Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
68 words
A compton spectrometer comprising semiconductor detectors including a primary semiconductor detector for intercepting primary radiation and a secondary semiconductor detector for secondary or scattered radiation, wherein the improvement comprises, said detector for the primary radiation being a semiconductor made of a material having a low atomic number and said detector for the secondary or scattered radiation being a semiconductor made of a material having a high atomic number.
Claim 2
Dependent Claim
68 words
A compton spectrometer comprising semiconductor detectors including a primary semiconductor detector for intercepting primary radiation and a secondary semiconductor detector for secondary or scattered radiation, wherein the improvement comprises, said detector for the primary radiation being a semiconductor made of a material having a low atomic number and said detector for the secondary or scattered radiation being a semiconductor made of a material having a high atomic number.
Claim 3
Dependent Claim
59 words
A compton spectrometer comprising semiconductor detectors including a primary semiconductor detector for intercepting the primary radiation and a secondary semiconductor detector for secondary or scattered radiation, wherein the improvement comprises, material of the semiconductor detectors being drifted and said detector for the primary radiation being a Si(Li)-detector and the detector for the secondary or scattered radiation being a Ge(Li)-detector.
Claim 4
Dependent Claim
59 words
A compton spectrometer comprising semiconductor detectors including a primary semiconductor detector for intercepting the primary radiation and a secondary semiconductor detector for secondary or scattered radiation, wherein the improvement comprises, material of the semiconductor detectors being drifted and said detector for the primary radiation being a Si(Li)-detector and the detector for the secondary or scattered radiation being a Ge(Li)-detector.
Claim 5
Dependent Claim
54 words
The compton spectrometer, as set forth in claim 1, wherein said first and second detectors are arranged with means for using the sum of the energies of the radiations detected by said two detectors for energy analysis of one radiation passing successively through both detectors in order to cancel disturbing effects of line broadening.
