Aachen in the Limelight The Compact Muon Solenoid Experiment CERN,CH–1211, GENEVA 23, Switzerland Date of publication: 06-09-96 Number 96-01 CMS internal information servers: http://cmsdoc.cern.ch/cms.html and ftp://cmsdoc.cern.ch Aachen in the Limelight A prototype of the muon chambers for the CMS experiment, built at the RWTH Aachen, placed in the H2 muon test beam at CERN last July. For many of us our journey with CMS started in The prototype has dimensions of 3x1 m2 and is the earnest in Aachen. The event signalling the start was barrel muon drift chamber consisting of 12 layers of the ECFA sponsored "Large Hadron Collider drift cells. For the Barrel Muon Detector groups Workshop" during 4-9 October 1990. The workshop from Aachen, Bologna, Madrid and Padova have was highly successful and led to the adoption of the already tested several drift chamber prototypes of LHC as the next accelerator for CERN. Then the different sizes and arrangements in muon and chairman of ECFA was Jean-Eudes Augustin and hadron beams at CERN. Although extensive studies the chairman of the Organizing Committee was have been carried out up to now, an essential test is Günther Flügge both of whom are in CMS. We can still missing. At the LHC, the muon chambers will really say that "the LHC ball started rolling in be exposed to a sustained and high rate of particles Aachen". Almost six years later we are back in over their full area. Presently there is no such beam Aachen, this time for the CMS Week. Now we can at CERN. An installation consisting of a muon test say that CMS is changing gear as the first full-scale beam and a high activity radioactive gamma source, prototype, illustrated above, of a CMS detector has that simulates the conditions at the LHC, has recently been completed and transported to CERN recently been approved by CERN. This "Muon Test for beam tests. Here again Aachen takes the Facility" will be available in spring 1997 for testing limelight as this prototype has been constructed in prototypes of muon detectors. the workshops of RWTH Aachen. EDITOR-IN-CHIEF OF THE CMS BULLETIN I am happy to announce that Felicitas Pauss has accepted to be the Editor-in-Chief of the CMS Bulletin. She has been one of the strongest proponents of such a bulletin. Michel Della Negra Competition What should be the CMS logo? You will have seen the cover page of this bulletin - you should now look again and decide if you would like to keep this “CMS-cube-logo” or propose something better. Remember, this logo will stay with us for many years and will also be used for other purposes! You are therefore invited to participate in a “logo-competition”. Please send your proposal to the Editor-in-Chief of the Bulletin (Felicitas Pauss) before the 15th of November 1996. During the CMS week in December the Collaboration Board will choose the logo by voting. The person proposing the selected logo will receive a special award to be announced in the next bulletin. EDITORIAL Why should there be a Bulletin? In spite of the vast amount of information dispersed in various media, like for instance on the Web, it is important to periodically summarize the key facts and orientations of the scientific life of CMS. The most direct and practical way is a CMS Bulletin which will be available and distributed in printed form, as well as accessible on the Web. This general idea received strong support during the last CMS week, where it was proposed that the CMS Bulletin be issued after each CMS Collaboration week, i.e. four times a year. What should be the content of the Bulletin? - The Bulletin should contain a summary of the preceding CMS collaboration week, including concise status reports on different subdetectors. - Orientations which will condition the scientific future of CMS are mapped out in various bodies. There is also a quasi-permanent dialogue with the LHCC and related committees. These are usually presented orally to the Collaboration. The Bulletin will be the right platform where additional comments and explanations from the management can be added. - The Bulletin will also be an appropriate place for essays covering any specially interesting subjects. Suggestions and comments are very welcome! - CMS internal or external publications are numerous and cover a large spectrum of topics. A list of these publications ordered according to their classification will be provided together with the information on how to access them on the Web. - CMS life is rich in events and meetings, requiring therefore a good planing. The Bulletin will update agenda, underline the most important issues and can announce meetings well in advance. - CMS is a complex organization and the existing structure is not always sufficient to allow easy access to information necessary to find one’s way around, specially for newcomers and colleagues who make only infrequent visits to CERN. The information provided in the Bulletin should help improve this situation. How is all this organized? Motivated by the strong encouragement from the Collaboration Board, a first version has been prepared to be distributed during the CMS Aachen week. In order to improve on this first bulletin feedback from the Collaboration is essential. The next step will be to establish an editorial board. Everybody is invited to propose names to the Spokesperson. The Spokesperson and the Editor-in-Chief will select the members of the editorial board. This board will edit the bulletin, consider new suggestions and can also invite special contributions.

  • A Taxonomic Study of the Calcicolous Endolitic Species of the Genus Verrucaria (Ascomycotina, Verrucariales) with the Lid-Like and Radiately Opening Involucrellum
    A taxonomic study of the calcicolous endolitic species of the genus Verrucaria (Ascomycotina, Verrucariales) with the lid-like and radiately opening involucrellum. Josef Halda Muzeum a galerie Orlických hor, Jiráskova 2, 516 01 Rychnov n. Kn., [email protected] Abstract This study describes anatomy, ontogenesis and history of taxonomy of calcicolous endolitic species of the genus Verrucaria, which have been treated as Bagliettoa and Protobagliettoa (Verrucaria sect. Sphinctrina), and that are characterized by black, flat (lid-like) radiate crackling involucrellum, completely endolitic thallus and presence of macrosferoid cells formed by hy- phae in the lower part of the medullar layer. Most of the revised taxa were described by Servít (more than 100), and show a large taxo- nomic heterogeneity. Consequently, a detailed study had to be done to unify the group again. The characteristic characters have been recognized as the size and shape of the involucrellum and the development of the cortex layer. Following diacritic characters were recognized just morphological variations that originate regularly during ontogenesis. After revision the num- ber of species reducedfrom more than twenty to four: V. baldensis, V. limborioides, V. marmorea and V. parmigerella. The genus Bagliettoa differs from the genus Verrucaria in different forming of involucrellum, other significant characters (ascus morphology and further structures of hymenium), usually used to define lichen genera are identical. Therefore, a new section Bagliettoa has been estab- lished within the genus Verrucaria, which is well defined by the way of opening and shape of involucrellum. The genus Protobagliettoa has been separated from the genus Bagliettoa artifi- cially for the absence of ascospores in 1955 by Servít.

Kurzzusammenfassung Kurzzusammenfassung Die vorliegende Arbeit soll dem Leser die über 200 jährige Erforschungsgeschichte der Eifelgeologie näher bringen, bei der auch die Zusammenhänge von der Entwicklung einer Natur- zu einer Kulturlandschaft verdeutlicht werden. Es wird ein Bogen zwischen der historischen und der wissenschaftlichen Erforschungsgeschichte der Geologie für einen regional begrenzten Raum, die Eifel, gespannt. Schwerpunktmäßig ist die Darstellung auf die Anfänge der Erforschung und die wichtigsten klassischen Fakten aus der Eifelregion begrenzt. Dem Leser wird die Vorgeschichte des heutigen Wissenstands und ein Einblick in die lange Erforschung dieser Landschaft vermittelt, die gebietsweise in Zusammenhang mit den bergbaulichen Tätigkeiten steht.
