摘要:

描述了一种周期长度为3.8mm的新型双折射波荡器的样机。波荡器是100个周期长。在本文所述的第一次测试中,波荡器在氦浴中冷却,结果表明,它可以像预期的那样工作,最大电流为1400 A。然后,用一个有效面积为(100 × 100)× 10 ^-6 m^2的微型霍尔探头测量波荡器场。计算和测量的场分布是一致的。在美因茨微波加速器MAMI的束流测试中,建立了一个低温恒温器,其中液氦间接冷却真空中的波荡器。目前正在对低温恒温器进行测试和优化。

英文摘要:

A prototype of a novel superconductive undulator with a period length of 3.8 mm is described. The undulator is 100 periods long. In the first tests described in this paper the undulator was cooled in a helium bath and it was shown that it can be operated as expected with a maximum current of 1400 A. Afterwards the undulator field was measured with a miniature Hall probe with an active area of (100x100)x10^-6 m^2. Calculated and measured field distributions are in good agreement. A cryostat for a beam test at Mainz microtron MAMI was built in which liquid helium cools indirectly the in-vacuum undulator. At the moment the cryostat is tested and optimized.
