Max Bruker

  Previous (Mar 29 - Apr 9)
     - Some more simulations to get to the bottom of the energy gain puzzle. There have been some interesting ideas but no convincing solution yet.
     - We made a fresh photocathode for the UITF gun to have enough juice for the optics studies that were planned for the remainder of the time before the upcoming shutdown. However, 
       there were mechanical problems during the transfer of the cathode into the gun. Joe ended up succeeding, but after half a day of beam operation, there was an arc in the gun, and 
       it is now making field emission to the point where it cannot be operated. Whether anything meaningful can be done before the shutdown is not clear yet.
     - I had some discussions with Fu Ma about his simulation of the space charge issue in the pulsed cooling experiment. He is using simplified formulas for the field, which may be
       good enough, but he is seeing an emittance increase without applying jitter, which we did not observe in our simulation. The reasons for that are yet to be determined.
  Next (Apr 12 - Apr 23)
     - UITF work depending on the course of action we decide on...
     - Hoping to make some more improvements to JSPEC.

Amy Sy

   Previous two weeks (Mar 29 - Apr 9)
     - Continued literature review on coupled ion beams from magnetized ion sources. Work at FAIR describes using collimation to reduce the transverse emittance of the coupled beam, collimating away over 50% of the beam in a bid to increase
       dimensionless beam brilliance. Working on setting up simulations in TRACK to work through A. Hutton's initial idea of specific beam transforms to recover a round, uncoupled beam.
     - Laser particle counter: Vendor anticipates delivery of 12 channel prototype detector towards the end of April - working to get a lab bench into the reserved space in the Structures Lab in advance of the prototype delivery, and set up 
       the existing test setup in the new space. Wexx particle counter data and manual indicate that the commercial particle counter can measure particles up to about 3.6 um in diameter, which is somewhat useful for calibrating the new detector.
     - Biweekly meeting with Omnisensing Photonics on detector prototype progress and delivery schedule.
   Next two weeks (Apr 12 - Apr 23)
     - Working 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. The TRACK code doesn't appear to accept arbitrary matrix inputs for beamline definition, so is harder to work 
       with for these purposes.
     - Laser particle counter: Vendor now targeting the week of May 3 for delivery of the 12-channel prototype detector. A lab bench has been moved from storage into TL 1011 for setup of the existing test apparatus. Will be on-site on 4/19 to
       observe/assist with reassembly of the test apparatus. Previously considered utilizing a "gene gun" apparatus to launch single particles in calibration tests, but this type of apparatus is not compatible with the size and speed of 
       particulates to be measured with this detector. Looking into modified bead-pull measurements or a stepper motor setup for testing in air.

Andrew Hutton

   Previous two weeks (Mar 29 - Apr 9) 
     - Isotopes: I spent time preparing a talk that Steve will present at the APS April Meeting.  For this, I started to try and lock down our production numbers and had several meetings about it.  It is still not so clear!  I had an 
       excellent talk with Ethan Balkin. our Program Manager, and sent the noted already.  Since the Isotope Program will not have an FOA before this summer (and we don’t know what form it will take) I have started looking into other funding 
       sources. There may be a possibility of seeking SBIR funds, I have feelers out!  Lila will finish up her program on decay modes of all of the isotopes and will publish that at IPAC’21.  She will not have time to complete the other part 
       of the program, the daughter isotopes produced when a 𝛾, n, p,d,or 𝛼 strike the mother. I have changed Loida’s project to complete this part of the program, and then have Lila and Loida publish the final result together. There was an
       excellent article on gallium in Physics Today by Michael Dickey at North Carolina State in Raleigh.  I contacted him and will be talking with him next week.  I think he will be an excellent collaborator if I can talk him into joining us.         
     - ERLs: The panel met and we have assigned writing tasks, most have accepted.  The timeline is to produce a very first draft in May so that there can be an “community meeting" in June to present the rough vision and seek input. This
       has to happen before the CERN SPC on June 22,23 and the CERN Council meeting June 26.  So that will be a fair amount of work over the next couple of months.   
     - PERLE: I contacted Jean-Luc Biarrotte directly, in French, and actually got a response.  Their marked up copy of the ICRADA was delivered, I forwarded it to Rhonda who has contacted me about her comments, and I think it is close to
       going up to the DOE again - I think!           
   Next two weeks (Apr 12 - Apr 23)  
     - Vacation: April 10 - April 17
     - 'Isotopes: There is still a lot of discussion to try and lock down the results o the two irradiations.  This was partially achieved for the APS talk given by Steve, but we are still working on it. The new FOA came out from the DOE
       Isotope program for training https://science.osti.gov/-/media/grants/pdf/foas/2021/DE-FOA-0002508.pdf.  We will discuss how best to respond on Friday.  Lila is getting to the end of her work, with assistance from Todd (thanks).  
     - ERLS: Still working with Max Klein.  No further news on PERLE, apart from an email acknowledging receipt of our marked up copy which is now in the hands of the IN2P3 lawyers (again).    
     - IJCLab: I received an invitation to be on their International Scientific Council.  
     - FCC-ee: I participated in a r review of the Injector and made several comments.  The Review closeout discussion is on Thursday.  I could not resist suggesting that they look at the LHeC electron complex as the injector (this includes the 
       ERL design by Alex).  
     - HiPer/HiPER Linac: I am continuing to follow up with Framatome and BWXT, and will be writing up an LDRD proposal.  Do you prefer High Performance Linac (HiPer) or High Power, Efficiency and Reliability Linac (HiPER)?
