Two have slow nitrogen purges to maintain low relative humidity and the large stainless steel container is also ohmically grounded. Devices can be removed from it and moved to the ESD station while the investigator remains grounded. The station is equipped with an ohmically grounded mat and a neutralizing blower. A filtered ESD air gun is used to remove small particulates if necessary. Once a device has been prepared for testing, the researcher can use foot straps and the ohmically ground mats to transport the detector safely to the test station.
Some experiments including high resolution testing require a vibration free environment.
A commercial table-top optical table sits on four soft rubber feet on top of this large mass. The optical table itself, built of composite materials, offers additional vibration isolation. The table is leveled by threaded feet at the bottom. The table surface is stainless steel, magnetic, and there are tapped holes on 1 inch centers for the placement of optical elements.
