TN65.1: "TEC Resolution at 60 and 100Torr (Monte Carlo Drift)"

Posted as a response to TN-65.

Addendum, 14 April 2004

TN65.2: "GARFIELD simulation of the manufactured TEC with field wires"

Edge effects are minimized. Value of possible field wires HV is analysed. Distribution of primary electrons from surface muon, positron and pion in DME and ISO gas at different pressures is calculated. STR, time and space resolution has been calculated for surface muon and positron in ISO and DME gas.

TN65.3: "GARFIELD optimization of TEC"

Several possible improvements of the existing TEC are proposed.

Addendum, 29 November 2004

TN65.4: "One dimension TEC at B=2T"

The proposed TEC could be used as a tool for direct measurement and optimization of $P_\mu$ inside E614 magnet after fringe field. This is the tool for direct alignment of beam and magnetic field axis. This is tool also for direct investigation an influence of beam parameters on $P_\mu$ value.
