Hi,
I am new to this list. I have a grant funded to install a 500 MHz NMR (Varian) in a conference room located along a hallway. The NMR will be actively shielded. Varian checked-out the site and gave a blessing on the site; however, there has been considerable concern generated regarding the possibility of a quench and how to ensure that people in the room are safe. The room measures approximately 12' x 20' and has ventillation (temperature stability has not been determined). Our campus safety officer has recommended an oxygen sensor tied to an exhaust fan to exchange the atmosphere in the case of a quench.
I have two major questions:
(1) Have any of you done this and, if so, do you know how much this will cost and who (engineers) could design this system? I have approximately $20 - 40K in my budget for site prep which will need to include an air compressor, installing 200V in the room, and ensuring +/- 1 degree temperature control in the room.
(2) How necessary is such an oxygen sensor tied to an exhaust fan?
Thanks for any help that you can give me.
Phil
