全超导磁体托卡马克装置英语作文Title:Fully Superconducting Tokamak (FST)A Fully Superconducting Tokamak (FST) is a pioneering design in the realm of nuclear fusion research, aiming to harness the power of the stars for sustainable energy production. This essay will provide an overview of FST technology, its operational principles, and its significance in the quest for clean energy.The FST is based on the Tokamak configuration, a doughnut-shaped (toroidal) device that uses magnetic fields to confine plasma, the hot, ionized gas necessary for nuclear fusion reactions. Unlike traditional tokamaks that use copper coils for magnetic confinement, FSTs employ superconducting coils. These coils, operating at extremely low temperatures, can maintain strong magnetic fields with minimal electrical resistance, significantly enhancing the device's efficiency and operational time.The heart of an FST lies in its superconducting coils, which are cooled to cryogenic temperatures, typically near absolute zero, using liquid helium. At these temperatures, the coils become superconductors, meaning they can conductelectricity with zero resistance. This property allows for the creation of powerful, stable magnetic fields that can confine the plasma in the toroidal chamber for extended periods.The plasma, consisting of hydrogen isotopes such as deuterium and tritium, is heated to temperatures exceeding 100 million degrees Celsius, the conditions necessary for nuclear fusion to occur. The magnetic fields generated by the superconducting coils prevent the plasma from touching the chamber walls, which would cool the plasma and disrupt the fusion process.FST technology offers several advantages over conventional tokamaks. Firstly, the use of superconducting coils allows for a more compact design, reducing the overall size and cost of the device. Secondly, FSTs can operate continuously for extended periods, potentially leading to a steady-state fusion reactor that can provide a constant source of electricity. This is in contrast to traditional tokamaks, which can only operate in short bursts due to the limitations of their copper coils.The development of FSTs represents a significant step forward in the pursuit of clean, sustainable energy. Nuclear fusion, if successfully harnessed, could provide a virtuallylimitless supply of energy without the greenhouse gas emissions associated with fossil fuels or the radioactive waste produced by nuclear fission. FSTs, with their improved efficiency and operational stability, bring the dream of fusion power closer to reality.In conclusion, the Fully Superconducting Tokamak (FST) is a cutting-edge technology that promises to revolutionize the field of nuclear fusion. By employing superconducting coils to confine plasma, FSTs offer a more efficient and stable approach to fusion energy production. As research in this area continues, FSTs could pave the way for a future where clean, sustainable energy is a global reality.。

Wang (dxwpling (MC) process, which is regarded as one of the variants of the BZ process (Blandford 1999; van Putten 1999; Li 2000b, 2002; Wang, Xiao & Lei 2002, hereafter W02). It is shown in B00 that about 1053 ergs are available to power both a GRB and a SN. However, they failed to distinguish the fractions of the energy for these two objects. More recently, van Putten and his collaborators (van Putten 2001; van Putten & Levinson 2003, hereafter P03) worked out a poloidal topology for the open and closed magnetic field lines, in which the separatrix on the horizon is defined by a finite half-opening angle. The duration of a GRB is set by the lifetime of the rapid spin of the BH. It is found that GRBs and SNe are powered by a small fraction of the BH spin energy. This result is consistent with observations, i.e., duration of GRBs of tens of seconds, true GRB energies distributed around 5 × 1050 ergs (Frail et al. 2001), and aspherical SNe kinetic energies of 2 × 1051 ergs (Hoflich et al. 1999). Very recently, Lei et al. (2005, hereafter Lei05) proposed a scenario for GRBs in type Ib/c SNe invoking the coexistence of the BZ and MC processes. In Lei05 the GRB is powered by the BZ process, and the associated SN is powered by the MC process. The overall time scale of the GRB is fitted by the duration of the open magnetic flux on the horizon. Besides the features of high energy released in very short durations most GRBs are highly variable, showing very rapid variations in flux on a time scale much shorter than the overall duration of the burst. Variability on a time scale of milliseconds has been observed in some long bursts (Norris et al. 1996; McBreen et al., 2001; Nakar and Piran, 2002). Unfortunately, the origin of the variations in the fluxes of GRBs remains unclear. In this paper we intend to discuss the mechanism for producing the variations in the fluxes of GRBs by virtue of the screw instability in BH magnetosphere. It is well known that the magnetic field configurations with both poloidal and toroidal components can be screw-unstable. According to the Kruskal-Shafranov criterion the screw instability will occur, if the toroidal magnetic field becomes so strong that the magnetic field line turns around itself once or more (Kadomtsev 1966; Bateman 1978). Some authors have addressed the screw instabilities in BH magnetosphere. Gruzinov (1999) argued that the magnetic field with a bunch of closed field lines connecting a Kerr BH with a disk can be screwunstable, resulting in the release of magnetic energy with the flares at the disk. Li (2000a) discussed the screw instability of the magnetic field in the BZ process, leading to a stringent upper bound to the BZ power. Wang et al. (2004, hereafter W04) studied the screw instability in the MC process. They concluded that this instability could occur at some place away from the inner edge of the disk, provided that the BH spin a∗ and the power-law index n for the variation of the magnetic field on the disk are greater than some critical values. In this paper we attempt to combine the screw instability of the magnetic field with the coexistence of the BZ and MC processes. To facilitate the description henceforth we refer to the screw instability of the magnetic field occurring in the BZ and MC processes as SIBZ and SIMC, respectively. It is shown that both SIBZ and SIMC can occur, provided that the following parameters are greater than some critical values: (1) the BH spin, (2) the power-law index describing the variation of the magnetic field at the disk, and (3) the vertical height of the astrophysical load above the equatorial plane of the Kerr BH. The features of several GRB-SNe are well fitted in our model. (1) The overall duration of the GRBs is fitted by the evolution of the half-opening angles. (2) The true energies of several GRBs are fitted

INTRODUCTION
Recently, observations and theoretical considerations have linked long-duration GRBs with ultrabright Type Ib/c supernovae (SNe; Galama et al. 1998, 2000; Bloom et al. 1999). The first candidate was provided by SN 1998bw and GRB 980425, and the recent HETE-II burst GRB 030329 has greatly enhanced the confidence in this association (Stanek et al. 2003; Hjorth et al. 2003). Extremely high energy released in very short time scale suggests that GRBs involve the formation of a black hole (BH) via a catastrophic stellar collapse event or possibly a neutron star merger, implying that an inner engine could be built on an accreting BH. Among a variety of mechanisms of powering GRBs the Blandford-Znajek (BZ) process (Blandford & Znajek, 1977) has its unique advantage in providing “clean” (free of baryonic contamination) energy by extracting rotating energy from a BH and transferring it in the form of Poynting flow in the outgoing energy flux (Lee et al. 2000, hereafter Lee00; Li 2000c, hereafter Li00). Not long ago Brown et al. (2000, hereafter B00) worked out a specific scenario for a GRB-SN connection. They argued that the GRB is powered by the BZ process, and the SN is powered by the
