Like a new phoenix, the 40m PSL is in the process of being reborn...

We cleared many old optics and components (including Alberto's favorite periscope) off of the north end of the PSL table.  Some optics are stored on the SP table, others on the shelf inside the PSL enclosure.

The new Innolight 2W NPRO is on the table, the PMC has been moved, and the main path of the laser has been sketched out using steering mirrors. Since we still don't have a beam, we're roughly placing all of our optics, and we'll finalize the alignment after turning on the laser.

Using a leveled HeNe, I checked the height of optics we should use to match the height of optics in the chambers by shining the light at the first steering mirror in the chamber, and ensuring that the beam hit the center of that optic .  Since the new PSL table height is identical to the AP table, it's not a surprise that from now on we will be using a 4" beam height on the PSL table, rather than the old PSL 3" beam height.

On the to-do list is to make a plate with 4 through holes to raise the PMC up by 1 inch, and to make an adapter plate (or come up with another plan) for mounting the AOM that goes directly after the NPRO/Faraday, among many other things.  We also still need to make some space for the RefCav to be put in its new place on the table, and then install it with Steve's help.
