There are currently 5 full cylinders of pre-mix gas in the EEL gas cage. The last order of 4 cylinders arrived last month. These cylinders were for testing the actual detector in the EEL.

I can order more cylinders for delivery to 96B, if that is what you need. There is a 4-6 week lead time for delivery of this pre-mix gas. Does your estimate of 4 cylinders for the run take into acccount any contingency? Additional gas may be required in the
case of an accidental loss of gas for some reason such as a leak or an improper gas supply configuration. I would recommend ordering at least 6 cylinders if you estimate the need at 4, with a contingency of at least 2 cylinders just in case. The lead time
of 4-6 weeks eliminates the option of ordering more during the run. <br>

in principle, the 4 bottles of He/CO2 were in the list to buy them soon, and I believe they are already ordered because the delivery time was quite long. He4 not quite sure if was intended to buy it exclusively for BONuS or use the present in the hall.

<div class="">Hi Sebastian,<br class="">
<br class="">
Based on the Bonus flow requirement of 1 gas exchange per hour, the experiment will need 4 bottles of He4/CO2 (K bottles, 2000 psi). The experiment will also need 1 bottle of He4.<br class="">
<br class="">
Has this gas been ordered?<br class="">
<br class="">
Thanks,<br class="">
