− | - Alex continued his presentation (linked above) from the last meeting now showing the Y-residuals (along wire) as a function of the X-residuals (first plot), both measured w.r.t. avalanche (hit) position. Since the avalanche is always on the wire, the X-residuals represents the drift distance and the Y-residual the deflection of the drifting electron due to the magnetic field. The linear correlation means that the deflection is simply proportional to the drift distance, with a slope also proportional to the magnetic field. Garfield simulations confirm this. The Y-residuals are about 200 microns (second plot). | + | - Alex continued his presentation (linked above) from the last meeting now showing the Y-residuals (along wire) as a function of the X-residuals (first plot), both measured w.r.t. avalanche (hit) position. Since the avalanche is always on the wire, the X-residuals represents the drift distance and the Y-residual the deflection of the drifting electron due to the magnetic field. The linear correlation (third plot) means that the deflection is simply proportional to the drift distance, with a slope also proportional to the magnetic field. Garfield simulations confirm this.
