	Abstract' New LCLS-II Linear Superconducting Accelerator Cryomodules under construction at Fermilab. Inside each SCRF Cryomodule installed superconducting magnet package to focus and steer an electron beam. The magnet package has the iron dominated configuration with racetrack type quadrupole and dipole conductively cooled coils. For easier installation the magnet could be split in the vertical plane. Initially the magnet was tested in a liquid helium bath, and were performed high precision magnetic field measurements.

In the paper presented Cryomodule magnet packages test results, discussed the magnet, and current leads conduction cooling performance.

	A perpendicularly biased tuneable 2nd harmonic cavity, designed for the Fermilab Booster, is being assembled for testing this summer (2018). The cavity will work at twice the frequency of the fundamental cavities, and will be on only during the injection and transition (or extraction) periods. The main purpose of adding this cavity is to improve beam capture and reduce losses as required by Fermilab's Proton Improvement Plan (PIP). After three years of testing and optimization, the cavity design has now been finalized and all constituent parts have been received. We report on the cavity final design and on the status of the construction.

A perpendicularly biased tuneable 2nd harmonic cavity, designed for the Fermilab Booster, is being assembled for testing this summer (2018). The cavity will work at twice the frequency of the fundamental cavities, and will be on only during the injection and transition (or extraction) periods. The main purpose of adding this cavity is to improve beam capture and reduce losses as required by Fermilab's Proton Improvement Plan (PIP). After three years of testing and optimization, the cavity design has now been finalized and all constituent parts have been received.
