This note came in from Director Totsuka to the press and other scientists. Hemos and I felt it deserved more than just a regular SlashBack reference, as we feel that this is an important project. (I belive this comes form a translation from japanese, so forgive the errors) this is an update to the original post on the Super-K malfunction.
As a director of the Kamioka Observatory, which owns and is responsible to operate and maintain the Super-Kamiokande detector, it is really sad that I have to announce the severe accident that occurred on November 12 and damaged the significant part of the detector. The cause and how to deal with the lo ss in future will be discussed by newly found committees. However, even before discussing with my colleagues of the Super-K and K2K collaborations, I have decided to express my intension on behalf of the staff of the Kamioka Observatory.
We will rebuild the detector. There is no question. The strategy may be the following two steps, which will be proposed and discussed by my colleagues.
1. Quick restart of the K2K experiment.
- (1) We will clear the safety measures which may be suggested by the committees.
- (2) reduce the number density of the photomultiplier tubes by about a half.
- (3) use the existing resources.
- (4) resume the K2K experiment as soon as possible; the goal may be within one year.
- (1) Restore the full Super-Kamiokande detector armed with the state-of-the-art techniques.
- (2) The detector will be ready by the time of the commissioning of the JHF machine.
