[Patrizia Rossi]

Thank you Denny for promptly answer Tyler’s request. The relocation of the N2 banks is very important for the life of the RICH!

Good morning Tyler,

    Two of those four banks have arrived and can be installed when we have an opportunity to spend some time in the Hall. As far as the gas shed relocation goes I have some thoughts on the matter but I would like to get together with Bob and discuss it before I comment.  That being said...stay tuned and I will get back to you, probably next week.

Cheers,

Hello Bob and Denny,

Since the N2 backup banks for RICH are now empty, we've submitted PRs for four additional banks (two to replace the empties, two to keep on hand since the lead time is few weeks).

Once of the things that has come up in discussions among DSG, INFN collaborators, and Dr. Rossi, is what would happen if the backup banks run out and Hall B is inaccessible or the crane and equipment to move the banks are unavailable. In this situation, RICH would eventually go without N2.

To prevent this, the banks could be moved to the Hall B Gas Shed so they can be more accessible. There is already a spare gas line that is not in use that runs from the gas shed to the forward carriage, so it seems the work would be relatively small to relocate the banks.

Are there any other considerations/costs/work needed to relocate the backup banks outside of Hall B?

Best regards,
Tyler
