Anthony van Dyck

Sir Anthony van Dyck was a Flemish Baroque artist who became the leading court painter in England after success in the Southern Netherlands and Italy. The seventh child of Frans van Dyck, a wealthy Antwerp silk merchant, Anthony was precocious as a youth and painted from an early age. In his late teens he was enjoying success as an independent painter, becoming a master in the Antwerp guild in 1618. By this time he was working in the studio of the leading northern painter of the day, Peter Paul Rubens, who became a major influence on his work. Van Dyck worked in London for some months in 1621 returned to Flanders for a brief time, before travelling to Italy, where he stayed until 1627 based in Genoa. In the late 1620s he completed his admired Iconography series of portrait etchings of other artists, he spent five years after his return from Italy in Flanders, from 1630 was court painter for the archduchess Isabella, Habsburg Governor of Flanders. In 1632 he returned to London to be the main court painter, at the request of Charles I of England.

With the exception of Holbein, van Dyck and his contemporary Diego Velázquez were the first painters of pre-eminent talent to work as court portraitists, revolutionising the genre. He is best known for his portraits of European aristocracy, most notably Charles I and his family and associates. Van Dyck became the dominant influence on English portrait-painting for the next 150 years, he painted mythological and biblical subjects, including altarpieces, displayed outstanding facility as a draughtsman, was an important innovator in watercolour and etching. His superb brushwork rather painted, can be distinguished from the large areas painted by his many assistants, his portrait style changed between the different countries he worked in, culminating in the relaxed elegance of his last English period. His influence extends into the modern period; the Van Dyke beard is named after him. During his lifetime, Charles I granted him a knighthood, he was buried in St Paul's Cathedral, an indication of his standing at the time of his death.

Antoon van Dyck was born to prosperous parents in Antwerp. His father was Frans van Dyck, a silk merchant, his mother was Maria, daughter of Dirk Cupers and Catharina Conincx, he was baptised on 23 March 1599. His talent was evident early, he was studying painting with Hendrick van Balen by 1609, became an independent painter around 1615, setting up a workshop with his younger friend Jan Brueghel the Younger. By the age of fifteen he was a accomplished artist, as his Self-portrait, 1613–14, shows, he was admitted to the Antwerp painters' Guild of Saint Luke as a free master by February 1618. Within a few years he was to be the chief assistant to the dominant master of Antwerp, the whole of Northern Europe, Peter Paul Rubens, who made much use of sub-contracted artists as well as his own large workshop, his influence on the young artist was immense. Rubens referred to the nineteen-year-old van Dyck as "the best of my pupils"; the origins and exact nature of their relationship are unclear. It has been speculated that van Dyck was a pupil of Rubens from about 1613, as his early work shows little trace of van Balen's style, but there is no clear evidence for this.

At the same time the dominance of Rubens in the small and declining city of Antwerp explains why, despite his periodic returns to the city, van Dyck spent most of his career abroad. In 1620, in Rubens's contract for the major commission for the ceiling of the Carolus Borromeuskerk, the Jesuit church at Antwerp, van Dyck is specified as one of the "discipelen", to execute the paintings to Rubens' designs. Unlike van Dyck, Rubens worked for most of the courts of Europe, but avoided exclusive attachment to any of them. In 1620, at the instigation of George Villiers, Marquess of Buckingham, van Dyck went to England for the first time where he worked for King James I of England, receiving £100, it was in London in the collection of the Earl of Arundel that he first saw the work of Titian, whose use of colour and subtle modeling of form would prove transformational, offering a new stylistic language that would enrich the compositional lessons learned from Rubens. After about four months, he returned to Flanders, but left in late 1621 for Italy, where he remained for six years.

