cleaning cleanroom and particle count

    NOTE: particle counter was found dead, with the charging dock unplugged. For future reference, if you need to unplug the dock, please either plug it back in when you're done, or make a note in an elog so someone else can come down and charge it.

    • zone 4: We were only able to charge the particle counter a small amount before starting the cleaning, so it died again halfway through this measurement, and we didn't get results for zone 4. In interest of time, we just put it on the charger and started the cleaning.
