Development of microcalorimeters for high resolution X-ray spectroscopy
Abstract We have been developing microcalorimeters for use in X-ray spectroscopy. These devices have very high spectral resolution (several eV) and high intrinsic quantum efficiency, making them particularly useful for astrophysical applications. Work has evolved over a 10 year period from simple pr...

| 520 | |a Abstract We have been developing microcalorimeters for use in X-ray spectroscopy. These devices have very high spectral resolution (several eV) and high intrinsic quantum efficiency, making them particularly useful for astrophysical applications. Work has evolved over a 10 year period from simple proof-of-concept devices to functional arrays. An energy resolution of 7.3 eV at 6 keV has been demonstrated for the smallest absorbers used, and a resolution of ∼12 eV for devices with a pixel area of ∼1/4 $ mm^{2} $. Present work is focused on making 36 pixel monolithic arrays with individual pixel areas of up to ∼1 $ mm^{2} $. As the size of the absorbing area is increased, high spectral resolution is more difficult to achieve not only because of the increased heat capacity, but also because of problems with uniform thermalization. We have observed non-ideal effects in large absorbers that must be controlled and minimized before the fabrication of low noise, larger area microcalorimeters can be accomplished. | ||

Development of microcalorimeters for high resolution X-ray spectroscopy |
| abstract |
Abstract We have been developing microcalorimeters for use in X-ray spectroscopy. These devices have very high spectral resolution (several eV) and high intrinsic quantum efficiency, making them particularly useful for astrophysical applications. Work has evolved over a 10 year period from simple proof-of-concept devices to functional arrays. An energy resolution of 7.3 eV at 6 keV has been demonstrated for the smallest absorbers used, and a resolution of ∼12 eV for devices with a pixel area of ∼1/4 $ mm^{2} $. Present work is focused on making 36 pixel monolithic arrays with individual pixel areas of up to ∼1 $ mm^{2} $. As the size of the absorbing area is increased, high spectral resolution is more difficult to achieve not only because of the increased heat capacity, but also because of problems with uniform thermalization. We have observed non-ideal effects in large absorbers that must be controlled and minimized before the fabrication of low noise, larger area microcalorimeters can be accomplished. © Plenum Publishing Corporation 1993 |
