We have started a measurement campaign of numerous methanol isotopologs in low-lying torsional states order to provide extensive line lists for radio astronomical observations from an adequate spectroscopic model and investigate how the intricate vibration-torsion-rotation interactions manifest themselves spectra different isotopic species. After CD$_3$OH CD$_3$OD, we turn our focus CH$_3$OD, which is important species studying deuteration prestellar cores envelopes that enshroud protostars....
A bridge arm prototype of ITER poloidal field (PF) converter modules has been designed and fabricated. Non-cophase counter parallel connection is chosen as the structure prototype. Among all factors affecting current sharing, main one. During design prototype, a novel method based on inductance matrixes employed to improve sharing arm. The test results show that performance much better than relevant requirement, matrix very effective analyze solve problems thyristor converters.
Power impact frequently occurs during operation of shock loads, such as fusion devices, threatening the stable power system. Meanwhile, both short-time high pulse and long-time steady exist, which have distinct time scales amplitude characteristics. Currently, capacity supply system is designed according to maximum impulse power, causing large redundancy cost. Aiming at this issue, hybrid scheme based on energy storage technology with density provides a potential approach. However, little...
The China fusion engineering test reactor is a new tokamak device. central solenoid (CS) model coil, which responsible for developing and verifying the key manufacturing methods of superconducting magnet, now under design. rating current coil 47.65 kA total magnetically stored energy reaches 407 MJ, so quench protection required to discharge this huge energy. This paper gives description CS coil. circuit system designed, consists direct breaker, resistor, diode, fuse. main parameters these...
The central solenoid (CS) model coil (CSMC), which has a high stored energy, is developed to validate the CS manufacturing methods for China Fusion Engineering Test Reactor (CFETR). designed operation current of 47.65 kA. maximum rate magnetic field 1.5 T/s. energy 407.6 MJ. A set verification test will be conducted after manufacture, so CSMC power supply, generates operation, and quench protection, could quickly release are required. main circuit topology supply was according requirements...
The Institute of Plasma Physics, Chinese Academy Sciences was contracted by General Atomics Company to develop a superconducting feeder system containing pair 50-kA high-temperature (HTS) current leads for ITER central solenoid magnet test. These HTS (HTSCL) are based on the previous lead design experiences. However, vertical assembly HTSCL which is different from ITER's horizontal causes water leakage in insulation flange during initial phase. Some improvements were recognized and expected...
Abstract When archaeological remains are buried under buildings or other obstacles, it is very difficult to detect them by performing the traditional electric resistivity tomography (ERT) which commonly sets out survey lines right above those remains. We presented an annular array ERT method solve problem. All electrodes were arranged around obstacles in form. The apparent data acquired through a special electrode shifting design. moved same serial number order with cross diagonal of 3D...
