To meet with requirements of BESIII experiment, the main tracking device is a cylindrical drift chamber with small-cell geometry, using a helium-based gas and operating in a IT magnetic field. A cosmic ray test without magnetic field has been carried out. Preliminary results show that the rms of the residual distribution is 168 mum after the pre-alignment and the calibration of T0 and time-to-distance relation.

Abstract A luminosity monitor (LM) was constructed at Beijing Electron Positron Collider (BEPC) responsible for measuring the colliding luminosity of BEPC. Being a part of the Beijing spectrometer (BES), which is a large major detector of the BEPC, the LM is also capable of providing the integrated luminosity for physics study in BES. By various means, such as fine design and careful manufacture of various counters, precise positioning of the LM, employing multifold and delay coincidences, etc., the LM is able to measure a relatively precise luminosity with a significantly suppressed background, e.g. the first colliding of BEPC in 1988 was detected and announced in time by the LM with a luminosity of 5 × 1028/cm2 s. Besides, some useful information was provided by the LM to assist the proper operation of the BEPC. In this paper, the construction, operation, experimental results and the error analysis of the LM are presented in detail.
