摘要

有一种新的磁性合金叫做Finemet，它具有非常恒定的/spl mu/'/sub p/Qf，高达/spl sim/ 2kg，并且在高磁通密度和温度下非常稳定。它可能是高梯度射频腔的良好候选者。然而，它有一个相当低的质量因子，因此是非常有损的。我们比较了Finemet与普通铁氧体在低能加速腔、空间电荷补偿插入和势垒腔中的优缺点。

Finemet versus ferrite-pros and cons

There is a new magnetic alloy called Finemet which has very constant /spl mu/'/sub p/Qf up to /spl sim/2 kG and is very stable at high magnetic flux density and temperature. It may be a good candidate for high-gradient RF cavities. However, it has a rather low quality factor and is therefore very lossy. We compare the pros and cons of Finemet versus the common ferrite, when used in low-energy accelerating cavities, insertion for space-charge compensation, and barrier cavities.
