Effective measures have been adopted for increasing the negative ion beam intensity and decreasing the emittance of the Model 860A high intensity sputter source through enhancing the cathode voltage and rebuilding a focusing geometry electrode system. By using a Ta sheet spherical geometry ionizer the sputtering region has been narrowed down to a diameter of ~ 0.75mm. Three porcelain rods replacing the original cathode insulator make the target voltage reach 10kV. The negative ion beam intensity of some...

Effective measures have been adopted for increasing the negative ion beam intensity and decreasing the emittance of the Model 860A high intensity sputter source through enhancing the cathode voltage and rebuilding a focusing geometry electrode system. By using a Ta sheet spherical geometry ionizer the sputtering region has been narrowed down to a diameter of ~ 0.75mm. Three porcelain rods replacing the original cathode insulator make the target voltage reach 10kV. The negative ion beam intensity of some species has increased by 300% and the transmission efficiency is improved. These measures have improved operation conditions of the 2×1.7MV Tandetron for large dose high energy ion implatation.

球面电离器的采用使溅射区域缩小到直径~0.75mm;用3根远离溅射区的瓷柱取代原来绝缘阴极的瓷环,可使溅射电压在10kV以内稳定工作。这些改进措施使860A的部分负离子品种的流强提高了近300%,传输效率得以提高,从而为2×1.7MV串列加速器进行大注量高能离子注入改善了条件。

Altogether 28 samples, mainly including glazes and bodies of ancient Chinese Ru porcelain, were analyzed by NAA technique and the contents of 36 elements were compared The scatter analysis for nine fingerprint-elements indicates that almost all ancient Chinese Ru porcelain samples had nearly identical and long-term stable source of raw materials although they were fired in different kilns, at varying time and with distinet colors, and moreover, the source of raw materials for modern Ru porcelain seems to approach that for ancient one The close provenance relation between ancient Jun porcelain and ancient Ru procelain is also preliminarily verified The glaze material of Jingdezhen white porcelain is totally different from all other samples, showing that the former came from a separate source

将古汝瓷、现代汝瓷的釉和胎等28个样品进行中子活化分析(NAA),测定每个样品中36种元素的含量,从中选取9种指纹元素进行散布分析。结果表明,除少数样品外,这批釉色迥异、出自众多不同窑口、不同时间烧制的古汝瓷,有着长期的、稳定的、基本相同的原料来源。初步分析了古钧瓷与古汝瓷相近的起源关系。现代汝瓷与古汝瓷原料产地基本相同。现代景德镇高白瓷釉料有别于所有其他样品。
