Statement of Work Our team will model an existing X-ray source and develop an electrostatic lens in order to create a more controlled X-ray transmission and enable the coupling of a lens to the existing X-ray optics. If time allows, we will produce a 3D print prototype of the lens and housing. We will place this focusing lens between the electron multiplier and the electron target in the existing MXS.

Our Questions Make us a name! o Choices: ElOpE, Electron Optics, EEL, Eeyore, EFL Do you really want us to use an Einzel Lens? Or could we look at other possible lenses? Would it be feasible for us to modify the electron multiplier at all? Would you recommend us looking at any other software packages for the sake of validation? (i.e. LENSYS) Website! Where is it? Should the lens be modifiable once it is optimized? (i.e. interface it with hardware or USB peripherals, changeable focal length, etc.) Should we look at changing any properties of the electron beam, i.e. accelerating it/changing the energy?
