The diameter must be no smaller than 7 mm, and no greater than 15 mm. Overall length is presumably not a problem if we can cut a long spring to size. It is critical, however, that we choose the spring constant appropriately: too small and we get bad thermal contact, but too large and we risk damaging the apparatus or breaking the control string."},"comment":{"url":"https://api.github.com/repos/stanford-physics108-2015/cryo/issues/comments/74409335","html_url":"https://github.com/stanford-physics108-2015/cryo/issues/16#issuecomment-74409335","issue_url":"https://api.github.com/repos/stanford-physics108-2015/cryo/issues/16","id":74409335,"user":{"login":"zmwangx","id":4149852,"avatar_url":"https://avatars.githubusercontent.com/u/4149852?v=3","gravatar_id":"","url":"https://api.github.com/users/zmwangx","html_url":"https://github.com/zmwangx","followers_url":"https://api.github.com/users/zmwangx/followers","following_url":"https://api.github.com/users/zmwangx/following{/other_user}","gists_url":"https://api.github.com/users/zmwangx/gists{/gist_id}","starred_url":"https://api.github.com/users/zmwangx/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/zmwangx/subscriptions","organizations_url":"https://api.github.com/users/zmwangx/orgs","repos_url":"https://api.github.com/users/zmwangx/repos","events_url":"https://api.github.com/users/zmwangx/events{/privacy}","received_events_url":"https://api.github.com/users/zmwangx/received_events","type":"User","site_admin":false},"created_at":"2015-02-15T08:53:27Z","updated_at":"2015-02-15T08:53:27Z","body":"We've discarded the idea of using a spring."}}
