Accelerator R and D - Y. Zhang
Fanglei Lin

• 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.

Vasiliy Morozov

• 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.

Amy Sy

• 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.

Yuhong Zhang

• Attended EIC collaboration meeting at BNL, prepared/gave a talk
• Completed a revision of staged cooling scheme

Diagnostic Development - K. Jordan
Kevin 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

Joe Gubeli

• 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.

Mike Tiefenback

• 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.
