6.高能粒子加速器（High energy particle accelerator）
由于納米(mi)(mi)晶(jing)具有(you)(you)至少(shao)1.2特斯拉的(de)(de)高飽(bao)和磁(ci)通(tong)密度(du)，適(shi)當的(de)(de)納米(mi)(mi)晶(jing)鐵芯是(shi)同步回旋加速(su)器空(kong)腔調諧組件(jian)的(de)(de)首選解(jie)決(jue)方案。在(zai)非常有(you)(you)限的(de)(de)空(kong)間進(jin)行的(de)(de)粒子束(shu)(shu)偏轉集(ji)(ji)束(shu)(shu)器或壓縮集(ji)(ji)束(shu)(shu)器，通(tong)過使(shi)用納米(mi)(mi)晶(jing)鐵芯，所需的(de)(de)長度(du)比鐵氧體鐵芯通(tong)常可以(yi)減少(shao)50%,但缺(que)點是(shi)工作(zuo)期間功(gong)耗顯著增加。不(bu)過,由于他們的(de)(de)低阻抗,納米(mi)(mi)晶(jing)鐵芯也避免了與離子束(shu)(shu)不(bu)利(li)的(de)(de)交互作(zuo)用,因此,納米(mi)(mi)晶(jing)鐵芯在(zai)全世界(jie)的(de)(de)幾個粒子束(shu)(shu)加速(su)器設(she)施中得以(yi)使(shi)用。
Due to the high saturation flux density of at least 1,2Tesla suitable nanocrystalline cores are the preferred solution for the tuning elements in synchrotron cavities. Related applications like particle beam de-bunchers or bunch compressors are often very much limited in space. By the use of nanocrystalline cores, the required length compared to Ferrite cores can be reduced by typically 50% - but with the disadvantage of significantly higher power consumption during operation. But due to their low impedance, the nanocrystalline cores also avoid unfavorable interactions with the ion beam and thus, they are used in several particle beam accelerator installations worldwide.
