The feasibility of a next generation neutrino observatory in Europe is being considered within the LAGUNA design study. To accommodate giant neutrino detectors and shield them from cosmic rays, a new very large underground infrastructure is required. Seven potential candidate sites in different parts of Europe and at several distances from CERN are being studied: Boulby (UK), Canfranc (Spain), Fréjus (France/Italy), Pyhäsalmi (Finland), Polkowice-Sieroszowice (Poland), Slanic (Romania) and Umbria (Italy). The design study aims at the comprehensive and coordinated technical assessment of each site, at a coherent cost estimation, and at a prioritization of the sites within the summer 2010.

The Air Force Phillips Laboratory Gyro-BWO experiment i.s utilizing the RAMBO pulser, with electron beam parameters of V, = 300-800 kV; I,=1-50 kA, pulselength = 1-3 ps.An annular electron beam of -1-3 kA is produced by an annular aluminum cathode. The interaction cavity ii designed to radiate in the frequency range of 4.2 -5.5 GHa

The Superconducting Super Collider (SSC) LINAC Injector consists of an Ion Source, Low Energy Beam Transport (LEBT) and Radio Frequency Quadrupole accelerator source LEBT R FQ (RFQ). The LINAC Injector is required to provide 25 mA of H-beam (pulse width of 9.6-48 ps at 10 Hz repetition rate) at 2.5 MeV with transverse normalized rms emittance (Et-n-ms) of less than 0.2 K mm-mrad and longitudinal normalized rms emittance (&I) of less than 0.82*10-6 eV-s. An RF-driven volume source was chosen for the initial commissioning of ,on Extractor the SSC LINAC Injector. The RF volume source generates beams with Et-n-rms as low as 0.06 K mm-mrad while Figure Functional diagram of ssc LINAC meeting all other SSC ion source operating requirements (30 mA at 35 keV). The highly converging input beam required by the SSC RFQ is provided by a dual einzel lens.The initial experimental results from commissioning of the SSC LINAC Injector and experimental results pertinent to the performance of the SSC ion source and LERT will be discussed.
