  The international Muon Ionization Cooling Experiment aims to demonstrate the transverse cooling of a muon beam by ionization in energy absorbers. The final MICE cooling channel configuration has two RF modules, each housing a 201 MHz RF cavity used to compensate the longitudinal energy loss in the absorbers. The assembly of MICE RF Module is being carried out at LBL. In this paper we will report the recent progress on the assembly work.

Lawrence Berkeley National Laboratory (LBNL) has been engaged in an internal laboratory directed research and development project to define a suitable accelerator physics lattice to support the diffraction limited upgrade of the Advanced Light Source*. Diffraction limited lattices require strong focusing elements throughout. Magnetics design is challenging in that the high gradient magnetic structures are required to operate in close proximity. Lattice development requires a coordinated engineering design effort to ensure the lattice design feasibility. We will present a review of the results of our magnet scoping studies as well as conceptual design specifications for the ALS-U lattice dipole, quadrupole, and sextupole magnet systems. Additionally we will present a conceptual design of refined super-bend magnets for the ALS-U lattice including a discussion of their potential impact on beam emittance.
