Ion Ray Gun

I found the following schematic from online sources. It’s about generating and launching ions. I did not built this circuit. But I’ll present some ideas on how to focus ions so that they will travel a longer distance.

Electrons gather at sharp points in metals. Electrons are emitted from a needle like sharp point as shown in Fig. 2. A negatively-charged plate may be used as an electron reflector to focus electrons along a line, thus producing a tight beam as shown in Fig. 1(b). Even a tighter beam is possible if the needle point is replaced with the structure shown in Fig. 1(c), though experimental verification is needed. To avoid loss due to corona, the entire wire and the reflector, except the sharp emitter, should be covered by an isolating material such as silicon etc. and surface variations should be very smooth.

Configuration shown in Fig. 3 can be used to bunch electrons using a magnetic field. Later, if the magnetic field is cut rapidly, bunched electrons are released and due to the focusing effect of the negatively charged reflector (NCR), they can be launched on to a target. A pulsed magnetic field would do the job if it’s generated by a pulsed capacitor discharge. So, if a HV capacitor is discharged on to a solenoid through an...
