TL;DR
This paper details the construction and quality control processes of the 4 K outer cryostat for the CUORE experiment, emphasizing production techniques and validation tests for a low-radioactivity environment.
Contribution
It presents the design, manufacturing, and validation procedures of the CUORE cryostat's outer shell, a critical component for low-background physics experiments.
Findings
Successful production and delivery of the cryostat vessels
Validation tests confirmed compliance with design specifications
Established quality control protocols for cryostat components
Abstract
The external shell of the CUORE cryostat is a large cryogen-free system designed to host the dilution refrigerator and the bolometers of the CUORE experiment in a low radioactivity environment. The three vessels that form the outer shell were produced and delivered to the Gran Sasso underground Laboratories in July 2012. In this paper, we describe the production techniques and the validation tests done at the production site in 2012.
