1 NLSI All-Hands Meeting
August 2009 Andrew Poppe LASP / CU

2 Simulation Description
1-D Particle-in-cell simulations ran with only photoelectrons Photoelectrons emitted from left boundary with specified velocity distribution Grard & Tunaley, 1971, derive analytic expressions for three velocity distributions, two of which are shown here Rectangular Maxwellian Comparison of the simulated and theoretical electron density in the sheath

3 Theoretical Comparison - Rectangular

4 Theoretical Comparison - Maxwellian

5 Photoelectron Velocity Distributions
Measured photoelectron distribution of lunar fines can be used in the simulation to compare to standard cases [Feuebacher et al., 1972]

6 Comparison of electron density profile

7 Comparison of electric field profile
