Abstract
Abstract In a superconducting cavity resonator, the need to separate the input and output coupling lines from the resonator cavity by the use of vacuumtight microwave windows is avoided by instead having the tubular line(s) for coupling electromagnetic energy into and out of the cavity open into the resonator cavity from below the cavity.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
86 words
A superconducting cavity resonator with one or more tubular lines for coupling electromagnetic energy in and out of the resonator with a coolant vessel surrounding said superconducting cavity resonator wherein the invention comprises tubular lines for coupling having a bend prior to opening into said resonator cavity, with said lines opening into said cavity from below and said bend situated in the coolant vessel lower than the lowest point of the resonator cavity and acting as a cooling trap for gas molecules entering through said lines.
Claim 2
Dependent Claim
86 words
A superconducting cavity resonator with one or more tubular lines for coupling electromagnetic energy in and out of the resonator with a coolant vessel surrounding said superconducting cavity resonator wherein the invention comprises tubular lines for coupling having a bend prior to opening into said resonator cavity, with said lines opening into said cavity from below and said bend situated in the coolant vessel lower than the lowest point of the resonator cavity and acting as a cooling trap for gas molecules entering through said lines.
Claim 3
Dependent Claim
21 words
The superconducting cavity resonator of claim 1 wherein said lines open at the bottom of said resonator into said resonator cavity.
Claim 4
Dependent Claim
18 words
The superconducting cavity resonator of claim 1 wherein said lines open into said resonator cavity without vacuumtight separation.
Claim 5
Dependent Claim
65 words
The superconducting cavity resonator of claim 1 and further including one or more pumping lines opening into the resonator from below, said pumping lines having a bend before opening into said cavity, which bend is disposed lower in the coolant vessel than the lowest point of the resonator cavity, to thereby serve as a cooling trap for the gaseous molecules entering through the pumping line.
Claim 6
Dependent Claim
22 words
The superconducting cavity resonator of claim 4 wherein said pumping lines open at the bottom of said resonator into said resonator cavity.
