Abstract
We describe the design and construction of a 178 mm (7 in) diameter auger type hydrogen slush generator. A supercritical helium flow loop, which simulates the performance of a helium refrigerator, cools the generator. The coolant temperature varies down to 5 K and the flow varies about the 1.4 L/s (3 cfm) design point. Our computer model of the auger type generator shows that coolant temperature and auger speed have the greatest influence on slush production rate, although coolant flow rate and auger radial clearance are also important. We will evaluate all these effects in our tests of the system.
