High vacuum vs ultra high vacuum
WebHigh vacuum -103 - 10-7 Ultra high vacuum -10-7– 1012 The different types of vacuum pumps are available for dif- ferent pressure ranges of vacuum. Noramally the manufactu- rere provides the characteristics curve showing relation of pumping speed versus pressure for each vacuum pump. WebFor high voltages (MV) and large distances (cm) in ultra high vacua (10 ~9 to 1CT 8 torr), present investigations at CERN show that, in fact, the mechanism involved in initiating a breakdown takes a considerable time (jis to ms) to develop and that these times are statistically distributed in such a way that T min is proportional to V 2.
