Hi all,
We are preparing our site for a new shielded 400, and we're interested in placing it in the neighborhood of a ~25-year-old unshielded Oxford 600. The 5g line of the 400 will be a bit over 3 feet outside of the 5g line of the 600. (5g diameter of the 400 is about 45 inches, and the 600's is about 26 feet).
Concern has been expressed that a quench of the 400, which sometimes happens when charging a new magnet, may induce a quench in the 600. If this 600 quenches, it may not come back to field, eliminating a highly valued research tool that does not belong to our facility.
What is the likelihood that quenching the 400 would induce this 600 to quench? There certainly are facilities that have charged magnets closer to one another than this, but this 600 is old and may be fragile. Has anyone observed such a "domino quench"? I'd appreciate any insights you may have, descriptions of such events, or experiences of quenches in similar circumstances that did not induce neighboring quenches.
Thanks.
- Josh
