Determination of solubility of uranium in liquid sodium

Ab-initio molecular dynamics study of lanthanides in liquid sodium

“…Moreover the knowledge of diffusivity in liquid metals is important for prediction of mass transfer rates which plays an important role in several applications such as corrosion [5], phase separation [6], and crystal growth [7]. However, the currently available data from experimental measurements is limited due to the difficulties associated with high temperature experiments and challenge of maintaining the integrity of the samples during the transfer of liquid metals between apparatuses [8]. Therefore, simulation methods provide useful and powerful alternatives to calculate the thermodynamic and transport properties for these systems at elevated temperatures.…”

Application of real-time digitization techniques in beam measurement for accelerators

“…High quality beam measurement is very important for accelerators, and thus is a worldwide research hotspot [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. A series of beam measurement techniques have been developed for different types of accelerators; however, with higher requirements for beam measurement and the development of electronics, more advanced measurement techniques need to be researched for more precise diagnostics of beam parameters.…”

“…Compared with the analog method, higher precision and flexibility can be achieved. Researchers in many institutes focus on research in this domain, including the Low Energy Demonstrator Accelerator (LEDA) [7,9] and Spallation Neutron Source(SNS) in the USA [10], Gesellschaft für Schwerionenforschung (GSI) in Germany [11], and the Institute of High Energy Physics (IHEP), Chinese Academy of Sciences, NRSL [14,15] and SSRF [12,13,17] in China. There are also companies specializing in beam measurement instrument design.…”

“…In its storage ring, up to 720 electron bunches circulate with a duty ratio of 500:220 and a Turn-By-Turn (TBT) frequency of f mc =693.964 kHz. Signals from the BPM pickups are high frequency pulses with a repetition frequency of 499.654 MHz (f mc ×720) and a pulse width of less than 200 ps [13], and the signal energy is located on the frequency of 499.654 MHz and its integral multiples in a frequency range beyond 10 GHz.
