Opticon Porto 2
special thanks to
Don Phelan, NUI, Galway taking over network administration coordinating
the two workshops editing the two volumes of proceedings annual meetings
Opticon Porto 3
Background - rationale for the network Are there special HTRA requirements?
detectors high quantum efficiency photon counting low (zero?) read-out noise APDs, EMCCD, PNCCDs, Transition Edge Sensors,
superconducting tunnel diodes wide wavelength range UV-IR
instruments spectroscopy : Ultraspec photometry : Ultracam, Optima, S-CAM polarimetry : Optima, GASP very short time scales (t < 10-7 s): Quanteye, GASP

Future plans under FP7
Continuation of the network building upon our work under FP6 .... with the aim of formulating a comprehensive scientific
overview of HTRA into the extremely large telescopes [ELT] era......
primarily looking at HTRA science and instrument requirements
