Description
The U.S. Department of Energy is seeking proposals for the production of Forward Hadronic Calorimeter Absorber Structures. The structures will be made of AISI 1020 steel alloy and will require magnetic permeability testing, although the results will be for informational purposes only. The proposal should address all requirements and exceptions, including concerns about laser-beam welding and the use of electron-beam welding. The decision about nickel-plating will be made at the time of vendor selection, and it will be based on the proposal details, cost, period of shipping, and potential exposure until final detector assembly at ORNL.
* The production will require the use of laser-beam welding, which should be sufficient for the materials and dimensions of the module assemblies.
* The proposal should include concerns about laser-beam welding and the use of electron-beam welding.
* The decision about nickel-plating will be made at the time of vendor selection.
* The production will require the use of desiccant packs to maintain protection from corrosion.
* The proposal should include all requirements and exceptions, clearly documented and explained.
