Abstract

The 20,000 gls. Liquid Argon dewar stores up to 15,000 gls. of high purity (<1.0 ppm O{sub 2}, 0.999995) LAr for use in the Liquid Argon calorimeters of E740, the D0 collider detector, at elevation 707-feet. The dewar provides for the total detector volume of 11,000 gls and a 4,000 gls. storage inventory. The large gas volume ({ge}5,000 gls.) serves operational needs and guards against overfill concerns. The LAr dewar functions in two modes: (1) low pressure (16 psi relief) storage, and liquid and gas transfer operations to and from the low pressure (13 psi relief) detector cryostats, and (2) high pressure (65 psi relief) liquid transfer operations to and from a delivery trailer at elevation 743-feet. The storage function is intended to be long term and nonventing. The dewar is equipped with a 40 kW LN{sub 2} condenser that operates to maintain the pressure constant in the storage mode. This service exactly parallels the NeH{sub 2} and D{sub 2} storage dewar services provided at the 15-feet bubble chamber for its operation.

DO (D Zero) is a large Liquid Argon (LAr) HEP Calorimeter designed to function in the laboratories P-Pbar collider at the DO section of the Tevatron accelerator. It contains 5,000 gls. of LAr in the CC cryostat, and 3,000 gls. in each of two, a north and south, EC cryostats. These low pressure vessels are filled with detector modules built of stainless steel, copper and depleted uranium. The LAr functions as the ionization medium, and the spatial and temporal of the collection of the charge of the electrons produced signals the passsage of charged particles. The collection of these chargesmore »« less

Evaluation of prestressed cast iron pressure vessels for coal gasifier, Appendix A. ASME Code considerations for Section VIII. Final technical report

Not Available March 1979

The large-scale introduction of PCIV for Coal Gasifiers and/or Thermal Energy Storage would eventually require compliance with a safety code. The PCIV is a relatively new technology in which not much attention has been placed on development of an applicable section of the ASME Boiler and Pressure Vessel Code. Presently, there is no ASME code directly applicable to the PCIV concept. Based on this situation, a new draft PCIV code was developed in which parts of Section III, Division 2 and Section VIII, Division 2 were melded into one code. The cast iron design criteria were based on current largemore »« less
