11. In practice, RHEED systems are operated under ultra high vacuums . 12. The entire length of a beamline is normally kept under ultra high vacuum conditions. 13. Taken in high vacuum using an electron gun with an energy of 94 eV. 14. Both TDS are examples of NO desorbing from a single crystal in high vacuum . 15. From 1905 to 1908, Volmer studied chemistry at the photochemical reactions in high vacuums . 16. This is especially common for the large glass manifolds used in high vacuum lines. 17. High vacuum systems must be clean and free of organic matter to minimize outgassing.18. The test was conducted in a high vacuum test chamber. 19. This turbine can also be successfully applied to condensing plants operating with high vacuum . 20. This loss process can be alleviated by operating the trap in an ultra high vacuum .
