Accelerator R and D - Y. Zhang
- Continued optimization of detector region optics in the electron collider ring.
- Prepared the presentation and attended EIC collaboration meeting at BNL.
- Miscellaneous: attended CASA group meeting, attended the JLEIC R&D meeting, attended JLEIC parameter coordination meeting.
- Preparation for and participation in the EIC collaboration meeting: talks on polarization dynamics and interaction region design.
- Geometry tagging LDRD: preparation and submission of a project data sheet.
- Planning design and R&D activities.
Activities planned in the upcoming two weeks:
- Preparation of a 45 min talk for the 2017 Accelerator R&D PI Exchange Meeting.
- Preparation of a presentation for the ICFA Mini-Workshop on Dynamic Apertures of Circular Accelerators.
- Preparation and submission of the final report on the 2017 LDRD geometry tagging project.
- Presentation on the beam polarization design at a Wednesday detector meeting.
- Planning collaboration with SLAC and BNL.
- Started preparing draft documentation for JLEIC ion source requirements. Met with Matt Poelker and others to discuss a path forward for the atomic beam polarized ion source SBIR with Muons, Inc. Will likely revise the SBIR proposal to focus on a D- ion source for JLEIC/as a polarimeter in CEBAF.
- Data analysis for Geometry Tagging LDRD: continued generating plots of nuclear thickness and yield as a function of relative rigidity and A of nuclear remnant for detected particles through the ion downstream final focus triplet. Began plotting similar plots for the second data set using density-weighted distance data.
- Attended the EIC Collaboration Meeting at BNL.
- Attended EIC collaboration meeting at BNL, prepared/gave a talk
- Completed a revision of staged cooling scheme
Computational Physics - Y. Roblin
Diagnostic Development - K. Jordan
- Submitted requisition for $371k worth of waveguide for LERF project
- Continued updating wiki
- Waveguide review posted to https://wiki.jlab.org/lerf/index.php/Reviews
- Working to finish Safety Assessment document, update schedule
- Cryomodule shuffle has begun, first is to secure the vacuum on the 3 modules w/clean tent
- This week I finished up the LCLS-II waveguide layout. We had a review that went well. A list of the WG components were made and you generated a purchase requisition.
- A little time was spent on cleaning up Lab 2.
- Had a conservation with Bryce to talk about the upcoming experiment.
- Working on JPos17 contributions plus I am reviewing the antiparallel acceleration mode with Wojtsekhowski. There may be options available to reduce exposure to C100 radiation damage.
- Still trying to begin mass flow conversation, configure SLM expansion proposal for Arc 10, and get a start on characterizing/demonstrating optical resolution experimentally, prior to diagnostic installation. *Plus X-ray direct imaging.
