An extremely thin superconducting solenoid magnet is being developed to investigate cosmic-ray antiparticles in the Universe. The uniform solenoidal field is provided in a particle detector system to ...analyze the particle momentum. The solenoid coil is wound with advanced aluminum stabilized superconductor recently developed by using micro-alloying with Ni, followed by cold-work mechanical hardening. It is designed with a central magnetic field of 1.2 T in a volume of 0.9 m in diameter and 1.4 m in length. The radiation thickness of the coil is to be 0.056 X/sub 0/ with a physical coil thickness of 3.4 mm. This paper describes the conceptual design and progress of basic development work.
Carbon dioxide absorption rates into water were measured to determine volumetric mass transfer coefficients, kLa, in bubble and slug flow regimes of gas-liquid two-phase upflow through a 0.030m i.d. ...vertical tube. Axial local values of kLa decreased rapidly downstream from gas inlet. Axial averaged values of kLa, which is denoted by (kLa)z, were affected by gas velocity, uGO and distance from gas inlet, z, being correlated by the following equations: (kLa)z=0.81uGO1.20Z-0.62
