0010 <comment>
0011 - The detector length based on the 0.2*m step size and 4 layers.
0012 - I start from the downstream side of the B0 magnet and an arbitrary offset
0013 which puts the downstream of the detector 10cm from the end of the magnet.

0172 20um resolution = 75um "pixels", but this is "effective", since we assume charge sharing in the real-life 500um AC-LGADs - this may need to addressed differently in simulations later via digitization
