Method and subsystem are provided for determining a sequence in which microstructures are to be processed at a laser-processing site by taking into account microstructures located near travel limits of a motor-driven stage. The detector arrangement includes a detection element and a collector electrode configured to collect charged particles released from the detection element upon impact of signal charged particles. The first initial product sub-chambers and second initial product sub-chambers communicate with respective manifolds, which in turn communicates with an exterior of the electrolysis chamber through respective ports. Or, different reactions are completed with different catalysts for different purposes. Tightening the test bolt will cause the bolt to compress the piston and cylinder which will pressurize the hydraulic chamber.
