Lots of progress on the PSL buildings. Anteroom and Laser room both have HEPA units running full speed, and garb is now required to enter the Laser room. The airshower to the anteroom has a few issues that need to be worked out, and needs to be hooked into the access control system. Gerbig finished building the Diode room and we have electritians working on wiring environemental sensors and proximity sensors. The chiller room has a hanging chiller in it, but we are waiting on a company to make us the shroud that will go from the chiller to the chimney. Water piping is being worked on, hopefully it will be finished on Thursday.
