摘要:

TRI $μ$ P设施的结构已经完成并投入使用。该设施生产放射性核素以研究基本相互作用和对称性。一个重要的特点是捕获放射性原子的可能性,以获得和保持一个纯的无衬底的样品进行精确测量。在TRI $μ$ P设施中,生产靶之后是磁分离器,其中放射性同位素在逆反应运动学中生产。$^{21}$ Na的分离度可达99.95%。研制了一种新型的发射式热电离装置,用于阻止高能同位素的产生。约50%的停止$^{21}$ Na可以被提取并作为低能量单电荷离子传输到射频四极冷却器和聚束器中,传输效率为35%。离子通过漂移管和低能静电束线无损地传输到实验装置中。这些离子可以在热金属箔上中和,产生的原子可以存储在磁光阱中。这一原理的功能已经用从热电离器中提取的稳定的Na进行了证明,接下来将是放射性核束。

英文摘要:

The structures for the TRI$μ$P facility have been completed and commissioned. At the facility radioactive nuclides are produced to study fundamental interactions and symmetries. An important feature is the possibility to trap radioactive atoms in order to obtain and hold a pure substrate-free sample for precision measurements. In the TRI$μ$P facility a production target is followed by a magnetic separator, where radioactive isotopes are produced in inverse reaction kinematics. Separation up to 99.95% could be achieved for $^{21}$Na. A novel transmitting thermal ionizing device was developed to stop the energetic isotopes. Some 50% of stopped $^{21}$Na could be extracted and transported as low energy singly charged ions into a radio frequency quadrupole cooler and buncher with 35% transmission efficiency. The ions are transported lossless via a drift tube and a low energy electrostatic beam line into the experimental setup. Such ions can be neutralized on hot metal foils and the resulting atoms can be stored in a magneto-optical trap. The functioning of that principle was demonstrated with stable Na extracted from the thermal ionizer, radioactive beams will follow next.
