... head size. Copper will work harden when bent or formed. Too much work hardening can cause collapse of tubing. If the copper gets hard to work, it can be annealed by heating it red hot with a torch and then water quenching. Remember that copper is “hot short” and will break if bent or stretched when...

The magnetic field in the deflection coils will cause the electron beam to scan the sample (it is also possible to keep the beam on a single spot on the sample, i.e., when a local analysis is required). As the beam scans the image, several...
