摘要：
The features of the vacuum system of the accelerator/storage ring CRYRING are described. Using NEG-pumps based on the St 707 getter developed by SAES Getters (Milan, Italy) of low temperature type activated at 300-degrees-C and operating at room temperature in combination with sputter ion-pumps, a pressure in the low 10(-11) mbar (N2 eqv) region has been achieved without any bake-out of the vacuum system. The design value, 5 x 10(12) mbar (N2 eqv), is expected to be reached after a complete bake out of the system at 300-degrees-C.
