Part ‘a’ of this course is aimed at observational astronomers in general, to provide a solid basis on the generation of their data.
Detectors are the crucial link between the astronomical target and the observer. Apart from the telescope, their performance is arguably the single most important component – and often weakest link – in the chain of observational devices. As astronomers are aiming at fainter and fainter targets, the quality and calibration of the detector systems have become increasingly important.
Topics to be covered include intrinsic and extrinsic photo-conductors, CCDs, infrared arrays, photodiodes, bolometers, and submillimeter- and millimeterwave heterodyne receivers. In addition, this course covers practical aspects which are of general interest to the observer, such as cosmetic quality, linearity and dynamical range, spectral response and bandwidth, and quantum efficiency and noise.
Part ‘b’ of this course will focus on very recent detector technologies, such as microwave kinetic inductance detectors (MKIDs), transition edge sensors (TES), electron multiplying (EM) CCDs, avalanche photodiodes, and more. Some lectures will be given by guest lecturers. This part is also complemented by practical exercises.
The main objectives of this course are to provide an overview of:
- the various technologies (and underlying physics) used to detect UV to the sub-millimeter radiation;
- the most common devices to be found at an observatory;
- performance aspects and artifacts of detectors;
- readout and calibration strategies for detectors;
- overview of future detector technologies for astronomy.
