Purpose Determine if this UV lamp is adequate for experiments to simulate the photoelectron sheath above the lunar surface due to solar exposure.
After 3 hour warm-up emission varies by ± 0.1µA • After 30 minute warm-up emission varies by ± 1µA • At a radial distance of 100mm from the chamber center: P ≈ 9 W λD≈ 4cm ne≈ 8 x 104 cm-3
To Do Next • Trouble shoot: Verify circuit functionality, etc. • Continue lamp calibrationin new DDPL chamber upon • completion of lid modifications • Study photoemission from lunar dust simulant
