Abstract This paper presents a heavy-ion in-beam PET, referred to as ibPET with specifically custom designed data acquisition system, which was constructed and tested at the Heavy Ion Medical Machine (HIMM) beam-line, HICTC in Wuwei. The system of has undergone several upgrades during years, And its processing capability now exceeds one million events per second channel. To achieve optimal performance under existing conditions, we coincident noise equivalent count (NEC) different time...
The half-size prototype of the multi wire drift chamber (MWDC) for cooling storage ring (CSR) external-target experiment (CEE) was assembled and tested in 350 MeV/u Kr+Fe reactions on heavy ion research facility Lanzhou (HIRFL). consists 6 sense layers, where wires are stretched three directions X, U V, meeting $0^\circ$, $30^\circ$ $-30^\circ$ with respect to vertical axis, respectively. sensitive area is $76 {\rm cm} \times 76 cm}$. amplified shaped signals from anode digitized a serial...
Typical white LED has limited energy beyond the band of (420-720) nm, which is not suitable as a transferring standard for spectral radiant flux, irradiance.An extended wavelength enough intensity in whole visible range been developed, by six dies and RGB phosphor.The spectrum stability developed was evaluated possibility it to be used luminous flux lamp studied 2m integrating sphere-spectroradiometer, testing result shows could worked reference calibrate generally inside uncertainty.
