  • Vacuum compatible X-ray shield
    Patent number: 11972920
    Abstract: Methods and apparatus are disclosed for providing an X-ray shield within an ultra-high vacuum enclosure. A shell is fabricated, leak-tested, filled with an X-ray shielding material, and sealed. An elongated twisted X-ray shield can be deployed within a pump-out channel of an electron microscope or similar equipment. The shield can incorporate lead within a stainless steel shell, with optional low-Z cladding outside the shell. Further variations are disclosed.
