A new fluorescent dye with large Stokes shift and excellent photo-stability for live cell imaging has been developed.
Speckle patterns generated by the intermodal interference of multimode fibers enable accurate broadband wavelength measurements.However, measurement speed is limited frame rate camera that captures patterns.We propose a compact and cost-effective ultrafast wavemeter based on multicore fibers, which employs spectral-spatialtemporal mapping.The speckle spectral-tospatial mapping, then sampled fiber into pulse sequence to implement spatial-to-temporal mapping.A high-speed single-pixel...
Abstract The design, construction, and commissioning of a novel liquid helium-free (LHe-free) Nb 3 Sn superconducting radio frequency (SRF) electron accelerator at the Institute Modern Physics Chinese Academy Sciences (IMP, CAS) will be presented. A 650 MHz 5-cell elliptical cavity was coated using tin vapor diffusion method for beam acceleration. slowly cooled down across 18 K with high-precision collaborative control ten individual GM cryocoolers. This process accompanied by characteristic...
In this paper, the printed D-Band patch antenna and 1×4 array are designed on quartz glass substrate, which suitable for millimeter wave applications. The central frequency of is at 146 GHz. Because there no metal vias in gold belt utilized to connect signal ground top surface with bottom substrate. relative position affects resonant antenna. prototypes antennas successfully fabricated measured. measured gain unit 6.6 dBi 11.4 dBi, respectively, S11 below -10 dB bandwidth about 6.4% 5.9%,...
Significant transient beam loading effects were observed during commissioning tests of prototype II the injector for Accelerator Driven Sub-critical (ADS) system, which took place at Institute Modern Physics, Chinese Academy Sciences, between October and December 2014.During these experiments performed with CW operation cavities pulsed current, system was configured to make use a digital low level radio frequency (LLRF) controller.The originally operated in mode simple PID feedback control...
To test superconducting cavities, a vertical system has been designed and set up at the Institute of Modern Physics (IMP). The design is based on VCO-PLL hardware NI Labview software. HWR010#2 cavity shows that function this satisfactory for testing low frequency cavity.
Off-line high-power tests of the fundamental power couplers prior to their on-line operations are importance for ensuring operating reliability and stability. To test using a limited supply effectively, movable standing wave (SW) resonant system with an extraordinary gain has been developed at Institute Modern Physics, Chinese Academy Sciences (IMP, CAS). The consists resonator having two shorts enhancement movement SW field, tunable secondary coupler feeding into without reflection....
We propose a precise polarization-measurement system based on multimode fiber speckle. Convolutional neural network is used to achieve accurate identification of polarization states. The resistant indoor temperature variation and the mean square error between actual predicted Stokes parameters less than 0.001.
Institute of Modern Physics (IMP), Chinese Academy Sciences, is the first domestic institute that widely applied solid-state power amplifier (SSPA) to linear accelerator project from C-ADS started since 2011. Until now, same design has already been considered for two large-scale scientific facilities in Guangdong Province southeast China, China initiative Accelerator Driven System and High Intensity Heavy-ion Facility. In a recent decade construction, large amount valuable experience source...
This paper presents a D-Band wire bond interconnect method for low-cost, wide bandwidth transmission on quartz glass substrate. A novel compensation technique bonding-wire interconnection based single-objective optimization is proposed. design has conductor-backed coplanar waveguide (CB-CPW) structure and precisely modeled bonding-wire. The achieved good impedance matching in the D-band, measurement results demonstrate that relative of -10 dB reflection can be about 16.4%.
