Abstract
A radiation shielding structure includes multiple shielding elements configured to be enclosed within a housing assembly of a camera. The multiple shielding elements include first and second shielding elements. The first shielding element is configured to be placed over a set of cold components of the camera and includes a window opening to pass light. The set of cold components includes a sensor chip assembly (SCA) for detecting the light. The second shielding element is configured to be placed under the SCA and to connect to the first shielding element in order to form a chamber within which the set of cold components is enclosed.
Claims20
A radiation shielding structure comprising:
- multiple shielding elements configured to be enclosed within a housing assembly of a camera, wherein the multiple shielding elements include:
- a first shielding element configured to be placed over a set of cold components of the camera and including a window opening to pass light, the set of cold components including a sensor chip assembly (SCA) for detecting the light;
- and
- a second shielding element configured to be placed under the SCA and to connect to the first shielding element in order to form a chamber within which the set of cold components is enclosed, wherein first shielding element and the second shielding element do not touch the set of cold components.
A camera comprising:
- a housing assembly;
- a set of cold components including a sensor chip assembly (SCA) configured to detect light;
- and
- multiple radiation shielding elements configured to be enclosed within the housing assembly, wherein the multiple radiation shielding elements include:
- a first shielding element configured to be placed over the set of cold components and including a window opening to pass the light;
- and
- a second shielding element configured to be placed under the SCA and to connect to the first shielding element in order to form a chamber within which the set of cold components is enclosed, wherein first shielding element and the second shielding element do not touch the set of cold components.
A method comprising:
- providing multiple shielding elements configured to be enclosed within a housing assembly of a camera, the multiple shielding elements including:
- a first shielding element including a window opening to pass light;
- a second shielding element including a hole for a cold finger to pass through;
- and
- a third shielding element;
- placing a window housing member of the housing assembly over the first shielding element;
- placing the first shielding element over a set of cold components of the camera, the set of cold components including a sensor chip assembly (SCA) for detecting the light;
- placing the third shielding element under the SCA;
- covering the hole of the second shielding element;
- and
- installing the second shielding element under the third shielding element and in connection to the first shielding element to form a chamber within which the set of cold components is enclosed.
