Commissioning of the new high-intensity ultracold neutron source at the Paul Scherrer Institut
Commissioning new high-intensity ultracold neutron source Paul Scherrer Institut
2010/12/29
Commissioning of the new high-intensity ultracold neutron (UCN) source at the Paul Scherrer Institut (PSI) has started in 2009. The design goal of this new generation high intensity UCN source is to s...
Determining source cumulants in femtoscopy with Gram-Charlier and Edgeworth series
Determining source cumulants femtoscopy Gram-Charlier Edgeworth series
2010/12/27
Lowest-order cumulants provide important information on the shape of the emission source in femtoscopy. For the simple case of noninteracting identical particles, we show how the fourth-order source c...
Neutrino physics with an intense \nuc{51}{Cr}source and an array of low-energy threshold HPGe detectors
Neutrino physics an intense \nuc{51}{Cr}source an array of low-energy threshold HPGe detectors
2011/1/4
We study some of the physics potential of an intense $1\,\mathrm{MCi}$ $^{51}\mathrm{Cr}$ source combined with the {\sc Majorana Demonstrator} enriched germanium detector array. The {\sc Demonstrator}...
A Simple Xray Spectrometer and PCbased Data Acquisition System for Newly Developed Xray Source Based on Laser Compton Scattering
laser Compton scattering Si(Li) detector energy resolustion
2009/10/28
A simple Xray spectrometer and a PCBased Data Acquisition System(DAS) have been developed newly in Shanghai Institute of Applied Physics(SINAP), Chinese Academy of Sciences(CA...
Design of magnet and control of the beam emittance for Penning H－ ion source
H－ ion source Magnetron ion source Penning ion source magnetic field gradient index
2009/8/14
The design requirement and principle of the deflection magnet for Magnetron and Penning H－ ion source are discussed. It is proved that there exists a maximum emittance for the beam that may be transf...

Two-pion interferometry for a partially coherent evolution source
HBT correlation function partially coherent evolution source multiple scattering source collective expansion
2009/7/31
We give the formulas of two-pion Hanbury-Brown-Twiss (HBT) correlation function for a partially coherent evolution pion-emitting source, using quantum probability amplitudes in a path-integral formali...
