A cryogen vessel port arrangement for a magnetic resonance imaging (MRI) system comprising a port 30 for guiding cryogen into a cryogen vessel is described. The port comprises a siphon tube 32, a siphon cone 33, which is in flow connection with the siphon tube, and a pipe 34 with an inlet opening 35 and an outlet opening 36. The inlet opening is configured for connecting it with a coldhead sock and the outlet opening is in flow connection with the port and the siphon cone. The port comprises a port component 40 which comprises a flow channel 44 with a first opening 41 configured for connecting it with a service siphon (53 figure 4), a second opening 42 which is in flow connection with the siphon cone, and a third opening 43 which is in flow connection with the outlet opening 36 of the pipe. Also claimed is a method of operating such a cryogen vessel port and a magnetic resonance imaging system comprising such a vessel port arrangement. |
