Abstract
Abstract A resonator is provided for electron spin resonance spectroscopy. The resonator comprises a first wall element which delimits a cavity and which is in releasable contact with other wall element delimiting the cavity. The connection between the first wall element and at least one of the additional wall elements is effected only by spring force (single figure).

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
132 words
A resonator for electron spin resonance spectroscopy, comprising: a cup-shaped element having a cylindrical wall with a bottom at one end thereof and first threads formed on said wall proximate an opposite end thereof; a tube having openings at both ends and being received within said cup-shaped element, said tube being provided with a conductive coating, a first of said openings of said tube adjoining said cup-shaped element bottom; a plate received within said cup-shaped element and adjoining a second of said openings of said tube opposite said cup-shaped element bottom; an insert fitted into said cup-shaped element opposite end and having second threads mating with said first threads; and a spring means arranged between said insert and said plate for urging said plate and said tube against said cup-shaped element bottom.
Claim 2
Dependent Claim
132 words
A resonator for electron spin resonance spectroscopy, comprising: a cup-shaped element having a cylindrical wall with a bottom at one end thereof and first threads formed on said wall proximate an opposite end thereof; a tube having openings at both ends and being received within said cup-shaped element, said tube being provided with a conductive coating, a first of said openings of said tube adjoining said cup-shaped element bottom; a plate received within said cup-shaped element and adjoining a second of said openings of said tube opposite said cup-shaped element bottom; an insert fitted into said cup-shaped element opposite end and having second threads mating with said first threads; and a spring means arranged between said insert and said plate for urging said plate and said tube against said cup-shaped element bottom.
