Description

In the end calorimeter of the D-zero experiment, uranium and stainless steel plates are assembled into modules which are to be installed into the cryostat as individual units. A single inner module will be surrounded by 16 middle modules, which are surrounded by 16 outer modules. The 16 modules which comprise the middle ring are to be connected at the outer radius by a link, which is pinned to each front plate. The expected forces at each of the 16 connections vary from 1400 Ib to 69,000 lb (Appendix 1). At the inner radius. the forces are known to be ... continued below

Description

In the end calorimeter of the D-zero experiment, uranium and stainless steel plates are assembled into modules which are to be installed into the cryostat as individual units. A single inner module will be surrounded by 16 middle modules, which are surrounded by 16 outer modules. The 16 modules which comprise the middle ring are to be connected at the outer radius by a link, which is pinned to each front plate. The expected forces at each of the 16 connections vary from 1400 Ib to 69,000 lb (Appendix 1). At the inner radius. the forces are known to be compressive; hence, the edges of the front plates will be allowed to bear directly upon one another. Since it is desirable to minimize the volume of material used, an Inconnel connector plate and pins were chosen. Furthermore, it was observed that the forces between the 9 modules of the top half of the ring are all less than 7,700 lb. Accordingly, a connector was designed for the top half of the ring, with the intention that a separate design be performed for the bottom connections. The purpose of the test was to experimentally verify that the connector scheme designed for the top half of the MH ring (end calorimeter) was adequate for the expected structural loads. The test proved that the design was acceptable.
