International Workshop on


Neutrino Masses in the sub-eV Range

and future high precision tritium experiments


Bad Liebenzell/Schwarzwald, Germany, January 18 - 21, 2001

Second Circular

Dear Colleagues,

this circular is the last one before the upcoming workshop which will be held in

Burg Liebenzell, Germany, January 18 - 21, 2001.

Any further information will be given on our webpage. Please check the webpage regularly before you leave to Burg Liebenzell.

This workshop is planned to discuss the future perspectives of direct mass measurements and to address the implications of next-generation experiments for particle physics, astrophysics and cosmology.

Scientific Programme:

The neutrino mass workshop at Bad Liebenzell will consist of 10 plenary sessions covering the following topics :

• the physics and techniques of the current and next generation direct neutrino mass measurements
• the implications of high sensitivity direct neutrino mass measurements for models of neutrino masses and mixings, as well as for astrophysics and cosmolology
• the perspectives and implications of alternative measurements such as direct mass measurements with cryogenic detectors, double beta-decay searches, cosmic microwave experiments and galaxy surveys
• our current understanding of the shape of the Tritium beta-spectrum
• high precision electron spectroscopy and new physics
• the application of the magnetic adiabatic collimation technique in other areas of particle and nuclear physics

See also the workshop schedule and the preliminary programme.

Organization:

The workshop will consist of two and a half days of invited plenary talks covering all topics mentioned above (Friday, January, 19 to Sunday, January, 21). The regular programme will start on Friday morning, January 19, 2001 at 08:30 and will end on Sunday, January, 21, after lunch.

Therefore, all participants are expected to arrive at Burg Liebenzell on the early afternoon of January 18, and stay until January 21 after lunch.

In addition to the 50+ people lecture hall for the plenary sessions the castle offers smaller rooms for group meetings in the afternoons or evenings.

Before the regular workshop on January 19, 2001, there will be a one day pre-workshop (January 18th) on technical questions of a next-generation direct neutrino mass measurement. Please notify the organizers if you wish to participate in the pre-workshop.

Workshop summary:

The organizers plan to write up a summary report of the results of the workshop which will be distributed to the participants and be made available to the broader community.

The transparencies of all talks will be made available electronically on the web after the workshop together with the e-mail address of the author for further communication. To enable this, please bring high quality paper copies of your transparencies with you. Of course, if your material is available in electronic form, this is naturally prefered.

Technical equipment and contacts:

In the lecture hall, overhead transparencies as well as slides can be used. In addition we will provide a beamer system for presentations and a video system (VHS) for speakers who want to show a movie. If you intend to use a beamer/video please contact the organizers under Liebenzell@bk.fzk.de. For more traditional presenters a blackboard + chalk and also paper flipcharts are available.

Most other technical resources are limited. Copies can be made in small quantities only. Internet and email connections with limited capacities will be provided. Details will be given at the start of the workshop.

Participants can be contacted via the address info@InternationalesForum.de, if necessary.

Venue and Transport:

"Burg Liebenzell" is a medieval castle situated on a hill (450m above sea level) next to the small town of Bad Liebenzell in the northern part of the Black Forest - about 180 km south of Frankfurt, 50 km south-east of Karlsruhe and 40 km west of Stuttgart.

International flights may best be booked to Frankfurt.

The railway station (Frankfurt(M)Flughafen) at the airport ("Fernbahnhof") has frequent connections to Karlsruhe, from there you can continue to Pforzheim and Bad Liebenzell. Train connections Frankfurt Airport to Bad Liebenzell are served every 60 minutes (9:56, 10:56, ... 17:56, 18:56) and usually arrive after a total travel time of 2:20 at Bad Liebenzell station at (12:16, 13:16, ... 20:16, 21:04). You have to change trains at Karlsruhe Hbf and Pforzheim Hbf. For details see the internet railway information http://bahn.hafas.de/bin/query.exe/en.
Also, the Stuttgart airport offers frequent train connections to Bad Liebenzell via Stuttgart main station and Pforzheim.
Please let us know (until January, 15th) when you will arrive at Bad Liebenzell station. You will be picked up by a free shuttle bus and directly transferred to the castle (transfer time about 15 min).
For your departure, please let us know your travel schedule as well.

For those who plan to come by car: Bad Liebenzell is situated 20 km south of Pforzheim which is right on the Autobahn A8 between Karlsruhe and Stuttgart. At Pforzheim follow the road B463 which leads to Bad Liebenzell, Calw and Nagold. At Bad Liebenzell a small road leads to the castle Burg Liebenzell, which is to the west just above the town. Please keep in mind that the workshop is in mid-January and road conditions might be difficult due to ice and snow.

Arrival:

Participants arriving on Thursday afternoon (18th) will get their room keys at the conference secretariat (Frau Grundel) located at the entrance to the castle ('Jagdstube'), and will be welcomed by a small buffet.

Accommodation:

Burg Liebenzell is an international conference center which has housed more than 90.000 people from 120 nations. It will accommodate the workshop participants in single rooms. Several rooms share common showers on the corridors. We aim to house all participants at the castle, however some hotel rooms are available in the town of Bad Liebenzell at additional costs.
Participants staying at the castle will have full board which will be served in the dining hall (breakfast from 7:30 to 8:30, lunch from 12:30 to 14:30 and dinner at 18:30. In addition coffee will be served during the breaks.

Tourist and Weather Information:

Burg Liebenzell was built by the Counts of Eberstein at the beginning of the 12. century. It is situated at an altitude of 450 m in the middle of a forest with a nice view into the valley and down to Bad Liebenzell, which is in abou t 20 minutes walking distance. There is plenty of opportunity for walking and hiking in the immediate vicinity. Be sure to bring appropriate shoes. In addition to the lecture hall and study group rooms at the castle there is a table tennis room (bring your equipment) and a beer and wine cellar for evening meetings. Bad Liebenzell offers many possibilities for swimming (including a famous thermal spa and sauna world), tennis, squash, horse riding, golf, fishing, and many other sports. Train connections e.g. to Heidelberg or Baden-Baden are frequent and take less that 2 hours.

The weather in this part of Germany can be rather cold in mid-January with day temperatures ranging from -10C to +10C. Snowfall may occur, so be prepared!

For open questions, problems, proposals, etc. feel free to contact Liebenzell@bk.fzk.de or one of the organizers.
Looking forward to seeing you soon at the castle,
