       - QCM energy gain puzzle solved. It only took me 24 pages of writing and the corresponding amount of simulation effort to discover that one of the field probe amplifiers was clipping at high levels and a select few had known about it all along and had deliberately set it up that way. People don't talk to each other, it seems like, because other members of the RF group had vehemently rejected the idea until we remeasured it. It was a fun academic exercise, though, and I got to convince people of the merit of doing simulations in parallel to commissioning. It's also possible they think I'm a pain in the butt, who knows.

      - Prebuncher studies are consistent with Alicia's and Reza's results in terms of field vs. focal length, and also consistent with Haipeng's results in terms of field vs. input power for the most part. We believe the RF system is well-understood, so I believe the only thing that might cause the results to deviate from our simulations is of a more complex particle-kinematical nature, i.e. something to do with space charge. I do not expect such issues to cause a power deviation by a large factor, so my current assumption is that the whole confusion is a result of miscommunication and inconsistent documentation. We shall wait and see.
−
       - CEBAF MAC certification. It's already done as of today but technically belongs into this period of time.
+

       - The Prebuncher Mystery may have been solved, too... Some more discussion may be needed, but I think I understand the problem at a modeling level. A few pages of simulations results have been written.
+
       - IPAC poster + video + paper done
−
       - Now, time to prepare the IPAC material.
+
       - I repeated some simulations of the emittance growth in the IMP experiment with phase dithering to make sure they all use the same, most recent tracking code. Unfortunately, the result does not agree with reality anymore! This may be something to study at a later point. For now, I left the dithering results out of the IPAC material.
 +
       - We wanted to start beam commissioning of the CEBAF injector upgrade this week, but it was delayed by a series of unfortunate circumstances.

This requires some non-conservative process in between the magnetized beam transform and the Brown-Servranckx transform - currently investigating the possibility of using space charge to facilitate this. Looking into the space charge modules in PyORBIT for applicability. The TRACK code doesn't appear to accept arbitrary matrix inputs for beamline definition, so is harder to work with for these purposes.

     - CEBAF MAC certification completed
     - Application and interview for CIS SS1 position completed
     - Prebuncher studies are consistent with Alicia's and Reza's results in terms of field vs. focal length, and also consistent with Haipeng's results in terms of field vs. input power for the most part. We believe the RF system is well-understood, so I believe the only thing that might cause the results to deviate from our simulations is of a more complex particle-kinematical nature, i.e. something to do with space charge. I do not expect such issues to cause a power deviation by a large factor, so my current assumption is that the whole confusion is a result of miscommunication and inconsistent documentation. We shall wait and see.
  Next two weeks (May 10 - May 21)
     - IPAC poster + video + paper done
     - I repeated some simulations of the emittance growth in the IMP experiment with phase dithering to make sure they all use the same, most recent tracking code. Unfortunately, the result does not agree with reality anymore! This may be something to study at a later point. For now, I left the dithering results out of the IPAC material.
     - We wanted to start beam commissioning of the CEBAF injector upgrade this week, but it was delayed by a series of unfortunate circumstances.

   Previous two weeks (Apr 26 - May 10)
     - Continued work with the Brown-Servranckx transform for round, uncoupled beam from a magnetized beam. This requires some non-conservative process in between the magnetized beam transform and the Brown-Servranckx 
       transform - currently investigating the possibility of using space charge to facilitate this. Looking into the space charge modules in PyORBIT for applicability. Dimensionality of the space charge solver greatly 
       affects the tracked beam sizes - working to understand the proper way to utilize the different space charge solver routines. 
     - Laser particle counter: relocated test apparatus to TL 1011, but still need to work with the Detector group to reassemble the components. Vendor has experienced some shipping delays of hardware components and wants 
       to complete some internal testing before bringing the 12-channel prototype on site - tentatively rescheduled the vendor site visit for the week of May 10. Also working to get a PC dedicated to the particle counter experiments.
     - Meeting with Omnisensing Photonics to discuss software development progress.
     - Usual biweekly meeting with Omnisensing Photonics to discuss general progress.
     - Review of student applications as part of the selection committee for MFURA awards.
   Next two weeks (May 10 - May 21)
     - Review of student applications as part of the selection committee for MFURA awards.
     - Continued work with the Brown-Servranckx transform for round, uncoupled beam from a magnetized beam. Trying to characterize the effects of different forms of the Brown-Servranckx transform, both with and without the 2.5D space 
       charge solver enabled. The 3D space charge solver seems to result in huge, unphysical beams, so still trying to understand this module and its implementation
     - Laser particle counter: test apparatus has been reassembled in TL 1011. Minor modifications, including moving the vacuum pump off of the bench to the floor, may be necessary as testing resumes. The vendor has received and tested 
       initial hardware components and plans to be on site 5/26 and 5/27, returning once per week on a continuing basis thereafter.
     - Usual biweekly meeting with Omnisensing Photonics to discuss general progress.
     - Prepared and gave a short presentation on parametric-resonance ionization cooling (PIC and Skew PIC) concepts, implementation, and challenges as part of the 1st Muon Community Meeting hosted by CERN. Presentation was part of an 
       overall presentation on advanced muon cooling concepts.

