  10. - 8 strings • 192 optische Module • Zeuthen: • 2 N2-Laser • DAQ in Uferstation • Div. Elektronik • Ersatzteil-Käufe • Finanz-Unterstützung

  11. BED Wasserdicht: ~ 900 Stecker ohne Leck !!!

  12. Eines der ersten Neutrino-Ereignisse, die mit dem Baikal-Teleskop registiert wurden. (1996)

  13. NT-200 NT-200 140 m cascades Upgrade: NT-200+ 36 zusätzliche PMTs  4x besser Sensitivität !

  14. A lesson on electro-corrosion + -  40m  unexpected electro-corrosion after > 6 years

  15. points of problems + - Two out of four cables have broken during installation works in Spring 2003. Detector runs only with 5 strings in 2003. Two new cables in March 2004.
