碳/硼沉积和氘库存的演变过程中，从碳为主的过渡到全钨ASDEX升级。在以碳为主的机器中，在一个标准排放活动期间，约17克碳沉积在内部偏滤器和偏远地区。主要碳源是主室中的ICRH触角保护限制物。在用钨涂覆这些限制器之后，碳沉积减少到3-5g。剩余的碳主要来自外偏滤器撞击点的侵蚀。过渡到全钨机导致碳沉积进一步减少到约1g。1.3- 1.7克氘被捕获在偏滤器和偏远地区的碳/硼共沉积层中。在全钨机中，氘存量下降到0.16-0.24g。
The evolution of carbon/boron deposition and the deuterium inventory were determined during the transition from a carbon dominated to a full tungsten ASDEX Upgrade. In the carbon dominated machine about 17g of carbon were deposited at the inner divertor and in remote areas during one standard discharge campaign. Main carbon sources were the ICRH antennae protection limiters in the main chamber. After coating these limiters with tungsten the carbon deposition decreased to 3–5g. The remaining carbon originated mainly from erosion at the outer divertor strike point. Transition to a full tungsten machine resulted in a further decrease of the carbon deposition to about 1g. 1.3–1.7g deuterium was trapped in codeposited carbon/boron layers in the divertor and in remote areas during the carbon dominated campaigns. The deuterium inventory decreased to 0.16–0.24g in the full tungsten machine.
