An MgB2 Superconducting Joint with its own Heat-Treatment Schedule
<|begin_of_text|><|start_header_id|>system<|end_header_id|> You are a research archivist expert in dataset metadata. Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'We suggested an MgB2 joint process with its own heat-treatment schedule to apply it for our 1.5-T MgB2 “finger” MRI magnet. In fabricating the MgB2 magnet, the optimal heat-treatment schedule to attain a reproducible and high critical current is different in a joint and a coil. To solve this problem, we introduced an additional heating system, which is composed of a cartridge heater and a thermocouple connected with a copper block, into a box-type furnace. Then, we carried out heattreatments with exclusively increasing the joint-part temperature above theMgmelting point of 645 °C—the jointwas actually heated up to 700 °C.We evaluated a critical current and a crystal structure of the obtained MgB2 joint. From experimental results, we found that the joint heated with the own heat-treatment schedule, which is 700 °C for 1 h+600°C for 11 h,' .
