H Hirano,M. Akatsu,Y. Fujita,K. Fujimoto,M. Hirose,K. Inami,A. Ishikawa,Y. Iwasaki,K.K. Joo,T. Kuniya,T. Matsumoto,I. Nagai,O. Nitoh,Yukiyoshi Ohnishi,Takayoshi Ohshima,T. Okabe,H. Ozaki,Y. Sakai,A. Sugi,A. Sugiyama,Jun-ichi Suzuki,Shiro Suzuki,N. Tan,J. Tanaka,Makoto Tomoto,K. Trabelsi,N. Ujiie,S. Uno,K. Yoshida +28 more
TL;DR: The Central Drift Chamber of the BELLE detector at the KEK B-factory is a cylindrical wire chamber device that uses a helium-based gas and aluminum field wires and is situated in a 1.5 T magnetic field as discussed by the authors.
Journal ArticleDOI

Journal ArticleDOI
Z-trigger system with the BELLE central drift chamber
Makoto Tomoto,Takayoshi Ohshima,Shiro Suzuki,A. Sugiyama,K. Yoshida,T. Matsumoto,T. Okabe,A. Ishikawa,K. Inami,I. Nagai,M. Hirose,K. Fujimoto,A. Sugi,M. Akatsu,Y. Sakai,S. Uno,Y. Iwasaki,Jun-ichi Suzuki,N. Ujiie,Y. Fujita,K. K. Joo,O. Nitoh,H Hirano +22 more
TL;DR: In this article, a fast Z-trigger system with the BELLE Central Drift Chamber was proposed to reduce the false trigger rate from caused by the spent electrons or positrons interacting with the material around the beam pipe.
