Harry,
I just got the response back from my researcher as to the material it will be comprised of and expected pressure.
The material most likely will be stainless steel with a vacuum of between 0.01 and 0.1 torr.
Thank you for the help,
Margaret

Subject: Re: [DCHAS-L] Vacuum Chamber questions?
Margaret - what are the proposed materials of construction and what is the proposed pressure in the chamber? Answers to both of these questions are essential before we get to your question.

Greetings all,
I have a researcher who is proposing to build a vacuum chamber in his lab that is an evacuated tube that is 4.5 m in length and approximately 30 cm in diameter. What immediately came to mind is implosion concerns, shielding for the user, room shielding (basement lab)? Should pressure testing of the equipment be required?
If you have worked with this before or something similar, would you be willing to share? Any lessons learned or SOPs that may be helpful?
Thank you,
