	Braunschweig - Wikipedia, the free encyclopedia
		Tradition maintains that Braunschweig was created through the merger of two settlements, one founded by Bruno II, a Saxon count who died before 1017 on one side of the river Oker and the other the settlement of Count Dankward, after whom the still surviving Castle is named.
		Braunschweig was a member of the Hanseatic League from the 13th century to the middle of the 17th century.
		Braunschweig was a duchy until 1918, and afterwards a state within the Weimar Republic.

	ILT - PTB Braunschweig
		" The Physikalisch-Technische Bundesanstalt (PTB) in Braunschweig and Berlin is the national institute for science and technology and the highest technical authority of the Federal Republic of Gerrnany for the field of metrology and certain sectors of safety engineering.
		It is the most important task of the PTB to realize and maintain the legal units in compliance with the International System of Units (Sl) and to disseminate them, above all within the framework of legal and industrial metrology.
		The PTB accomplishes its task in accordance with the provisions of public law.

	atomic clock - radio clock
		In Germany the transmitted frequencies and signals are derived from the atomic clocks of the Physikalisch-Technische Bundesanstalt (PTB) Germany, the national institute for science and technology and the highest technical authority of the Federal Republic of Germany concerning metrology and physical safety engineering in Germany.
		The control signal is not transmitted from Braunschweig via lines, as is often assumed, but is generated in situ with the aid of a control device designed by PTB and monitored from Braunschweig.
		After the DCF77 signal generated by the PTB facilities has been conducted to T-Systems Media Broadcast, this company is responsible for emitting it via the transmitting and antenna facility operated by it.

		When the solvent is intended for a use on web offset presses with heat-set dryer, an additional examination of the solvent must be made by the "Physikalisch-Technische Bundesanstalt" in Braunschweig (PTB; Physical-Technical Federal Agency).
		In a test, the data of the lower explosion limit (LEL at 20° Celsius and 1013 mbar) and the response factor (mass-specific conversion factor) for the measuring instruments calibrated to propane are determined.
		We expressly point out that in the case of damage (explosion in the dryer), the PTB will examine the solvent.

	ISS - Medphys Digital radiography
		We are trying to optimize X-ray systems in terms of detector quantities, for which we will provide the possibility of a transportable, highly accurate measurement facility and in terms of optimal beam qualities depending on the detector characteristics and on the imaging geometry.
		The exemplary measured values for some systems (performed so far mainly by PTB, Braunschweig, Germany and the University of Magdeburg, Germany) are shown in figure R1.
		For these optimisation processes we are also using the knowledge from our voxel phantoms and investigations with high resolution imaging used in combination with real human specimens (lung and breast — see images R2a and R2b).

	Characterisations of Deuterium lamps as transfer standards for a comparison of spectral irradiance (Site not responding. Last check: 2007-10-22)
		The Physikalisch-Technische Bundesanstalt (PTB) in Braunschweig, Germany acts as the pilot laboratory for the comparison CCPR-K1.b.
		This sub-comparison of the CCPR key comparison K1 of spectral irradiance covering the wavelength range from 200 nm to 400 nm shall be carried out in 2002/03.
		Based on former experience in the PTB, the new facility has several specific features: in a conventional spectroradiometer the optical UV-signal is very much reduced by reflection losses at a number of mirrors (typically Al-mirrors).

		As for the realisation of the UV spectral responsivity scale, substantial progress was made in the past few years by using cryogenic radiometers as primary detector standards, operated with tuneable UV lasers or spectrally dispersed radiation from incandescent lamps or synchrotron radiation (SR) sources, respectively.
		The results of the two calibrations show a satisfactory agreement within the combined uncertainties, which is an important improvement as compared to the outcome of the international comparison of spectral responsivity some years ago [2].
		The first WG 2 meeting during the second workshop in Braunschweig (November 1998) focused on scope and delimitation of WG 2 work, the discussion of the feedback on the first questionnaire and the identification of measurement problems.
