Botany Reaction Chamber

Friday, April 26th, 2013

This is a reaction chamber built for a lab in the UW-Madison Botany department. An acidic aqueous solution will be drawn into the chamber, interacting with two slivers of pyrite (a.k.a. “fools gold”) that are touching each other. The experiment will be monitored through the glass cover, eventually using infrared imaging.

Carting in the Upgrades

Wednesday, April 17th, 2013

Part of the upgrades for CMS includes adding new Cathode Strip Muon chambers. PSL designed and fabricated two carts for transporting six chambers from the factory in Prévessin, France to the LHC .5 Facility. The .5 Facility is the building above CMS, where all equipment is staged to be lowered down 100 meters (328 ft.) to the CMS hall. The chambers are installed onto the CMS endcap disks, then the carts are returned to Prévessin for more chambers.

HSX Little Black Box

Friday, April 5th, 2013

This little black box is a mount for four optical systems on the Helically Symmetric eXperiment (or HSX) at UW-Madison. HSX is a research plasma containment experiment that PSL has been involved with since 1993.

Simon Anderson, from HSX, contacted PSL about building the mount. He sent measurements to PSL, which engineer Ken Kriesel turned into a SolidWorks drawing. Working with PSL designer Amy Pagac, and consulting with Simon, a finished drawing and blueprint were made. Once the print was approved, PSL instrument maker Bart Dana loaded the whole drawing into his CNC mill. From the pictures, you can see there are a lot of pockets for screw heads, seals, and flanges. Something that is not apparent is two of the holes are slightly offset to allow clearance for the mount flanges. All of this was run as a single program.

PSL also modified four commercially available circular adapters to allow the close spacings shown.

Once completed, the mount was black anodized.
