Thomas Jefferson National Accelerator Facility Page 2 UITF Progress meetingOutline Purpose: to inform Lab Leadership of the UITF status Action Items (from previous meetings) Project Update –Progress Update –Milestones Update –Budget Update –Highlights & Concerns –Next meeting agenda

Thomas Jefferson National Accelerator Facility Page 3 UITF Progress meeting To refresh your memory… Today UITF as imagined beamline design and entry/exit need work need to refine rack layout, AC power, add stairs

Thomas Jefferson National Accelerator Facility Page 4 UITF Progress meeting Action Items – From May 13, 2015 Minutes R. Sprouse: confirm the UITF enclosure finish date – Nov 2015 or Feb 2016 M. Logue: consult with Vashek on the shape of the labyrinth (U-shape vs 2 hall). It is felt that 2 bounces are achieved through the current configuration. Done M. Poelker/W. Oren: determine if the 18 FTEs requested to complete the work are prioritized correctly – is a squeeze play possible? Yes: Cryo, Mech Design and SSG M. Poelker: provide a summarized level spreadsheet comparing Areti’s original estimate with the current estimate, noting the differences. Done M. Poelker: request B. May confirm safety tasks associated with the Aug 2016 finish date. We have a list, Hari to work on it M. Poelker/W. Akers: create a detailed schedule with milestones that can be updated during each meeting Pass 1 complete, Detailed schedule In progress M. Poelker: get Vashek’s approval of > 100 nA now. Yes, good plan for 100uA M. Poelker/R. Sprouse: determine disposition of the concrete walls being removed Done L. Wells: setup regular meetings for updates on the project progress – monthly or every 6 weeks All: provide names to attend the update meetings briefing the UITF progress Accelerator: TBD, Engineering: TBD, Physics: TBD, Facilities: R. Yasky, EHS&Q: TBD

Thomas Jefferson National Accelerator Facility Page 12 UITF Progress meeting Today’s layout, ready to cut metal….. Cryo lines hug the wall, waveguides on same side as cryo lines Heat exchanger added to the mix, Rao says this will make things more efficient and stable Design by Shaun Gregory

Thomas Jefferson National Accelerator Facility Page 13 UITF Progress meeting Cryo lines compatible with old and new ¼ CM… Looks similar to our “upgrade injector” front end

Thomas Jefferson National Accelerator Facility Page 14 UITF Progress meeting EHS&Q related tasks (from Bob May) Global hazard review (can be documented in FSAD)  Radiation source term, shielding design, assessment, approval, installation  Final ODH assessment, with Cryo?  Standard industrial hazards (electrical, fall protection, emergency egress, magnetic and RF field exposure, etc.) FSAD update (Rev 8) incorporating hazards assessment and mitigations ASE development and submittal (Rev 8) for TJSO approval Commissioning Plan Development (Internal or External?) Review of Commissioning Plan (CP) Operations plan/procedure development (related to Accelerator Operations Directives? Borrow from and scale down LERF procedures?) Decision about type of ARR and who participates – external/internal/combo Accelerator Readiness Review Plan Review (can be done with CP Review) Work with SSG to implement PSS, RCD to implement CARMS Conduct Hot Checkout (test all installed systems – ready for safe/effective ops) Conduct ARR Obtain TJSO permission to commission UITF (must include shileding effectiveness check, verification of safety device performance Commissioning results report Obtain TJSO permission to operate UITF Hari has agreed to work on this

Thomas Jefferson National Accelerator Facility Page 17 UITF Progress meeting Schedule Ramifications Current status: Close to having a working 350kV gun Nice progress on “stretch” goals: RF, magnets, bpms keV beamline design GOOD, start building it Next month activities (August) Finish mechanical design for gun “Plan Z” Order the keV beamline girder Survey and Alignment: add survey monuments, locate gun, beamline girder and ¼ CM positions MeV beamline design: optics model and mechanical Stairs to top of Cave1, work with FM on next set of projects (HVAC, LCW, new concrete walls Cave2 and braces, control room) Fan and feed: ODH system, cryo lines, trim cards, network, IOCs and software, I&C Dissatisfaction with my “schedule”, improve it, resource-loaded?

Thomas Jefferson National Accelerator Facility Page 18 UITF Progress meeting Schedule Ramifications In two months (September): Start building the keV beamline, ¼ CM moved into Cave anticipating Cryo line installation Electronics racks installed, powered. Start populating racks Add network and controls Apply high voltage to new gun design (our Plan Z) Optics model of MeV beam line complete, mechanical design taking shape Start work on Control Room Move some shield blocks? Build as much of Cave2 perimeter as possible Recall, next big milestone…commission ¼ CM (no beam), scheduled for Jan (cryo, ODH, LL and HP RF, software, adequate shielding, EHS&Q approvals)

Thomas Jefferson National Accelerator Facility Page 25 UITF Progress meeting Issues & Concerns Facilities wrap up by December would be better CTF is not big enough to support three LHe Users. How to “park” the ¼ cryomodule? –UITF (4 to 6 wks, 3 times per year) –CMTF and LCLS II –VTA How long will it take to design MeV beamline? Groups are busy but I continue to be optimistic that work can get done opportunistically within project timeline. Facilities, Mech Design, Cryo, SSG, and Ops software have expressed most reservations

Thomas Jefferson National Accelerator Facility Page 26 UITF Progress meetingSummary There is progress, we are moving forward Progress will become more obvious soon. By October, expect to see some beamline, with ¼ CM inside the cave, electronics racks above the cave…. Hope the Lab can continue funding at ~ FY15 level We are being responsible with money and we are respectful of other JLab work priorities…
