The National Superconducting Cyclotron Laboratory at Michigan State University is a Radioactive Ion Beam (RIB) facility providing beams of exotic nuclear species through projectile fragmentation. The Coupled Cyclotron Facility accelerates stable ion beams to ~100 MeV/A which are then fragmented and selected with the A1900 separator. A recent addition to NSCL is the gas stopping facility which thermalizes the high energy beam. The RIBs are extracted at <60keV and selected by A/Q for further transport to the low energy areas, currently consisting of the BECOLA beam cooling and laser spectroscopy system, and LEBIT Penning trap. RIBs up to 6 MeV/A will be provided by the ReA post-accelerator, currently consisting of an EBIT, RFQ and superconducting RF cavities. Energies up to 1.5 MeV/A are presently available, and energy increases will be phased in with the addition of further cryomodules. In a campaign of commissioning experiments, RIBs from a fragmentation facility were thermalized and post-accelerated for the first time. Preliminary results will be presented, focussing on the diagnostic challenges of detecting and characterizing beams over a wide range of energy and rate.

Within LA3NET, Laser Applications for Accelerators are being developed by an international NETwork of more than 30 partner institutions from across the world. Laser-based beam instrumentation is at the core of this EU-funded project which will train 17 fellows during its four year project duration. In this contribution, we will present the consortium's recent research results in beam diagnostics, ranging from development of a laser velocimeter and laser emittance meter, over measurement of the bunch shape with electro-optical sampling in an electron accelerator and precision determination of electron beam energy with Compton backscattered laser photons to measurement of electron bunches with a time resolution of better than 20 femtoseconds. We will also provide a summary of past training events organized by the consortium and give an overview of future workshops, conferences and schools.
