TL;DR
This paper evaluates the mechanical properties of LB650 cavities, focusing on heat treatments and transportation impacts, to ensure their structural integrity during handling and shipping in the PIP-II project.
Contribution
It provides experimental data on niobium cavity mechanical properties after heat treatments and establishes transportation and handling guidelines for LB650 cavities.
Findings
900°C heat treatment improves cavity handling and transportation safety
Drop and road tests confirm cavity durability under specified conditions
Guidelines for transportation and shipping container design are proposed
Abstract
The PIP-II project's LB650 cavities could potentially be vulnerable to mechanical deformation because of the geometric shape of the cavity due to reduced beta. The mechanical property of the niobium half-cell was measured following various heat treatments. The 5-cell cavities were tested in a controlled drop test fashion and the real-world road test. The result showed that the 900 C heat treatment was compatible with cavity handling and transportation during production. The test provides the bases of the transportation specification and shipping container design guidelines.
