Technical Progress to Date (1) - Lattice • Charge #1 Beam Transfer line to the Booster (BTL) Ø The lattice was redesigned due to the Booster construction strategy changed, and the constrains to avoid the interference between the BTL and the Booster ring. The lattice now is finalized • Beam absorber line (BAL) Ø Switch magnet- Septum for the BAL is placed 2 cells upstream. Another pair of switch magnet Septum is going to be placed in the last 2 straight section cells for the future Mu 2 e line. • • Provided the acceptable tolerances of the magnet and power supplies, based on the simulations of magnetic field errors and misalignments Examined the apertures, especially for the special magnets such as Fast corrector (Switch magnet), Larger aperture quads and Septum in the beam line. • Generated the survey files for CAD 3 D model. • Preliminary designs review completed on December 12, 2019 (PIP-II-doc-4318. ) 10 12/31/2021 M.

Cost Performance Report Charge #3, 6 121. 05. 02 Acc. U – Beam Transfer Line and Beam Absorber • • BAC = $6, 413, 179 CPI=0. 84; SPI=0. 82 • Effort to redesign the lattice of the BTL was not expected. – – – 18 Construction strategy changed. The concern is about the impact to the Booster Enclosure. A solution of a Chute- a beam pipe will be utilized in the current design for the connection between the BTL and the Booster Making the lattice simpler by eliminate the rolls of the dipoles in the line. The concern is so many dipoles are rolled, it would bring the complexity of the magnet installation, and also the risk of the beam commissioning. The lattice is flat and optimized in the current design The lattice now is finalized 12/31/2021 M. Xiao | 121. 05. 02 BTLBA | PIP-II DOE CD-2/3 a IPR - SC 2 - BTLBA
