APAKAH MAKSUD SYNCHROCYCLOTRON dalam CORSICA?
Synchrocyclotron
Synchrocyclotron adalah jenis siklotron khas, yang dipatenkan oleh Edwin McMillan, di mana frekuensi medan elektrik RF yang memvariasikan bervariasi untuk mengimbangi kesan relativistik apabila halaju zarah mula mendekati kecepatan cahaya. Ini adalah berbeza dengan siklotron klasik, di mana kekerapan ini berterusan. Terdapat dua perbezaan utama antara synchrocyclotron dan siklotron klasik. Dalam synchrocyclotron, hanya satu dee mengekalkan bentuk klasiknya, sementara tiang lain terbuka. Selain itu, kekerapan medan elektrik berayun dalam sinchrocyclotron menurun secara berterusan dan bukannya tetap berterusan untuk mengekalkan resonans siklotron untuk halaju relativistik. Satu terminal potensi elektrik berayun yang berbeza-beza secara berkala diterapkan kepada dee dan terminal lain adalah pada potensi tanah. Proton atau deuteron yang dipercepatkan dibuat untuk bergerak dalam lingkungan radii yang semakin meningkat. Percepatan zarah berlaku apabila mereka memasuki atau meninggalkan D. di pinggir luar, pancaran ion boleh dikeluarkan dengan bantuan deflector elektrostatik.
Definisi synchrocyclotron dalam kamus Corsica
Takrif synchrocyclotron dalam kamus adalah sejenis siklotron di mana frekuensi medan elektrik dimodulasi untuk membolehkan kesan relativistik pada halaju tinggi dan dengan itu menghasilkan tenaga yang lebih tinggi.

Such small values of the spiral pitch make it difficult to extract the accelerated
