Study of the Tracking Method and Expected Performance of the Silicon Pixel Inner Tracker Applied in BESIII
Qinglei Xiu, Mingyi Dong, Weidong Li +8
The inner drift chamber of the BESIII is encountering serious aging problem after five year's running. For the first layer, the decrease in gas gain is about 26% from 2009 to 2013.…
Study of cluster reconstruction and track fitting algorithms for CGEM-IT at BESIII
Yue Guo, Liang-Liang Wang, Xu-Dong Ju +12
Considering the aging effects of existing Inner Drift Chamber (IDC) of BES\uppercase\expandafter{\romannumeral3}, a GEM based inner tracker is proposed to be designed and construct…
Aging effect in the BESIII drift chamber
M. Y. Dong, Q. L. Xiu, L. H. Wu +9
As the main tracking detector of BESIII, the drift chamber works for accurate measurements of the tracking and the momentum of the charged particles decayed from the reaction of BE…
A new inner drift chamber for BESIII MDC
M. Y. Dong, Z. H. Qin, X. Y. Ma +7
Due to the beam related background, the inner chamber of BESIII MDC has aging effect after 5 years running. The gains of the inner chamber cells decrease obviously, and the max gai…
