Jinghui Wang is a postdoc fellow in the Department of Radiology at Stanford University. His research areas include: Radiation Detection, Semiconductor devices, and Linear Accelerators. More specifically, he jointly use Monte Carlo tools (MCNP, SRIM, PENELOPE) and finite-element softwares (TCAD, COMSOL, ANSYS) to study the generation, transportation, and detection of ionizing radiations (Neutron, X-rays, electrons and heavy-charged particles) with semiconductor-based devices (Si, GaN, SiC, GaAs, and CdTe);

He currently working on two research projects:
1) High spatial resolution photon detectors used in computed tomography (CT) systems.
Initial charge cloud formation, charge migration and detection, pulse-pile up, charge sharing.
2) Treatment head in radiotherapy system:
Electron energy deposition in tungsten and W25Re X-ray target, heat transfer in X-ray target. Dose distribution in water phantom.

  • Thermal limits on MV x-ray production by bremsstrahlung targets in the context of novel linear accelerators. Medical physics Wang, J., Trovati, S., Borchard, P. M., Loo, B. W., Maxim, P. G., Fahrig, R. 2017; 44 (12): 6610–20


    To study the impact of target geometrical and linac operational parameters, such as target material and thickness, electron beam size, repetition rate, and mean current on the ability of the radiotherapy treatment head to deliver high-dose-rate x-ray irradiation in the context of novel linear accelerators capable of higher repetition rates/duty cycle than conventional clinical linacs.The depth dose in a water phantom without a flattening filter and heat deposition in an x-ray target by 10 MeV pulsed electron beams were calculated using the Monte-Carlo code MCNPX, and the transient temperature behavior of the target was simulated by ANSYS. Several parameters that affect both the dose distribution and temperature behavior were investigated. The target was tungsten with a thickness ranging from 0 to 3 mm and a copper heat remover layer. An electron beam with full width at half maximum (FWHM) between 0 and3 mm and mean current of 0.05-2 mA was used as the primary beam at repetition rates of 100, 200, 400, and 800 Hz.For a 10 MeV electron beam with FWHM of 1 mm, pulse length of 5 μs, by using a thin tungsten target with thickness of 0.2 mm instead of 1 mm, and by employing a high repetition rate of 800 Hz instead of 100 Hz, the maximum dose rate delivered can increase two times from 0.57 to 1.16 Gy/s. In this simple model, the limiting factor on dose rate is the copper heat remover's softening temperature, which was considered to be 500°C in our study.A high dose rate can be obtained by employing thin targets together with high repetition rate electron beams enabled by novel linac designs, whereas the benefit of thin targets is marginal at conventional repetition rates. Next generation linacs used to increase dose rate need different target designs compared to conventional linacs.

    A real-time quantification of Li transport using a nondestructive neutron method to measure the Li distribution upon charge and discharge in a Li-ion cell is reported. By using in situ neutron depth profiling (NDP), we probed the onset of lithiation in a high-capacity Sn anode and visualized the enrichment of Li atoms on the surface followed by their propagation into the bulk. The delithiation process shows the removal of Li near the surface, which leads to a decreased coulombic efficiency, likely because of trapped Li within the intermetallic material. The developed in situ NDP provides exceptional sensitivity in the temporal and spatial measurement of Li transport within the battery material. This diagnostic tool opens up possibilities to understand rates of Li transport and their distribution to guide materials development for efficient storage mechanisms. Our observations provide important mechanistic insights for the design of advanced battery materials.
