Van de Graaff generator Model : VDG20

The Van de Graaff generator is an electrostatic machine that generates high voltages, widely used in scientific research and educational demonstrations. Invented by American physicist Robert J. Van de Graaff in 1931, it operates by using a moving belt to transport electric charge to a large metal sphere. As the belt moves, it accumulates charge, which is then deposited onto the sphere, creating a significant electric potential. The generator then produce voltages exceeding several million volts, making it invaluable in nuclear physics, particle physics, and radiation research. It has applications in various fields, including medical treatments and materials science. The Van de Graaff generator illustrates fundamental principles of electrostatics and has been instrumental in advancing our understanding of atomic and subatomic processes.

范氏起電機是一種產生高電壓的靜電力，廣泛用於科學研究和教育演示。它是由美國物理學家羅伯特·范德格拉夫 (Robert J. Van de Graaff) 於 1931 年發明，其工作原理是利用移動的皮帶將電荷傳輸到一個大的金屬球上。當皮帶移動時，它會積聚電荷，然後這些電荷沉積在球體上，產生顯著的電位。此發生器產生的電壓超過數百萬伏，在核物理、粒子物理和輻射研究中具有無價的價值。它可應用於醫療和材料科學等各個領域。范德格拉夫起電機闡明了靜電學的基本原理，對增進我們對原子和亞原子過程的理解發揮了重要作用。
