Ninety-eight students coming from twenty-five different countries attended the fourteenth in the new series of the European School of High-Energy Physics, which took place in Aronsborg, from 18 June to 1 July 2006.

The School was hosted in Aronsborg Konferenshotell, a nice four star hotel located by the Lake Mälaren, the largest lake in Sweden. The School participants profited from the outdoor installations like a football field and tennis courts. It was also possible to borrow bicycles and canoes, and there were many possibilities for nice walks along the lake or in the forest surrounding the hotel or to the nearby town, Balsta. Inside the Hotel one could use the swimming pool, the billiards, the darts, the piano and not to forget the attractive nightclub.

Midsummer Night Dancing Around the May Pole

Short History.

Aronsborg is 2 km away from the center of the closest town, Balsta. There are many nice houses and summer residences along the shores of Lake Mälaren, a fascinating destination in Sweden. Due to its attractive situation there are several medieval castles built in this area, and in Sigtuna, a little town 30 km away from Aronsborg and dating back to around 980 AD, one can find more rune stones than in any other town in the world.


The School

The School was hosted in Hotel Aronsborg, a modern style hotel, 100 meters from the Lake Mälaren. According to the tradition of the School, the students were sharing twin rooms, mixing nationalities and in particular Eastern students with Western ones.
All the meals were buffet style. However, on Friday 23 June a special Swedish "smörgåsbord" was prepared to celebrate the “midsummer night”. For the farewell banquet, several guests had been invited to a special "served" dinner accompanied by wine and beer.

The lectures were held in a large conference room located on the ground Floor. Tea, coffee and cookies were served in a nice area just in front the lecture hall, and smaller rooms were used for the discussion sessions.

At 5.00 p.m. after the free time the participants reconvened for the third lecture of the day. This was followed by a coffee break and preparation for the Discussion Session lasting until dinner. The after dinner sessions were organized by the students themselves, and many gathered happily and danced in the hotel nightclub where the bar was very popular not the least due to it's large screen were some of the most interesting World Cup soccer matches were shown.

Tatyana and Danielle were omnipresent in the School Secretariat located close to the lecture room, and where also Barbara, who visited the hotel on behalf of the CERN Accelerator School, joined and helped them for a week.

 The Poster Session
The students displayed their work in the form of posters at a special evening session during the first week. The posters, of very high quality both technically and in content, were put up on the walls of the lecture room and on display panels in the lobby where they stayed on display for the remaining part of the school.

Excursions and Special Events were organized during the school.
The first Monday, a welcome drink was offered by the Natural Science Faculty of Uppsala University and the Municipality of Balsta and welcome speeches were given by Professor Ulf Danielsson, Dean at the Science Faculty and by Leif Zetterberg representing the Municipality.

The first Wednesday afternoon was a guided tour of Uppsala, hosting the oldest University in Scandinavia (founded in 1477). The tour included a visit to the Cathederal, constructed in the period 1287 to 1435. The Gothic style cathedral is one of the largest in northern Europe, with towers reaching 118 metres. (See A number of Swedish kings and personalities are buried inside the Cathederal, among others, Gustav Vasa, 16th century, mighty King of Sweden and his two wives, and Carolus Linnaeus, 18th century, world renowned botanist
Unforunately the guided tour of the Linnaeus´ Garden was perturbed by rain. This garden is a reconstruction of the Uppsala University Botanical Garden the way it looked during Linnaeus´ days. In fact, in 1741, Carl Linnaeus was appointed professor of medicine and became responsible for the garden. The garden played an essential role for Linnaeus as scientist and teacher. This is where he made scientific observations and taught his students. Each part of the garden reflects his ideas, and each plant was carefully chosen to serve an educational purpose. Throughout the garden, the Linnaeus´ sexual system is illustrated as well as his interest in phenology (the seasonal and daily changes in nature) and the use of indigenous and exotic plants in medicine and dietetics. The garden is a living complement to his writings. (See: and ).
The visit was especially profitable since it followed an interesting lecture given by Mariette Manktelow two days before about the sexual system of plants and the classification system introduced by Carl Linnaeus.

