CCD Lab Calibration Instruments


QE Chamber

The QE chamber allows the user to measure the quantum efficiency of CCID-17 devices. The chamber provides a steady flux of X-rays incident on two CCDs, which lie on a translation stage. Thus, one test CCD can be cross-calibrated against a reference CCD.

HIREFS

This is a grating spectrometer which operates in the low energy X-ray band, from 250 eV and up to approximately 2.5 keV. Allows to measure the energy resolution and the linearity of the CCD response in the specified range. Also makes it possible to detect a near-edge absorption structure in the CCD response around the Oxigen K absorption edge.

IFM Detector

The In-Focus Monochrometer is based on a new grazing incidence focusing condition. New technologies allow a new degree of freedom and it eliminates defocsig at every wavelength, gives symmetrical line shapes, and provides a physically compact instrument.

Si(Li) Detector

As part of the calibration instrumentation used to test and characterized CCD's for the ACIS system, MIT is using a solid state spectrometer (SSS) as a reference detector for quantum efficiency measurements in the range from 3 keV to 10+ keV. The detector is a lithium-drifted silicon crystal, or "Si(Li)" detector, manufactured by Princeton Gamma Tech, Inc. (PGT).

X.C.C.M.

This is the most important equipment in our lab. Without this, no one can operate at best condition.
