Endoscopic hemostasis for hemorrhage from an ileal diverticulum

Hemorrhage from a non-Meckelian jejunoileal diverticulum is rare, and it is generally difficult to diagnose the source of the bleeding. Here, we report the case of a 59-year-old male with hemorrhage from an ileal diverticulum. Contrast computed tomography scans demonstrated the ileal diverticulum and extravasation of the contrast medium around it. The diagnosis was then made by computed tomography scans, and endoscopic mechanical hemostasis was performed under colonoscopy with three metal clips. The management of hemorrhage from jejunoileal diverticula is discussed

Status of the JT-60SA project: An overview on fabrication, assembly and future exploitation

JT-60SA is a superconducting tokamak developed under the Satellite Tokamak Programme of the BroaderApproach Agreement between EU and Japan, and the Japanese national programme. It is designed tooperate in the break-even conditions for long pulse duration (typically 100 s), with a maximum plasmacurrent of 5.5 MA. Its scientific aim is to contribute at early realization of fusion energy, in support tothe ITER project and also to future DEMO devices by addressing key engineering and physical issues foradvanced plasma operation.The JT-60SA Project has shown steady progress in the last years: from the design of the main compo-nents, started in 2007 in a close collaboration between EU and Japan, continuing through the assembly inthe torus hall, started in January 2013 with the delivery of the first large European component, the Cryo-stat Base. Since then big milestones have been achieved, like the complete winding and pre-installationof the three lower Equilibrium Field (EF) coils, the welding of a 340◦of the Vacuum Vessel sectors, andthe completion of most of the Toroidal Field (TF) Coils.Outside the tokamak hall, large auxiliary plant like the Cryogenic System (CS) and the Quench ProtectionCircuits (QPC) have been fully installed and commissioned, while the Switching Network Units (SNU) andTF and EF coils Power Supplies (SCMPS) are completing installation on site. Other components such asCryostat Vessel, Thermal Shields, In Vessel Components and so forth are being manufactured and beingdelivered to Naka site for installation and commissioning.This paper gives technical progress on fabrication, installation and assembly of tokamak componentsand ancillary systems, as well as progress of JT-60SA Research Plan being developed jointly by EU andJapanese fusion communities

Development of the thermal insulation devices for the JT-60SA tokamak

This report focuses on the development of the thermal insulation devices including thermal shield (TS) and cryostat for the superconducting tokamak JT-60SA.1. Design, manufacturing and acceptance test were successfully completed by 2019 and installation will be done by March 2020.2. The technique and knowledge to realize high accuracy manufacturing and short time installation of these devices will contribute to the ITER construction and DEMO design.28th IAEAFusion Energy Conferenc
