Overview of the NASA space radiation laboratory

The NASA Space Radiation Laboratory (NSRL) is a multidisciplinary center for space radiation research funded by NASA and located at the Brookhaven National Laboratory (BNL), Upton NY. Operational since 2003, the scope of NSRL is to provide ion beams in support of the NASA Humans in Space program in radiobiology, physics and engineering to measure the risk and ameliorate the effect of radiation in space. Recently, it has also been recognized as the only facility in the U.S. currently capable of contributing to heavy ion radiotherapy research. Finally, this work contains a general overview of NSRL structure, capabilities and operation.

Sens-Tech XDAS Readout System

In December 2010, the old British Phototube manufacture, EMI, called about their new product -after the company changed its name. The system they are marketing is very suitable for our use, digitizing charge from the detector in the beam line. Their system was capable of a large number of channels. Initially, we were offered a system based on integration with CCD readout. It is called the HE system. After many exchanges we bought a 64-channel system. It came pre assembled.

Secondary Emission Chamber Calibration with Scintillator (V.1.0)

We report on a study of the behavior of a secondary emission chamber (SEC) when placed in a beam of high energy charged particles. We show the dependence of the SEC signal on the charge and velocity of the primary beam particles when using protons, and Iron ions. We calibrate the response of the SEC to ions by first using a plastic scintillator to count particles traversing the SEC, and transfer the calibration to an ion chamber that can operate at a high enough rate to characterize the SEC. The calibration is determined for the two different ion species and two different energies
