Abstract The high-temperature gas generated by the missile launch will cause serious ablation to launcher. In order study thermal protection of device, a scheme arranging vertical upward water spray pipes in deflector is proposed, which realizes launcher vaporization and heat absorption principle liquid impact effect. Based on Mixture multiphase flow model, coupled with equation component trans...

Metasurfaces have enabled precise electromagnetic (EM) wave manipulation with strong potential to obtain unprecedented functionalities and multifunctional behavior in flat optical devices. These advantages precision functionality come at the cost of tremendous difficulty finding individual meta-atom structures based on specific requirements (commonly formulated terms EM responses), which makes ...

We present a GPU accelerated toolbox for shaping the light propagation through multimode fibre using a spatial light modulator (SLM). The light is modulated before being coupled to the proximal end of the fibre in order to achieve arbitrary light patterns at the distal end of the fibre. First, the toolbox optimises the acquisition time of the transformation matrix of the fibre by synchronous op...

We present a novel experimental setup in which magnetic and optical tweezers are combined for torque and force transduction onto single filamentous molecules in a transverse configuration to allow simultaneous mechanical measurement and manipulation. Previously we have developed a super-resolution imaging module which in conjunction with advanced imaging techniques such as Blinking assisted Loc...

In order to serve several experiments simultaneously, the Project X requires a programmable chopping system to deflect bunches from the initially 162.5MHz CW Hbeam. A helical 200 Ohm deflector is proposed, which needs a ±500V variable pulse length driver with ~2 ns rise/fall time at an average repetition rate of 33 MHz. The SLAC Hybrid MOSFET/driver Switch Module (HSM) has demonstrated 1ns swit...

Rubber dams have been used for the past 40 years in river and coastal engineering applications, in Australia and overseas. Despite the increasing interest for rubber dams, little information is available on their hydraulic performances. The overflow characteristics of inflated rubber dams are re-investigated. New analytical calculations provide information on the wall pressure distribution and ...

Light-sheet microscopy enables fast 3D, high-contrast imaging in biology and colloidal sciences. Recently, the controlled transport of living embryos or small colloids through stable glass capillaries is manifold interesting. Although they hardly impair the sample, glass capillaries spoil the image by generating significant aberrations of the illumination and detection light. Here, we analyze t...

An X-band Traveling wave Deflector mode cavity (XTD) has been developed at Radiabeam Technologies to perform longitudinal characterization of the subpicosecond ultra-relativistic electron beams. The device is optimized for the 100 MeV electron beam parameters at the Accelerator Test Facility (ATF) at Brookhaven National Laboratory, and is scalable to higher energies. The XTD is designed to oper...
