论文摘要
zevatron是一种设想的加速器方案，可将粒子加速到Zev Energies（1 Zev = $ 10^{21} $ eV）。已经提出了方案，最值得注意的是内部冲击模型，以解释自1962年以来一直在偶发地检测到地球的超高能量宇宙射线（UHECR）颗粒的加速度。在这里，Cyclotron自动共振加速度（CARA）机制被量身定制并表现出可能是颗粒的过程，这是一种属性的行为。二进制系统或超新星爆炸。此类事件导致高能颗粒和超强光束辐射的发射。在同时存在超强磁场的情况下，可以满足回旋体自动谐振的条件。因此，卡拉可以像{\ it增强}的作用，对于通过冲击波在其祖细胞中预先加速的颗粒，可能是其他方式。作为示例，显示出氢，氦气和铁-56的核可以通过cara到达ZEV能量，在此条件下，在颗粒的情况下，同时围绕超强磁场的线旋转，也会在超强度辐射场的波浪上冲浪。当考虑到辐射反应时，粒子获得的ZEV能量可能会降低小于数量的ZEV能量，如果谐振条件丢失了大约小于20 \％。
A Zevatron is an accelerator scheme envisaged to accelerate particles to ZeV energies (1 ZeV = $10^{21}$ eV). Schemes, most notably the internal shock model, have been proposed to explain the acceleration of ultra-high-energy cosmic-ray (UHECR) particles that have been sporadically detected reaching Earth since 1962. Here, the cyclotron auto-resonance acceleration (CARA) mechanism is tailored and used to demonstrate possible acceleration of particles ejected as a result of violent astrophysical processes such as the merger of a binary system or a supernova explosion. Such events result in emission of highly-energetic particles and ultra-intense beamed radiation. In the simultaneous presence of a super-strong magnetic field, the condition for cyclotron auto-resonance may be met. Thus CARA can act like a {\it booster} for particles pre-accelerated inside their progenitor by shock waves, possibly among other means. As examples, it is shown that nuclei of hydrogen, helium, and iron-56, may reach ZeV energies by CARA, under which conditions the particles, while gyrating around the lines of an ultra-strong magnetic field, also surf on the waves of a super-intense radiation field. When radiation-reaction is taken into account, it is shown that the ZeV energy gained by a particle can fall off by less than an order-of-magnitude if the resonance condition is missed by roughly less than 20\%.
