Sophia and Kobi installed two gas valves to the chamber, one for gas injection and one for pressure release. We installed tubing on the helium tank, so we now can directly hook the helium up to the vacuum chamber. With the new valves attached pressure leaks a little again, so we need to tighten everything up on them. All that we need to obtain plasma is an electrical system

Today Sophia, Kiana, and Brett installed the electrode, tightened EVERY SINGLE BOLT, and removed the mass spec sensor. We managed to maintain a 5e-10 Torr vacuum with very little (but not zero) loss. (Is it normal to slowly lose some vacuum in a system like this?) In any case, it seems that we're ready for the next steps: power and gas.
