Presentation Transcript

  1. Dust Accelerator: Status and Plans • 3 MeV dust accelerator • Particle sizes: 0.2 – 2.5 m • Particle velocities: < 100 km/s • Large test chamber • UV sources • Solar wind simulator • Various targets • Small (UHV) test chamber • Microphysics diagnostics • Additional 20 kV ‘mini’ accelerator • Prototype dust head, detectors, etc.

  2. Pelletron in NPL • Designed after Heidelberg facility • HV chamber • Dust head • Beam lines • Particle selection units • Located in NPL on East Campus (Physics) • Previous use : CU cyclotron • 90’ x 56’ high bay (shared) • 50 ton crane • Lots of power and shielding • 12 offices + lab/sample-prep areas

  3. Pelletron in NPL high bay

  4. Pelletron in NPL high bay

  5. NPL Second Floor

  6. Near-Term Items • NPL Renovation / Re-inhabitation • Clear / Paint offices • Clear high-bay space • Bring power/water/air to Pelletron area • FacMan supplied $50k of ICR funds for project • Pelletron order • 12-month lead time until delivery • Chamber / vacuum sys. / cooling / beamlines / detectors / PSU / etc. can be completed during interim • Complete fabrication of 20 kV mini-accelerator