MIDSUMMER, day and night!
Friday, 23 June was the traditional Swedish MIDSUMMER NIGHT, a very popular day with special events all over the country. The lectures had been re-schedule so that it was possible to attend the ceremony of “Raising the Balsta May Pole”. The School participants left the hotel around 11:00 a.m. for a green in Balsta where the “May Pole” was erected, with active participation of the students under the command of Tord Ekelof, the Local Director.

The Boss

Folk musicians dressed in traditional costumes were playing typical Swedish music and a nice old lady acted as Master of Ceremony, instructing children and unitiated school participants how to dance and perform around a May Pole.

Back at the hotel a special traditional Swedish lunch had been prepared, and after lunch another May Pole was raised in front in the hotel park again followed by dancing, songs and a special popular game called Kubb until it was time to go to the last lecture of the day.

The special Midsummer Night "Smörgåsbord" dinner was accompanied by Swedish snaps tasting together with traditional Swedish songs led by the two excellent performers, Leiv Lönnblad and Tord Ekelöf. A local musician, Roger Andersson, had been specially invited to play folk music on a special instrument called nyckelharpa.

Saturday was a visit to Stockholm. On the way the buses stopped in Fjällgatan, a place with a beautiful view of Stockholm, the fjord and the end of Lake Mälaren.

Undoubtedly, Stockholm is one of the world’s most beautiful capitals. Built on 14 islands, it is surrounded by water so clean that it is possible to swim and fish everywhere.

Stockholm - Beauty on the Water

The tour started with a visit to the Wasa Museum, housing the warship “Wasa” which sank in Stockholm harbour on its maiden voyage in 1628 and was brought to the surface again in 1961. The “Wasa” was located on the seabed in 1956 at a depth of 32 m, and work began three years later on recovering and preserving it. This was a large-scale operation for which entirely new techniques had to be devised.
The vessel, 62m long, is the only completely preserved 17th century ship in the world, and it is displayed together with numerous objects and carved ornaments recovered from the vessel.
The Wasa Museum, a modern building crowned by three masts and inaugurated in 1990, contains cinemas, computer rooms, replicated captain’s quarters and sailors’ cabins, a cannon deck, a restaurant and a shop and is well worth the visit even for people with no interest in maritime history.
In the afternoon people visited Stockholm on their own, and the Old Town was a particularly popular destination. This quarter of the city has an eventful history, and has been known as a place of sin, of executions, but also for grandiose royal weddings. To walk through the alleys of the Old Town is like walking down a history lane!
At the end of the day a few people stayed in Stockholm in order to watch an important World Cup soccer match on huge screens in different places in town, and had to come back by their own means late that night.
Many of the School participants took advantage of the free time on the afternoon of the second Wednesday, to visit Sigtuna, about 30 km from Aronsborg. Sigtuna is the oldest living town in Sweden, and one of the most picturesque. The town, which dates back to around 980 AD, has a medieval street plan, 12th and 13th Century ruins, and ten runic monuments within the town center

On the last evening the traditional Farewell Banquet, was celebrated in the dining room which had been specially set up for the event, and various delicious dishes were served. Informal speeches were given by our special guests, Alexei Sissakian, Cecilia Jarlskog, Sven Kullander and Per Olof Hulth.
The traditional after dinner seremony had to be made very short - again due to a very important World Cup soccer match, but Egil managed to keep everybody together to express our special thanks to the local staff of the hotel who had helped making the two weeks so pleasant. The Hotel team highly deserved a big applause and was offered nice souvenirs. Also a few particularly "deserving" students were congratulated for their extra scholary activities and offered small prices from JINR and CERN.
Later on most of the participants gathered close to the nightclub where the students were singing traditional national songs and accompanied by Egil on the piano whenever he managed to follow. Two of the students also played together in "four hands".

The "ceremony" was ended by Selma singing a special song, “you quark me up”, composed for the occasion and accompanied by Gernot. The song text is reproduced below.


We are sure that all the students join us in thanking the lecturers and discussion leaders for their inspiring lectures and discussions, and the organizers also thank the students for their eager and positive participation in all the school activities.
