I unpackaged all of the items for the Infleqtion Rb Cold PICAS. I couldn't initially figure out how to attach the "DN40CF (2.75" flange) to DN16CF (1.33" flange) adapter with mounting points 2D+ MOT coil assembly (CAAMPA)" to the laser and coil parts. I tried unscrewing what I think are M4 screws (they took an M3 hex driver), but I could only get 1 out and the other 3 spun without loosening anything or changing the height of anything. I belive these screws go into posts and the laser and coil parts pull away from each other. I am meeting with Hannah Manetsch, who assembled a very similar version of this project but with Cesium, this upcoming morning to figure this out.

I also inspected the glass cell with a 1.33" flange that is our Rb source. It looks good.
