Conclusion

We have presented a double humped electron velocity distribution, which is produced by secondary emisson of electrons from a fine meshed grid. The distribution can be easily modified by varying the grid potential. Preliminary investigation of the noise spectrum shows that plasma modes of well defined frequencies and wavelengths are driven unstable.
