1 Dust Accelerator: Review of Plan 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 high bay

3 Nuclear Physics Laboratory Status Office Space Repainted 12 offices + lab/sample-prep areas Students presently working at NPL Two electronics labs set up so far High Bay Power installed (Pelletron, pumps, lamps, etc.) Compressed air installed (incl. compressor) Water lines installed (no chiller yet) All work so far from Facilities Management (not CCLDAS project budget)

4 Nuclear Physics Laboratory Status Crane New CU effort to bring campus to OSHA standards $150k from Provost funds to refurbish NPL crane Electrical power & Mechanical / bearings Soft start/stop Remote control Remaining NPL items (near term) Rework last few offices Set up videoconferencing system in library Finish data lines to high bay Water chiller Minor electrical work

5 Pelletron Bid Status University RFP process nearing completion One bid received [National Electrostatics / Pelletron] Lead-time is now 16 months!

6 Accelerator Beamline

7 Beamline Mechanical Structure

8 Subcomponents Underway Detector mechanical fab. CU Physics shop Dust-head mechanical fab. CU Physics shop Detector circuitry Evan Thomas (thanks to Gunter Matt) Beamline mechanical fab. Spencer Leblanc PSU logic Tyler Wingfield Pulser & HV electronics Mike Wagner & Anthony Shu Fiber-optic readout/control M. Wagner & A. Shu SimIon / focusing electrode Matt Zemel

9 Small (20 kV) Accelerator Designed in parallel with large beamline Components being ordered now Electronics built in parallel with large accelerator versions Should be complete/operational in Fall

10 Near-term Action Items Get Pelletron order out the door Beamline hardware Once HV unit is ordered, beamline can be constructed NPL facility items from previous slide Bring up small accelerator as quickly as possible
