The potential degradation of spectral resolution in Solar-B EIS CCDs
نویسندگان
چکیده
One of the main drivers for determining the operating temperature of the Solar-B EIS CCDs is the possibility that substantial Charge Transfer Inefficiency may occur towards the end of the mission lifetime. The magnitude of the CTI has been discussed in several technical notes (references 1-3) and this information has been used to judge the optimum and minimum operating temperature of the CCD (reference 4). Using spectral lines generated using CHIANTI, it will be shown that one of the main effects of CTI will be that the velocity resolution achievable for faint spectral lines could be reduced if the operating temperature of the CCD is too high.

Technical guide to Set Up a Spectral Solar Direct Normal Irradiance Permanent Station: Study Area- Hannover, Germany
The spectral Direct Normal Irradiance (SDNI) is a basic radiometric quantity from which many other quantities can be derived. It provides not only information about the spectral and distribution of the direct solar radiation reaching a particular location. Accurate knowledge about the spectral direct irradiance shall enable us to gain new scientific results in the: determination of cloud effect...
متن کاملThe calculation of total dose using SPENVIS
The potential radiation dose for the Solar-B EIS CCDs was discussed in reference [1], and the potential effect of that radiation dose was discussed in reference [2]. Whilst the effect of ionising radiation on CCD areas such as flat band voltage shifts was not a cause for concern (although the transient effects on image quality may be) there was a potential problem with the effect of Non-Ionisin...

This thesis has two distinct components. One concerns the physics of the high energy resolution X-ray Charge Coupled Devices (CCD) detectors used to measure the cosmic Xray background (XRB) spectrum. The other involves the measurements and analysis of the XRB spectrum and instrumental background with these detectors on board the Advanced Satellite for Cosmology and Astrophysics (ASCA). The XRB ...
