A perpendicular biased 2nd harmonic cavity is currently being designed and built for the Fermilab Booster. The purpose is to flatten the bucket at injection and thus change the longitudinal beam distribution to decrease space charge effects. It can also help with transition crossing. A model cavity has been built to verify various CST Microwave studio and COMSOL results and a test stand has been built to ensure that the Y567 tube is able to operate at twice the Booster fundamental frequencies. Also discussed are the RF windows which are critical to the design.

The flagship of Fermilab's long term research program is the Deep Underground Neutrino Experiment (DUNE), located Sanford Underground Research Facility (SURF) in Lead, South Dakota, which will study neutrino oscillations with a baseline of 1300 km. The neutrinos will be produced in the Long Baseline Neutrino Facility (LBNF), a proposed new beam line from Fermilab's Main Injector. The physics goals of the DUNE require a proton beam with a power of roughly 2.5 MW at 120 GeV, which is roughly five times the current maximum power. This poster outlines the staged plan to achieve the required power over the next 15 years.

The Integrable Optics Test Accelerator (IOTA) is an experimental synchrotron being built at Fermilab to test the concept of non-linear "integrable optics". These optics are based on a lattice including non-linear elements that satisfies particular conditions on the Hamiltonian. The resulting particle motion is predicted to be stable but without a unique tune. The system is therefore insensitive to resonant instabilities and can in principle store very intense beams, with space charge tune shifts larger than those which are possible in conventional linear synchrotrons. The ring will initially be commissioned with electrons, but this poster describes progress toward the injection of protons into the ring, using the RFQ originally built for the High Energy Neutrino Source (HINS) project.