There he studied the Italian masters while starting his career as a successful portraitist. He was presenting himself as a figure of consequence, annoying the rather bohemian Northern artist's colony in Rome, says Giovan Pietro Bellori, by appearing with "the pomp of Zeuxis... his behaviour was that of a nobleman rather than an ordinary person, he shone in rich garments. Since he was accustomed in the circle of Rubens to noblemen, being of elevated mind, anxious to make himself distinguished, he therefore wore—as well as silks—a hat with feathers and brooches, gold chains across his chest, was accompanied by servants." He was based in Genoa, although he travelled extensively to other cities, stayed for some time in Palermo in Sicily. For the Genoese aristocracy in a final flush of prosperity, he developed a full-length portrait style, drawing on Veronese and Titian as well as Rubens' style from his own period in Genoa, where tall but graceful figures look down on the viewer with great hauteur.

In 1627, he went back to Antwerp where he remained for five years, painting more affable portraits which still made his Flemish patrons look as stylish as possible. A life-size group portrait of twenty-four City Council

ASTRID

ASTRID is a particle storage ring at the Department of Physics and Astronomy of Aarhus University. ASTRID was designed, constructed and is operated by the Institute for Storage Ring Facilities in Aarhus. Designs for ASTRID started in 1985; the original concept for the ring was to store low-energy heavy ions for laser spectroscopic and laser cooling experiments and for atomic collision studies. It was soon realised during the design phase that it would be possible to store energetic electron beams in the ring and therefore ASTRID could operate as a synchrotron radiation source, providing photons in the UV to soft x-ray region. In 1988 the Natural Sciences Faculty at Aarhus University was awarded 16.7 M DKK for establishing an Instrument centre in Synchrotron Radiation Research, thus forming ISA. By late 1989 ASTRID was operating in ion storage mode with the first experiments being carried out on laser cooling a stored beam of Li+ ions to 1 mK. Electrons were first stored in ASTRID in 1991 and by this time two beamlines had been constructed to make use of the synchrotron light, a surface science beamline and an x-ray microscope.

Ion storage in ASTRID dominated in the early 90s, with many successful experiments storing both positive and negative ions ranging in mass from 1 to 840. Meanwhile, the synchrotron radiation based research at ISA was expanding, by 1995 ASTRID was operated 50% of the time in ion storage mode and 50% for synchrotron radiation. With the construction of the Electrostatic Storage Ring for Ions in 1998, an increasing demand for synchrotron radiation, the ion storage runs were reduced, until in 2005 ASTRID operated in ion storage mode for the last time. Since ASTRID has been operating in electron storage mode producing synchrotron radiation throughout the year, with 3 or 4 electron runs, separated by shutdown periods for maintenance and development of the ring. In December 2008, a contract was awarded to design and build ASTRID2, a 46-meter storage ring which will be built adjacent to ASTRID. Rather than having an electron beam which decays over time, ASTRID2 will be continually "topped up" by a feed from ASTRID, allowing nearly constant current.

It is expected to be completed by the end of 2011. It will generate synchrotron radiation to provide a tunable beam of light, expected to be of "remarkable" quality, with wavelengths from the ultraviolet through to soft x-rays; the ASTRID storage “ring”, with a circumference of only 40 m, is a square, formed by four sets of two 45 degree dipole bending magnets. There are eight pairs of quadrupole magnets used for horizontal and vertical focusing of the electrons and eight pairs of sextupole magnets for chromaticity correction. Electrons are injected via a septum magnet into the ring from a 100 MeV race-track microtron in 4-5 mA pulses, captured by a 105 MHz RF system which bunches and accelerates the electrons as they pass through the RF cavity. Many of these pulses of electrons are accumulated at 100 MeV to reach more than 180 mA of current in the ring, accelerated to 580 MeV with negligible loss of beam; the lifetime of a stored beam at 160 mA is 100 to 120 hours. The table below shows the typical operating parameters for ASTRID when running in electron storage mode.

There are eight operational SR beamlines on ASTRID. The characteristics of these beamlines are summarised in the table below and their location shown in the schematic drawing. Please follow the links in the table for further information and descriptions of the individual beamlines.
