High-gain free-electron lasers (FELs) are capable of generating femtosecond x-ray pulses with peak brilliances many orders magnitude higher than at other existing sources. In order to fully exploit the opportunities offered by these light in time-resolved experiments, an unprecedented synchronization accuracy is required. this Letter, we distributed pulse train a mode-locked fiber laser stability different locations linear accelerator soft FEL FLASH. A novel electro-optic detection scheme...
The subject of this paper is the design and construction a new generation superconducting cavity accelerator measurement control system. old system based on single digital signal processor (DSP). uses large programmable array circuit (FPGA) instead, with multi-gigabit optical link. Both systems now work in parallel Free Electron Laser Hamburg (FLASH). differences between are shown, results working machine. major advantage bigger area stability machine loop.
In forthcoming deuterium-tritium (DT) experiments on JET a significant population of alpha-particles will be produced. For operating alpha-particle diagnostics at high DT neutron fluxes, specific improvements have to made. Proposed new detectors for gamma-ray measurements based CeBr3 and LaBr3:Ce scintillators. They are characterized by good energy resolution, relatively detection efficiency few MeV gamma-rays fast response time. An overview scintillator parameters is presented. A...
Neutron activation analysis is a well-known method for determining isotopic composition of dierent materials.Due to the non-destructive nature it can also be used in homeland security application, example an inspection packages unknown origin.For this purpose hazardous material detection system (SWAN) was built.The device has automatic decision algorithm that analyze spectrum gamma rays 12 C, 14 N and 16 O.Characteristic ratio these lines gives requested answer.Using such simple approach...
A Modular COsmic Ray Detector (MCORD) was prepared for use in various physics experiments. MCORD detectors can be used laboratory measurements or become a part of large measurement sets. as muon detector, veto system, tool supporting the testing and calibration other detectors. also work stand-alone device scientific commercial purposes. The basic element is one section consisting eight oblong scintillators with double-sided light reading performed by silicon photomultipliers (SiPMs). This...
