Large single grain Gd1.5Ba2Cu3O7-y (Gd1.5) bulk superconductors were fabricated by a top-seeded melt growth (TSMG) process using an NdBa2Cu3O7-y seed. The seeded Gd1.5 powder compacts with a diameter of 50 mm were subjected to the heating cycles of a TSMG process. After the TSMG process, the diameter of the single grain Gd1.5 compact was reduced to 43 mm owing to the volume contraction during the heat treatment. The superconducting transition temperature (Tc) of the top surface of the single grain Gd1.5 sample was as high as 93.5 K. The critical current densities (Jcs) at 77 K and 1T and 1.5 T were in ranges of 25,200-43,900 A/cm2 and 10,000-23,000 A/cm2, respectively. The maximum attractive force at 77 K of the sample field-cooled using an Nd-B-Fe permanent magnet (surface magnetic field of 0. 527 T) was 108.3 N; the maximum repulsive force of the zero field-cooled sample was 262 N. The magnetic flux density of the sample field-cooled at 77 K was 0.311T, which is approximately 85% of the applied magnetic field of 0.375 T. Microstructure investigation showed that many Gd2BaCuO5 (Gd211) particles of a few μm in size, which are flux pinning sites of Gd123, were trapped within the GdBa2Cu3O7-y (Gd123) grain; unreacted Ba3Cu5O8 liquid and Gd211 particles were present near the edge regions of the single grain Gd1.5 bulk compact.

본 연구는 기존 비닐하우스 아연도 강관을 사용한 하우스 폭 3.6m와 5m 천창개폐형 대립계 포도 비가림하우스에 대한 구조적 안전성을 검토하고, 인장강도 400N·mm-2(SGH400 등) 이상의 파이프를 사용하는 조건에서 하우스 폭 5m인 천창개폐형 대립계 포도 비가림하우스에 대하여 구조적으로 안전한 최적 파이프 규격을 제시하고자 수행하였다. 주기둥 3m×서까래 60cm인 천창개폐형 3.6m 비가림하우스의 경우, 적설심 35cm에서는 구조적으로 안전한 것으로 분석되었으나 측면 및 전후면 풍속 35m·s-1에서는 불안전한 것으로 나타났으며, 동일 주기둥과 서까래 간격을 갖는 천창개폐형 5m 비가림하우스의 경우에는 적설심 35와 풍속 35m·s-1에서 모두 불안전하여 구조보강이 필요한 것으로 분석되었다. 그리고 동일 주기둥과 서까래간격을 가지나 인장강도 400N·mm-2 이상을 갖는 파이프를 사용하는 조건에서 천창개폐형 5m 비가림하우스의 최적 파이프 규격은 지붕높이 1.6m(아치형)와 지붕높이 1.8m(복숭아형)에 대하여 동일하게 두 경우로 규격화 할 수 있었다. 즉, 안전풍속 35m·s-1와 안전적설심 40cm에서 구조적으로 안전한 서까래 규격은 Φ31.8×1.5t@600이었으며, 안전풍속 35m·s-1와ss 안전적설심 35cm에서는 서까래 Φ25.4×1.5t@600인 것으로 분석되었다. 덕면으로부터 곡부보까지의 높이는 안전적설심보다는 안전풍속에 직접적인 영향을 미치는 것으로 분석되었으며, 처마를 높임에 따라 측면풍속에 대해서는 방풍벽파이프(측벽서까래)를, 전후면 풍속에 대해서는 마구리기둥의 규격을 강화하여야 하는 것으로 분석되었다.
