The results of Monte Carlo radiation shielding study performed with the MARS15 code for the final design of the vertical test cryostat facility to be installed in the Industrial Building 1 at Fermilab are presented and discussed.

We outline the design of beam experiments for the electron linac at the Fermilab Accelerator Science and Technology (FAST) facility and for the Integrable Optics Test Accelerator (IOTA), based on synchrotron light emitted by the electrons in bend dipoles, detected with gated microchannel-plate photomultipliers (MCP-PMTs). The system can be used both for beam diagnostics (e.g., beam intensity with full dynamic range, turn-by-turn beam vibrations, etc.) and for scientific experiments, such as the direct observation of the time structure of the radiation emitted by single electrons in a storage ring. The similarity between photon pulses and spectrum at the downstream endmore » of the electron linac and in the IOTA ring allows one to test the apparatus during commissioning of the linac.« less

The conventional manufacturing process for Nb/sub 3/Sn multifilamentary superconducting wire is a combination of hot extrusion and wire drawing. An alternative process, cold hydrostatic extrusion, was developed in our laboratories. All experimental data pertaining to the hydrostatic extrusion process are presented, and a comparison is made between the two manufacturing methods. The results show that monofilamentary Nb/sub 3/Sn wire produced by hydrostatic extrusion not only has good superconducting properties, but also that larger reductions are achieved per pass, and fewer and shorter intermediate anneals are required in its manufacture.
