The antiproton depth-dose curve measured with alanine detectors

In this paper we report on the measurement of the antiproton depth-dose curve, with alanine detectors. The results are compared with simulations using the particle energy spectrum calculated by FLUKA, and using the track structure model of Hansen and Olsen for conversion of calculated dose into response. A good agreement is observed between the measured and calculated relative effectiveness although an underestimation of the measured values beyond the Bragg-peak remains unexplained. The model prediction of response of alanine towards heavy charged particles encourages future use of the alanine detectors for dosimetry of mixed radiation fields.

The Fermi Large Area Telescope as a cosmic-ray electron detector

Successfully launched into a low-Earth orbit on June 11, 2008, the Fermi Large Area Telescope (LAT) is a pair conversion telescope specifically designed to survey the gamma-ray sky with unprecedented sensitivity and resolution. The broad list of exciting scientific results that the observatory has achieved in the first year of operation, though, is not limited to photon science, as it includes the first high-statistics measurement of the cosmic-ray electron spectrum for energies above 20 GeV. Here we thoroughly discuss the main aspects of the data analysis underlying this measurement and present the ongoing study aimed at lowering the energy threshold of the primary spectrum (measured by the LAT) as well as exploring the properties of the electron albedo population.

小鼠受100rad照射后组织荧光产物含量和硒谷胱甘肽过氧酶活性的变化

本文中实验测定了100rad受照小鼠肝、脾和睾丸组织的荧光产物含量以及肝和脾组织的Se-GSHPX活性。与对照组相比,在照后的15天内肝荧光产物的含量无明显变化;在照后7天至15天脾荧光产物含量明显增加(P<0.01);睾丸除照后3天降低外(P<0.05),在观察的7天内无明显变化。从照后1天至5天肝SeGSHPx活性增高(P<0.05),到照后7天有恢复趋势;脾Se-GSHPx活性在照后3天明显升高(P<0.01),照后5天和7天转为降低(P<0.05)。
