Abstract :
The effect of high background illumination on the positioning resolution of the LEP and 4Q detector is studied. High background illumination lowers the noise sensitivity of the LEP, whereas the noise sensitivity of the 4Q detector remains unchanged. The noise sensitivity drop roughly from 0.5 to 0.3 was demonstrated in the case of the LEP. This means that by using an LEP instead of a 4Q detector, better resolution in high background illumination could be achieved despite the higher inherent noise level of it
