Status/plans for the development of small scale lab. experiments

Present Facility 20  12 

Ongoing Project Mechanisms of lunar dust adhesion to surfaces (collaboration with Ball Aerospace & Tech. Corp.) Substrate (untreated, treated and coated) preparation (Ball Aerospace). Adhesion between JSC-1 simulants with various sizes and substrates in air (Ball Aerospace). Contact charging measurements related to image force (CU’s plasma lab.).

Ongoing Project (Continuing) Dust adhesion in vacuum (CU’s plasma lab). Setup for centrifuge measurement

Ongoing Project (Continuing) Dust adhesion in plasma environment (CU’s plasma lab.).

Near Future Plans A coming UV lamp will be tested and calibrated in the small chamber. Power supply Zr or Pt sheet UV lamp Vacuum pump

Plans (continuing) 42  25  Top part of the chamber

Plans (continuing) Photoelectron sheath will be characterized with a larger chamber and a lamp array assembled as a UV source. UV lamp array Emissive probe Langmuir probe Zr surface UV Lamp Array
