You are designing an ion thruster discharge chamber (operating with xenon) that will have nominal operating conditions corresponding to an internal pressure of 104 torr
You are designing an ion thruster discharge chamber (operating with xenon) that will have nominal operating conditions corresponding to an internal pressure of 104 torr , a plasma density of 2.1097 m, neutral gas and ion temperatures of 500 K, and an electron temperature of 4 eV. As part of your design, you are investigating the effect of (transverse) magnetic field strength on the ion confinement in the discharge. Calculate and plot the confinement factor f. for a magnetic field of 0 to 40 G adjacent to the anode. For these conditions, you can assume a magnetic diffusion length l = 2 cm. In your submission, clearly write out the equations and solution steps for the case corresponding to 40 G along with a printout of the plot. In your solution to this 40 G case, clearly show your results for the following parameters: a) neutral density b) electron-neutral collision frequency c) electron-ion collision frequency d) electron mobility e) Bohm velocity f) transverse ion velocity g) confinement factor Notes: Be careful with units, and remember that 104 G=1T. Submit a copy of the Excel sheet or MATLAB script you prepare to solve the problem.
