Thanks a lot, we are investigating thin film scintillators (400nm) and the option of a mylar drift tube.

Thanks for the feedback, I updated the question with a description of the experiment. As you can see I do not want to measure the electron momentum, but the specific ionization in the gas

comment Single electron non-perturbing detector
One possible idea is to try and detect the fleeting magnetic field generated by the movement of the electron. The magnetic field is from a moving particle of charge e at a radius r = 1mm from the perticle is: B = -mu_0 * e / (4 * pi) * gamma *c / (r^2) = -0.0018 nano Tesla If I was to use a square coil of side l = 1cm the flux of the B field in the coil would be flux = l*B.integral(r,r_0,r_0+l) fem = flux / dt < 0.55 micro Volt using dt = l/c (which is too small, but it's just to get an upper value). With 100 loops and an amplifier I could see this on my oscilloscope...
