- H 0 H 8 + corrector ORBUMP foil H ABSORBER Gradient Magnet ORBUMP - ORBUMP detector H ORBUMP Charge #2 Preliminary Design and Design Maturity • The Booster injection girder design has been refined to better specify the required component parameters. Gradient Magnet Key features: Ø Absorber moved away from aperture Ø Opened up ORBUMP aperture Ø Reduce GM length by ~0. 75 (to be further optimized) Ø Dedicated phase space painting outside injection straight (Vertical modeled, Horizontal suggested in CDR, yet to be revised) Ø Painting design complete (will re-validate) (CDR) Ø Foil heating checked, not an issue Ø Lattice distortion negligible 1/22/2022

Charge #1 Progress to date (Booster Injection) • Started monthly meeting with AD & TD for design of • Girder - developed initial “envelope” 3 D layout (next slide) – Will update the model and more information becomes available • Painting magnets & PS - No effort to date – Task to start May 2020 • ORBUMP & PS– started evaluating 2 D magnetic design to meet specifications – Effort for PS starts after once U, L, I, C are understood – PDR scheduled for both scheduled April 2019 • Reduced length “D” combined function magnets – preliminary specifications determined –No official activity at present. – Effort to start Spring 2020 after ORBUMP finalized – Injection Absorber – initial MARS simulation on previous design (very similar to current but closer to aperture. Needs optimization) – Foil changer – No explicit activity to date – considering FNAL or SNS design or maybe hybrid 10 1/22/2022

Charge #1 Progress to date 20 Hz Operation • Gradient Magnet Power Supply System – Low power loss measurements and simulations to compare 15 Hz to 20 Hz operation • Discussed last IPR • Documented in Beams doc-4777 -v 1 • No additional effort since then – Configure a complete girder with magnets, resonant components, and power supply • to verify operation at Operational conditions • confirm loss measurements • Validate SPICE model • Use to test the operation of the new reduced length “D” CFM. – No explicit Project activity on this front was planned in FY 18 • Booster power supplies (kicker/septa) – – 13 Kickers ready for 20 Hz Septa (magnet & supply) Detailed modification plans to be developed No explicit activity was planned in FY 18 1/22/2022

Charge #6 ESH • The main motivation in the current design is the reduction of accelerator component activation and minimization of personnel exposure during access periods (ALARA). – The waste beam absorber moved far from the circulating aperture. • Typically, the hottest regions in circular accelerators are the injection, collimation, and extraction regions. – New Injection Insert - we will incorporate design features to minimize exposure during maintenance periods through judicious use of • Shielding • Quick disconnects 14 1/22/2022

Charge #6 Quality Management • All major components used in the upgrade will be Fermilab designed and fabricated either in TD or AD. – Both divisions are committed to Quality Control and have standard operating procedures (SOP) of • • Incoming inspections Acceptance testing (where appropriate) Travelers Final testing to verify performance – Prior to commencement of fabrication • Final Design review • Production Readiness Review – The proposed magnet and power supply designs are not too different from what Fermilab has produced in the past. With each new design lessons learned are incorporated in all phases of design and manufacturing. 15 1/22/2022

Charge #1 Progress to date (20 Hz Operation) Booster Gradient Resonant Magnet 20 Hz Testing • Measurements were performed on both a Booster gradient magnet and a Booster choke with the intent to compare the 15 Hz losses with the 20 Hz losses for a proposed Booster upgrade. No activity since Last year A complete girder measurement still needs to be done to confirm numbers. 18 1/22/2022