Andrew Hutton 

   Previous two weeks (Apr 26 - May 7) 
     - Vacation: April 10 - April 17
     - Isotopes: The Quarterly Report has been written and is being submitted today.  We are still trying to understand the data from the irradiations.  Our best guess at the moment is that FLUKA 2020, 
       which now calculates Copper67 production correctly, underestimates the production of Gallium67.  Since we calculate the amount of Copper67 from the ratio derived from the calibration, the crucible experimental 
       data is a factor of ~2 greater than FLUKA.  We are continuing to investigate.  I already wrote to you about the new FOA; this was discussed at the Isotope Meeting and our UVA collaborators are on board to take the lead.             
     - ERL Roadmap: The first draft of the report is due mid may, so things are heating up.  I have started on my sections, but have a lot more to do.     
     - PERLE: Rumor has it that we are really close.  JLab has accepted the latest CNRS edits and the ICRADA has been sent to the DOE for concurrence.  In a video conference with Achille Stocchi, Director of IJCLab, and Jean-Luc Biarrotte, CNRS Directorate, Jean-Luc stated that CNRS are ready to sign this version.  So maybe we are getting there!    
     - HiPERLAC: new name, the pre-Proposal has been uploaded to the Division site and emailed to Leigh.  I have not heard back from BWXT (they have just been named as one of two proposals for micro-reactors for DOE funding and are preparing their next steps) and Framatome (it has been passed to their technical experts). 
     - VCU Engineering Department of Mechanical and Nuclear Engineering: the Industrial Advisory Board met this week.  the focus was on changing the course offerings to attract more people to the Department.  They have been losing out to computer engineering, including cyber security.  They wanted the advice of the local industries as to which courses would be best adapted for hiring, so I was not much use.  
     - VNACA: Also met this week.  There was presentation by a policy wonk as to the impact of all of the new initiatives, including the Infrastructure Bill, and the various climate initiatives.  Nuclear seems to be well integrated into this as it is now generally seen as a green energy source.  Hopefully, this will positively impact approval of HIPERLAC!            
   Next two weeks (May 10 - May 21)  
     - Isotopes: Not much is happening, waiting for results from the irradiations.  I did review Lila’s paper and presentation for IPAC.  There was also a useful meeting with Thia, Drew, and our new collaborators to discuss options for IP protection and using PAN’s small business to go after SBIR money.     
     - ERL Roadmap: This has taken up a lot of time.  I interacted with the section authors to aim the input in the right direction and I am also writing sections.  There will be a symposium on ERLs on June 4, where I have a 25’ presentation on ERL Facilities, which I have to prepare.  I was asked to Chair a sub-Panel on  ERLs for High Energy e+e- colliders.  The sub-Panel members have already been invited, and most have accepted (Reinhard Brinkman, Oliver Brüning, Sergei Nagaitsev, Max Klein, Peter Williams and Frank Zimmermann so far).  The two projects are an ERL FCC-ee which will be presented by Vladimir Litvinenko, and an ERL ILC which will be presented by Valery Telnov.  Both have been contacted and agreed to be reviewed (that was not obvious!).  The sub-Panel will start up in June after the ERL Symposium.       
     - PERLE: Still no ICRADA!   
     - HiPERLAC: I prepared a draft of the full proposal, sent it around for corrections and sent it to Andrei and Mike so they can look at it.  Kelly has the budget info.  Compared to the preliminary proposal, i have added a student from VCU next summer and a software package.  The student will be co-supervised by Prof Supathorn Phongikaroon (Supy) without cost.  I had some back and forth with leigh and this was deemed OK.  Supy will be part of the team next year when we start to lock down the target area.
