HP bottles would work, but, at 40 slm, it will empty in <4 hours.
So, the plan is to use 2 dewars in parallel. What is the time line
on this test?<br>

Amanda,
<br>
thank you for your report, I have a couple of comments on the
Nitrogen system.
<br>
- The 8 hours to fill the RICH are calculated assuming a perfectly
sealed detector, which most likely is not. Thus I will say we need
at least 8 hours, but, depending on the gas leak rate, the time
could be much longer. We can only try and see.
<br>
- If the present dewar is not able to provide 40 slm, do we have
an alternative solution, like bottles for example?
<br>
Best regards,
<br>
Marco
