THE VACUUM SUITCASE TRANSFER Transcript
This is a demonstration of a vacuum artifact transport system that we have developed at NIST. A sensitive, delicate gallium arsenide semi-conductor specimen that's making, or has just begun its journey, from a UHV (ultra-high vacuum) system on my right, to another system, a molecular beam epitaxy system over in the Technology Building about 400 yards away. The sample sits inside this chamber here in ultra-high vacuum, approximately 10 to the -7 pascal, and we will be rolling it out the door, down the hall, and into an adjoining hall to make its journey over to the Technology Building where the molecular beam epitaxy system is, and where our colleagues in the Electronics and Electrical Engineering Laboratory are waiting. Riding on this cart, which supports the vacuum system, also is a special data logging system that we have developed to monitor any accelerations in the motion of our artifact transport system and the vacuum gauges as well. So we will be starting this journey right about now.
We just completed a transfer of a semi-conductor sample from this ultra-high vacuum vacuum suitcase into the molecular beam epitaxy facility within the Electronics and Electrical Engineering Laboratory here at NIST.
The vacuum suitcase has been a joint project between the Manufacturing Engineering Laboratory and the Electronics and Electrical Engineering Laboratory here at NIST for the past five years. We now have the capability to grow semi-conductors in ultra-high vacuum and transfer them in ultra-high vacuum to the UHV scanning tunneling microscope facility within MEL (Manufacturing Engineering Laboratory
