【摘要】：在高能同步輻射光源驗(yàn)證裝置(HEPS-TF)的插入件系統(tǒng)中,將要研制一臺(tái)基于鐠鐵硼永磁鐵的低溫波蕩器(CPMU)。低溫波蕩器要求磁鐵磁極陣列工作溫度要在85 K以下,同時(shí)整個(gè)大梁軸向的溫度梯度不超過1.5 K/m。經(jīng)過理論計(jì)算,低溫波蕩器在有束流情況下的熱負(fù)荷約660 W@80 K。為冷卻低溫波蕩器大梁磁結(jié)構(gòu),設(shè)計(jì)了一套過冷液氮閉循環(huán)迫流冷卻系統(tǒng)。為了確保磁鐵有更好的低溫效果和溫度均勻性,低溫波蕩器內(nèi)大梁采用了雙通道冷卻設(shè)計(jì)。最后,根據(jù)低溫流程設(shè)計(jì)了可行的機(jī)械結(jié)構(gòu),稱其為液氮過冷器冷箱。
[Abstract]:In the insert system of HEPS-TFM, a low-temperature waver based on praseodymium iron-boron permanent magnet is to be developed. At the same time, the axial temperature gradient of the whole beam is not more than 1.5 K / m. The theoretical calculation shows that the thermal load of the low temperature waver is about 660 W @ 80K. it is a magnetic structure for cooling the beam of the low temperature waver. A set of supercooled liquid nitrogen closed circulation forced flow cooling system is designed. In order to ensure the magnet has better low temperature effect and temperature uniformity, double channel cooling design is used in the beam of low temperature waver. According to the low temperature process, a feasible mechanical structure is designed, which is called the liquid nitrogen supercooler cooler.
