isotopically purified gallium.  The students at NMT, with the very active participation of Doug Wells who is a real expert at this, have re-analyzed all of the data.  They managed to show that some of the data is bogus and should be ejected; the rest agrees well with the results by Adam Stavola.  This work will continue over the next two weeks to include propagating the errors to get a final error estimate.  We are all feeling much more confident now!  We are waiting for the vacuum group to have time to remove the window for post mortem (actually we hope it isn’t dead!) as we should ship it back to ANL if it is still OK.      
     - ERLS:I have made great progress on the spreadsheet, requesting updates from all of the ERLs and already receiving replies from most.  I am now mulling over which are the key parameters that should be put on the 3rd tab of spreadsheet showing how we are, or will be, progressing towards verification of these key parameters.  For your reading pleasure, I am attaching the spreadsheet so far, comments on format and content are more than welcome.     
     - I have been approached by VCU Nuclear Engineering Group to participate in a request for student funding on Isotope studies.  The other collaborators are Virginia Union University (an HBCU) and Sweet Briar College (an all women’s university).  
     - I have also been on a videoconference with Achille Stocchi to try and unblock the French bureaucracy on the PERLE ICRADA.  All I get is that there is no problem, and a promised date (February 26) when we will have the PERLE Collaboration Meeting.  However, it is the French spring holiday season (usually devoted to skiing, but the ski resorts are all closed).  Getting anything out of French bureaucracy in a vacation period seems doomed to failure.  But we will see. . . . . 
     - I initiated an email chain on the availability of an American SRF cavity supplier, proposing that the Department of Energy, Office of Accelerator R&D and Production pay the upcoming projects (including the EIC) to buy American, including taking on some of the risk.  I see that there is now an RFI on this.
