SOLar POLarimeter for Hard X-Rays
(SOLPOL)

The following pictures depict the development of SOLPOL science model. This device is designed to measure the linear polarization of hard X-rays (50-300 keV).

The first SOLPOL prototype, designed to demonstrate basic hard X-ray polarimetry techniques. In this case, an array of independent plastic scintillating blocks surrounded a central NaI detector. Polarimeter events scatter from the plastic into the NaI.

View of the SOLPOL science model components. On the right is the 5-inch Hamamatsu PSPMT used to read out signals from the array plastic scintillator elements (seen in the center). Each plastic scintillator elements is 5 mm square and 2-inches long. On the left is the CsI / MAPMT assembly that is inserted into the center of the plastic array.
