To obtain such positron microbeam, it is necessary to use objective lenses, which are commonly used in the electron microscopy. We also attempted to form the positron microbeam using a positron beam for the positron diffraction experiment and a SEM optics [6]; [7] ; [8].
1 BERLIN â Ikea has long been famous for its inexpensive, some-assembly-required furniture. 2  A report by auditors at Ernst & Young concluded that Ikea, a Swedish company, knowingly benefited from forced labor in the former East Germany to manufacture some of its products in the 1980s.
