	GTCdigital - Gran Telescopio CANARIAS (Site not responding. Last check: 2007-10-23)
		The segments are 1.9 metres in diameter, 8 centimetres thick, weigh 470 kilos and are made of Zerodur™, a vitreous ceramic material extraordinarily uniform in composition that undergoes virtually no change as temperatures fluctuate.
		Grantecan selected Schott because of the German company’s leading position as a producer of optical glass products, vitreous ceramics like Zerodur™ and everyday materials like Ceran™, which is used in ceramic cooker hobs.
		Grantecan, the public company responsible for building the telescope, has specified an expansion coefficient of 0.050 microns / metre.

		The revised charge of our committee is to advise on the strategic situation of observational astronomy in Israel in the context of the proposal for participation in GranTeCan and to examine possible alternative ways of obtaining access to large optical/infrared telescopes for Israeli astronomers.
		CONSIDERATION OF OPTIONS Although the Committee was presented with a single option for the provision of large telescope access (namely a share in the GranTeCan telescope at present near completion in the Canary Islands), it is helpful to contrast the merits of this option against alternatives.
		The GranTeCan (GTC) is a 10 meter segmented mirror telescope being constructed on the Canary Island of La Palma (Spain).

		The latest generation of giant telescopes is going to expand the size of the known universe by an order of magnitude.
		To succeed in this task, enormous structures such as teh Gran Telescope of Canarias (GranTeCan) which are 30 mt tall, 20 mt wide and with mass in the several hundred tons, need to be controlled in position and speed with submicron accuracy, responding in real time to large random perturntions such as wind buffeting.
		The experience acqured in the control of large, flexible structures with direct drives shows large direct drive to be a very viable, cost competitive and super performing approach which will likely supersed large rack and pinion, bbogie or friction drives un multimeter diameter position control.

		In the short to medium term, the Spanish 10-m GranTeCan, a Keck-type telescope currently under construction, offers the potential for collaboration and ultimately for the UK community to gain more access to large telescopes in the northern hemisphere.
		Participation in GranTeCan would also allow the UK astronomers and engineers to gain valuable hands-on experience in segmented mirror technology and position the UK well for future development of any Extremely Large Telescope.
		The development of the La Palma observatory in a European context is currently being discussed at various levels: - A joint European operation of medium sized telescopes may well emerge as the future umbrella required to retain the INT and JKT.

		Now it seems that the crowd is growing with the new 'muchachos' like GRANTECAN, MAGIC and the Liverpool Telescope.
		GRANTECAN is currently in the process of constructing the dome as illustrated in the accompanying pictures.

		Until very recently he worked for Grantecan, the company building the GTC, but now he is going home to Ireland.
		Nicholas studied experimental physics at the University of Galway, where he developed proposals for a technique to improve the spatial resolution of astronomic images.
		I was responsible for Grantecan's work with the European network of Adaptive Optics for the Extremely Large Telescopes (ELT).

	OSIRIS - Introduction
		OSIRIS represents a new generation of instrumental observing techniques, that includes the concepts of tunable filters (TF) and charge shuffling on the CCD detectors.
		On October 23-24, 1997, a Spanish National Meeting organised by GRANTECAN was held in La Laguna to identify the interests of the spanish community for the GTC instruments.
		In July 29 1999 a contract was signed between the IAC and GRANTECAN for a preliminary design.

		of March 1994 called the Gran Telescopio de Canarias, S.A. (known as GRANTECAN.) This non-profit making organisation was created with the aim of providing the IAC with the necessary resources to develop the large telescope project.
		The initial design of this large telescope, similar to other designs of the eighties, was based on a primary monolithic mirror of 8 metres.
		These sensors needed to enable the perfect alignment of all 36 mirrors so that the optical characteristics achieved were equivalent to those of a monolithic mirror of 10 metres.

	ING and GranTeCan
		Within the next few months groundwork will commence in preparation for a new telescope that will become the centrepiece of the facilities at the observatory on La Palma.
		The new facility under construction is the Gran Telescopio de Canarias, also known as GranTeCan, or simply GTC.
		GTC is a segmented 10-m aperture telescope based on the Keck telescope design.

		SCHOTT is supplying 42 "Zerodur" glass ceramic mirror carriers for the project.
		The manufacture of mirror segments for telescopes like the Grantecan calls for close cooperation between production and measuring technology.
		A cooperation agreement between SCHOTT and the Chinese television glass manufacturer ACBC allows the partners to react to the growing demand for large format sets in China.
