回旋加速器是现行高中物理教材重点介绍的电学器件,它是用来加速带电粒子以获得“高能炮弹”的仪器。在学习回旋加速器时,除了要搞清楚它的基本结构、明白它的基本功能外,还应特别注意以下几个问题:1.在计算时忽略带电粒子在两个D形盒的缝隙中(即电场中)的运动时间,所以带电粒子在D形盒中的运动周期T=2πm/qB,与运动速度v、圆周半径R无关。 Cyclotron is the current high school physics teaching material focuses on electrical devices, it is used to accelerate the charged particles to obtain “high-energy shells ” instrument. In studying the cyclotron, in addition to its basic structure to understand and understand its basic functions, but also pay particular attention to the following questions: 1. In the calculation of the neglected charged particles in the gap between the two D-box (ie Electric field) movement time, so the charged particles in the D-box movement cycle T = 2πm / qB, and the speed of motion v, the radius of the circle R has nothing to do.
