“…In a muon collider the Higgs boson can be produced as an s-channel resonance and then the total width can be measured directly with an energy scan across the resonance 183,184 provided that the energy spread of the muon beams is of the same order. Furthermore, this machine would ensure a precise measurement of the Yukawa coupling to muons.…”

The discovery of the Higgs boson has been one the most important results in the whole story of particle physics. A review of the aspects of the long path, starting from the speculative introduction of the Brout-Englert-Higgs mechanism, continuing with the long search to detect the Higgs particle, and arriving to the discovery is given. The first measurements of the properties are described, their implications are discussed and the future prospects are given.

RF cavities are essential components of almost every particle accelerator. Among other limitations, cavity gradients are restricted by occasional sparking inside the cavity, or RF breakdown. It has been shown that presence of external static magnetic field aggravates the influence of breakdown on performance of the cavity. This problem can arise in designs of muon ionization cooling channel, RF guns, klystrons and other applications. The MTA area at Fermilab is the facility that allows us to study the effects of static magnetic fields up to several Tesla on RF cavity operation. As a part of this research program, we have tested "modular" cavity in strong external magnetic fields. The special design of the cavity allowed for easier inspection of the cavity, swapping endplates with different materials and hence better control over sources of systematic errors. Results of high-power tests of "modular" cavity with and without external multi-Tesla magnetic field will be presented.

“…For the muon collider we require a reduction of the normalized x and y transverse emittances by almost three orders of magnitude (from =15,000 to 40 mm mr), and a reduction of the normalized longitudinal emittance by one order of magnitude [26]. This cooling is obtained in a series of cooling sections.…”
