- Rails
- Currently in transportainer at IU, George will have a look when he goes out there.
- Cryo can and heat exchanger
- RFQ out for cryo can, no delivery date yet.
- Heat exchanger from Hall A.
- Piping
- Not clear where N2 vent will be routed.
- Must incorporate drip pan under N2 vent due to icing.
- May be ODH considerations.
